Abstract
There have been many studies done around the world considering the
effectiveness of technical analysis. To name a few, Sahli N. Nefli (1991); Brock,
Lakonishok, and LeBaron (1992); Neely, Christopher, Weller, and Dittmar (1997); and
Salih N. Nefli and Polinaco (1984), etc. provided evidence that technical analysis can
predict price movements or developed models of market in which investors benefit from
conditioning of historical information. In Vietnam, only a few empirical studies about
technical analysis have been implemented. This paper, with a purpose to explore market
inefficiencies, aims to investigating the effectiveness of investment strategies using 3
most popular technical indicators (MA, MACD, and RSI) taking into account market
conditions, with and without trading costs and transaction fees. With this approach, the
study enhances conclusions that could be applicable for both market efficient conditions
and market inefficient conditions, which is suitable for a young and dynamic market like
Vietnam.
In order to test the performance of the technical analysis in different market
condition, the data in this study will be taken from Ho Chi Minh stock exchange market
for the investment period from 01/01/2009 to 01/01/2012. During this time, investors had
experienced 3 different market conditions which are up-trend, down-trend and sideways.
The collected data included 140 stocks. Funds and preferred stocks were excluded and
some needed assumptions about data and liquidity were set up before the trading
recoding process take place.

Chapter One - Introduction
1. Statement of the Problem
Within stock market, there are two approaches for stock price evolution analysis.
In one hand it is the fundamental analysis, which takes into account future prospects of
firms through accounting and financial information of the company beside other data
about firms’ operations. Fundamental analysis usually aims to developing company
value.
The technical analysis stands in the other hand. This kind of analysis will try to
forecast future stock trend through technical indicators. In order to develop an automated
system to stock market prediction and analysis, the most common solution is to turn to
technical analysis, as information needed is limited to stock price history of the value to
be studied. While fundamental analysis requires a deeper training and wider data set
which include a lot of hard measuring variables.
As a study of Pring (1980) shows that technical approach to investment is
essentially a reflection of the idea that the stock market moves in trends which are
determined by changing attitudes of investors to a variety of economic, monetary,
political and psychological forces. The art of technical analysis is to identify changes in
such trends at an early stage and to maintain an investment posture until a reversal of that
trend is indicated. By studying the nature of previous market turning points, it is possible
to develop some characteristics which can help identify major market tops and bottoms.
Technical analysis is therefore based on the assumption that the history will repeat, it
means that people will continue to make the same mistakes that they made in the past.
1
Refer to this conflict between fundamental analyst and technical analyst, many
studies had been conducted. Some have found results consistent with the practitioner’s
view by providing evidence that technical analysis can predict price movements or by
developing models of market in which investors benefit from conditioning of historical
information. For example, Sahli N. Nefli (1991); Brock, Lakonishok, and LeBaron
(1992); Neely, Christopher, Weller, and Dittmar (1997); and Salih N. Nefli and Polinaco
(1984) cited by Sewell (2008) tests different trading rules and find evidence consistent
that technical analysis provide incremental information beyond that already incorporated
into the current price. In theory, Sorensen (1984) and Brown and Jennings (1989)
examine settings in which privately informed investors use past prices to determine
whether their information has been revealed to the market or to learn about the private
signals of other traders, respectively. Similarly, Blume, Lawrence, Easley, and O’Hara
(1994) demonstrate that volume may provide relevant information if prices do not react
immediately to new information. Furthermore, there is a growing literature examining the
possibility that common biases in human judgment lead to market inefficiencies.
Meanwhile, according to Murphy (1999), technical analysts believe that investors
collectively repeat the behavior of the investors that preceded them. To a technician, the
emotions in the market may be irrational, but they exist. Because investor behavior
repeats itself so often, technicians believe that recognizable (and predictable) price
patterns will develop on a chart.
Technical analysis provides analyst a series of indicators as a main tool in
analyzing stock movement. According to Achelis (1997), an indicator is a mathematical
calculation that is applied to security’s price and/or volume fields. Price data includes any
2
combination of the open, high, low or close over a period of time. Some indicators might
use only the closing prices, while others incorporate volume and open interest into their
formulas. Indicators use those price data to produce some specific points or lines. Those
results could be used to anticipate changes in price.
Most empirical studies of technical analysis, include E. Fama and Blume (1966),
conclude that technical analysis is not useful for improving returns. In contrast, a more
recent study demonstrates that a relatively simple set of technical trading rules possess
significant forecast power for changes in markets for the long sample period. This paper
will test the performance of technical analysis by using a set of trading rules which are
based on some popular technical indicators in Vietnam market in a recent period of time.
2. Research Objectives
This study aims at exploring the effectiveness of investment strategies which are
based on technical indicators, namely MACD (Moving Average Convergence and
Divergence), RSI (Relative Strength Index) and MA (Moving Average).
3. Research Scope
This research will analyze the performance of three technical indicators: MACD
(Moving Average Convergence Divergence), RSI (Relative Strength Index) and MA
(Moving Average). The test will be applied for data on listed stocks on Ho Chi Minh
stock exchange market (UPCOM stock exchange market and Hanoi stock exchange
market are excluded). Then, the index in this paper will be understood as the index in Ho
Chi Minh stock exchange market only. Only joint stock companies are included in the
test, all funds are excluded. This research focuses on common stock only. All of preferred
stocks are excluded.
3
The collected data are the daily close price, daily trade volume, and firm’s market
capitalization in three years from 01/01/2009 to 01/01/2012. Only companies which
classified the time-length data are included in the test. All of the other companies will be
excluded. So, there are 140 classified stocks during this time length that satisfy the
condition of the test.
4. Research Significance
This research brings a better understanding of using technical analysis and
indicators in Ho Chi Minh stock exchange market. It also provides a better insight into
the stock investment. Besides that, this research provides more information about Ho Chi
Minh stock exchange market, helps to get deeper understanding about some specific
aspects and characteristics of the market, and of course this could be a good guideline for
stock investment.
The study of technical indicators is very important, especially in the business
fields of learning. It is very significant for understanding stock behavior, the factors that
affect capital return, and it helps us realize investment opportunity. We learn to
understand why stocks tend to act in their ways; hence, we learn how to meddle with
them. The research gives us patterns wherein we can predict whether our securities would
be having generated return or not.
The results of this research can be a reference for the functional agencies to make
trading decision. In addition, investors could have a better understanding about the
significance of technical analysis and its potential impact on their portfolio return,
helping them on choosing stocks and making decisions. Furthermore, this research also
provides concepts and discussion, enriching more understandings about our stock
4
exchange market as well as applications of some technical strategy for Vietnamese
investors.

Chapter Two: Literature Review
1. Investment and technical analysis
The philosophy behind technical analysis in sharp contrast to the efficient market
hypothesis, which contends that past performance, has no influence on future
performance or market values. Technical analysis also is different from principles of
fundamental analysis, which involves making investment decisions based on the
examination of the economic environment and firm activities to arrive at intrinsic value
of an asset. Different from efficient market hypothesis or fundamental analysis, technical
analysis involves the examination of historical market data such as prices and trading
volume to help estimate the future price trends and therefore investment decision. Having
said this, it is admitted that in making investment decisions, buying or selling stocks,
technical analysts also use economic data that are usually separated from the stock or
bond market. Therefore, technical analysis is an alternative method of making investment
decision (Reilly and Brown, 2006).
Numerous empirical studies have tested the profitability of various technical
trading systems, and many of them included implications about market efficiency.
According to Park and Irwin (2004), more than 130 empirical studies have examined the
profitability of technical trading rules over the four decades back. For example, Brock et
al. (1992) found support for technical trading rules on the Dow Jones Index. Following
their study the interest in testing the profitability of technical trading rules has grown
considerably. Several authors have presented supportive evidence in emerging markets
about profitability of technical trading rules.

1.1
Investment Strategy
1.1.1
Active strategy
Active management refers to a portfolio management strategy where the manager
makes specific investments with the goal of outperforming an investment benchmark
index. While passive management will often invest in an index fund since they expect a
return that closely replicates the investment weighting and returns of a benchmark index.
Ideally, the active manager exploits market inefficiencies by purchasing stocks
that are undervalued or by short selling securities that are overvalued. Either of these
methods may be used alone or in combination. Depending on the goals of the specific
investment portfolio, hedge fund or mutual fund, active management may also serve to
create less volatility (or risk) than the benchmark index. The reduction of risk may be the
goal of creating an investment return greater than the benchmark (Malkiel, 1996).
Active portfolio managers may use a variety of factors and strategies to construct
their portfolio(s). These include quantitative measures such as price–earnings
ratios and PEG ratios that attempt to anticipate long-term macroeconomic trends (such as
a focus on energy or housing stocks), and purchasing stocks of companies that are
temporarily out-of-favor or selling at a discount to their intrinsic value. Some actively
managed funds also pursue strategies such as risk arbitrage, short positions, and asset
allocation. Indicator-led trading strategies are used as a tool to decide trading points for
active traders as technical indicators based on statistics of historical prices and volume to
decide the market trend and therefore the price directions of stocks. The effectiveness of
an actively managed investment portfolio obviously depends on the skill of the manager
and research staff but also on how the term active is defined (Hebner, 2007).
8
In this study, active strategy will be applied using technical indicators which are
MA, MACD and RSI. Specific trading rules will be set up based on those three technical
indicators. Stocks will be traded actively over investment period using trading signals
which are stated by those three technical indicators by following trading rules strictly.
1.1.2
Passive Strategy
Two common followed strategies by passive investors are: buy and hold strategy
and indexing strategy (Andre & William, 1995):
Buy and hold strategy: an investor who follows buy and hold strategy selects a
portfolio and stays with it. Obviously, such an investor chooses a portfolio that
promises to meet his investment objectives and spend time and effort in his
initial selection.
Indexing strategy: if the capital market is efficient, effort to find underpriced
securities or to time the market may be futile. The philosophy is that they
assume that most investors are unlikely to outperform the market. Hence, they
may build a portfolio that mirrors a well-known index.
This research considers the passive buy and hold strategy as the benchmark to
evaluate the performance of active strategy. The indexing strategy is not concerned in this
research. In this paper, passive strategy will be understood as buy and hold strategy,
which means that portfolios follow passive buy and hold strategy will make only 1 buy
decision at the beginning and 1 sell decision at the end of investment period.
1.2
Technical Analysis
Technical analysis is the study of prices, with charts being the primary tool. The
technical approach to investment is essentially a reflection of the idea that prices move in
9
trends which are determined by the changing attitudes of investors toward a variety of
economic monetary, political and psychological forces… Since the technical approach is
based on the theory that the price is a reflection of mass psychology (“the crowd”) in
action, it attempts to forecast future price movement on the assumption that crowd
psychology moves between panic, fear and pessimism on one hand and confidence,
excessive optimism, and greed on the other (Pring, 1980).
The roots of modern-day technical analysis stem from the Dow Theory, developed
around 1900 by Charles of Dow, founder Wall Street Journal. Brock et al. (1992), and
Salih N. Nefli and Polinaco (1984) claim in their research that the first illustration of
technical analysis is the discussion of Dow theory in Rhea. Stemming either directly or
indirectly from the Dow Theory, these roots include such principles as the trending nature
of prices, prices discounting all known information, confirmation and divergence, volume
mirroring changes in price, and support/resistance (Achelis, 1997).
Any discussion of technical analysis using price and volume data should begin
with consideration of Dow Theory because it was among the earliest work on this topic
and remain the basis for many technical indicators (Glickstein & Rolf, 1983 cited by
Reilly & Brown, 2006). Dow described stock price as moving in trend analogous to the
movement of water. He postulated three types of price movement over time: (1) major
trends that are like tides of the ocean, (2) intermediate that resemble waves, (3) short-run
movement that like ripples. Follower of the Dow Theory attempt to detect the direction of
the major trend (tide), recognizing that intermediate movement (waves) may occasionally
move in opposite direction. They recognize that major market advance does not go
10
straight up but, rather, includes small price declines as some investors decide to take
profits.
Pring (1980) outline three principles that guide the behavior of technical analysts.
Those three principals were mainly based on the famous Dow Theory. The first is that
market action (prices and transactions volume) discounts everything. The second is that
asset prices move in trend. And the third is that history repeats itself (J. Neely & Weller,
2011 cited by Sewell (2008)).
Technical analysts believe that the intrinsic value of a firm or its estimated
earnings-potential, and the demand and supply information, is insufficient to predict its
future prices. Instead, they rely on statistical methods and collective psychology
techniques, and use data charts and computer programs, to study past movements in
prices and trading volumes to detect current and future trends. Most technical analysis is
short- or intermediate-term, and is based on three major tenets: history repeats itself what
goes around comes around, prices move in trends and usually follow known patterns, and
current market price of a stock
or commodity reflects the effect of all available
information about it (Achelis, 1997).
A fundamental principle of technical analysis is that a market's price reflects all
relevant information, so their analysis looks at the history of a security's trading pattern
rather than external drivers such as economic, fundamental and news events. Therefore,
price action tends to repeat itself due to investors collectively tending toward patterned
behavior – hence technical analysis focuses on identifiable trends and conditions.
Technical analysis is not limited to charting, but it always considers price
trends. For example, many technicians monitor surveys of investor sentiment. These
11
surveys gauge the attitude of market participants, specifically whether they
are bearish or bullish. Technicians use these surveys to help determine whether a trend
will continue or if a reversal could develop; they are most likely to anticipate a change
when the surveys report extreme investor sentiment. Surveys that show overwhelming
bullishness, for example, are evidence that an uptrend may reverse; the premise being
that if most investors are bullish they have already bought the market (anticipating higher
prices). And because most investors are bullish and invested, one assumes that few
buyers remain. This leaves more potential sellers than buyers, despite the bullish
sentiment. This suggests that prices will trend down, and is an example of contrarian
trading (Kirkpatrick & Dahlquist, 2006).
1.2.1
Dow Theory
The Dow Theory on stock price movement is a form of technical analysis that
includes some aspects of sector rotation. Dow theory has six basic tenets: (1) the market
has three movements, (2) market trends have three phases, (3) the stock market discounts
all news, (4) stock market averages must confirm each other, (5) trends are confirmed by
volume, and (6) trends exist until definitive signals prove that they have ended
(Glickstein & Rolf, 1983 cited by Reilly & Brown, 2006).
The basis of Dow theory is based on:
The market has three movements: the "main movement", primary movement or
major trend may last from less than a year to several years. It can be bullish or bearish.
(2) The "medium swing", secondary reaction or intermediate reaction may last from ten
days to three months and generally retraces from 33% to 66% of the primary price
change since the previous medium swing or start of the main movement. (3) The "short
12
swing" or minor movement varies with opinion from hours to a month or more. The three
movements may be simultaneous, for instance, a daily minor movement in a bearish
secondary reaction in a bullish primary movement.
Market trends have three phases: Dow Theory asserts that major market trends are
composed of three phases: an accumulation phase, a public participation (or absorption)
phase, and a distribution phase. The accumulation phase (phase 1) is a period when
investors "in the know" are actively buying (selling) stock against the general opinion of
the market. During this phase, the stock price does not change much because these
investors are in the minority demanding (absorbing) stock that the market at large is
supplying (releasing). Eventually, the market catches on to these astute investors and a
rapid price change occurs (phase 2). This occurs when trend followers and other
technically oriented investors participate. This phase continues until rampant speculation
occurs. At this point, the astute investors begin to distribute their holdings to the market
(phase 3).
The stock market discounts all news: stock prices quickly incorporate new
information as soon as it becomes available. Once news is released, stock prices will
change to reflect this new information. On this point, Dow Theory agrees with one of the
premises of the efficient market hypothesis.
Stock market averages must confirm each other: in Dow's time, the US was a
growing industrial power. The US had population centers but factories were scattered
throughout the country. Factories had to ship their goods to market, usually by rail. Dow's
first stock averages were an index of industrial (manufacturing) companies and rail
companies. To Dow, a bull market in industrials could not occur unless the railway
13
average rallied as well, usually first. According to this logic, if manufacturers' profits are
rising, it follows that they are producing more. If they produce more, then they have to
ship more goods to consumers. Hence, if an investor is looking for signs of health in
manufacturers, he or she should look at the performance of the companies that ship the
output of them to market, the railroads. The two averages should be moving in the same
direction. When the performance of the averages diverges, it is a warning that change is
in the air.
Trends are confirmed by volume: Dow believed that volume confirmed price
trends. When prices move on low volume, there could be many different explanations. An
overly aggressive seller could be present for example. But when price movements are
accompanied by high volume, Dow believed this represented the "true" market view. If
many participants are active in a particular security, and the price moves significantly in
one direction, Dow maintained that this was the direction in which the market anticipated
continued movement. To him, it was a signal that a trend is developing.
Trends exist until definitive signals prove that they have ended: Dow believed that
trends existed despite "market noise". Markets might temporarily move in the direction
opposite to the trend, but they will soon resume the prior move. The trend should be
given the benefit of the doubt during these reversals. Determining whether a reversal is
the start of a new trend or a temporary movement in the current trend is not easy. Dow
Theorists often disagree in this determination. Technical analysis tools attempt to clarify
this but they can be interpreted differently by different investors.

1.2.2
Technical Indicators
Technical indicators are distinguished by the fact that they do not analyze any part
of the fundamental business, like earnings, revenue and profit margins. Technical
indicators are used most extensively by active traders in the market, as they are designed
primarily for analyzing short-term price movements and making trading decisions,
picking stocks, buying and selling decisions. To a long-term investor, most technical
indicators are of little value, as they do nothing to shed light on the underlying business
(Caginalp & Laurent, 1998).
1.2.2.1 Moving average convergence divergence (MACD).
MACD is a technical analysis indicator created by Gerald Appel in the late 1970s,
has become one of the most popular of technical tools, used by short- and longer-term
investors in the stock, bond, and other investment markets. According to Appel (1999),
technical analysis is about the best stock-market timing tools. Appel smoothed out the
noise of shorter-term price fluctuations by moving average so as to more readily be able
to identify and define significant underlying trends.
The formula of exponential moving average is as below:
EMA (day i) = WEIGHT (current) x DATA (day i) + WEIGHT (moving average) x
Moving Average (day i-1)
Where
WEIGHT(current): is the weight of current day’s data in the exponential moving
average and its calculation as follows:
WEIGHT (current) = 2/ (number of day in moving average + 1)
15
WEIGHT(moving average) : is the weight given to the moving average in the
calculation of the exponential moving average and its determined formula is as
follows:
WEIGHT (moving average) = 100% - WEIGHT (current)
In his paper, Appel (1999) introduces the formula of MACD as below:
MACD = EMA (12) – EMA (26)
Where
MACD: is Moving Average Convergence/Divergence value
EMA(12): current value of the shorter exponential moving average (12-day)
EMA(26): current value of the longer exponential moving average (26-day)
The period for the moving averages on which an MACD is based can vary, but the most
commonly used parameters involve a faster EMA of 12 days, a slower EMA of 26 days,
and the signal line as a 9 day EMA of the difference between the two. It is written in the
form, MACD (faster, slower, and signal) or MACD (12, 26, and 9).
The build of MACD "oscillator" or "indicator" include three signals, calculated
from historical price data, most often the closing price. The indicator is represented by
three lines. These three signal lines are: the MACD line, the signal line (or average line),
and the difference (or divergence). The term "MACD" may be used to refer to the
indicator as a whole, or specifically to the MACD line itself. The first line, called the
"MACD line", is calculated by the difference between a "fast" (short period) exponential
moving average (EMA), and a "slow" (longer period) EMA. Those two lines are usually
called the MACD line and signal line. MACD indicator was formed based on those basic
Concepts:
16
MACD represents the difference of the short-term exponential moving average
minus the long-term exponential average. When market trends are improving,
short-term averages will rise more quickly than long-term averages. MACD lines
will turn up above 0.
When market trends turned down, shorter-term averages will tend to fall below
longer-term averages and then the MACD lines will fall below 0.
Weakening trends are reflected in changes of direction of MACD line, but clear
trend reversals are not usually considered as confirmed until other indications take
place.
Short-term moving averages will move apart (diverge) and move together
(converge) with longer-term moving averages. Hence, the indicator name moving
average convergence-divergence.
Since the MACD is based on moving averages, it is inherently a lagging indicator.
However, in this regard the MACD does not lag as much as a basic moving average
crossing indicator, since the signal cross can be anticipated by noting the convergence far
in advance of the actual crossing. As a metric of price trends, the MACD is less useful for
stocks that are not trending (trading in a range) or are trading with erratic price action.
The MACD is only as useful as the context in which it is applied. An analyst might apply
the MACD to a weekly scale before looking at a daily scale, in order to avoid making
short term trades against the direction of the intermediate trend.
Signal–line crossovers are the primary cues provided by the MACD. The standard
interpretation is to buy when the MACD line crosses up through the signal line, or sell
when it crosses down through the signal line. The upwards move is called a bullish
17
crossover and the downwards move a bearish crossover. Respectively, they indicate that
the trend in the stock is about to accelerate in the direction of the crossover.
1.2.2.2 Relative Strength Index (RSI)
The Relative Strength Index, introduced by Wilder (1988), is one of the most
well-known momentum oscillator systems. Momentum oscillator techniques derive their
name from the fact that trading signals are obtained from values which “oscillate” above
and below a neutral point, usually given a zero value. In a simple form, the momentum
oscillator compares today’s price with the price of n-days ago (Wilder, 1988).
The upward change U or downward change D for each trading period is
calculated. Up periods are characterized by the close being higher than the previous
close:
Conversely, a down period is characterized by the close being lower than the
previous period's (note that D is nonetheless a positive number),
If the last close is the same as the previous, both “U” and “D” are zero. The
average U and D are calculated using an n-period exponential moving average (EMA)
but with an equal-weighted moving average in Wilder's original version. The ratio of
these averages is the relative strength or relative strength factor:
18
If the average of D values is zero, then according to the equation, the RS value
will approach infinity, so that the resulting RSI, as computed below, will approach 100.
The relative strength factor is then converted to a relative strength index between 0 and
100.
The exponential moving averages should be appropriately initialized with a
simple average using the first n values in the price series. As Wilder (1988), the
momentum oscillator measures the velocity of directional price movement. When the
price moves up very rapidly, as some point it is considered to be overbought; when it
moves down very rapidly, at some point it is considered to be oversold. In either case, a
reaction or reversal is imminent. Momentum values are similar to standard moving
averages, in that they can be regarded as smoothed price movements. However, since the
momentum values generally decrease before a reverse in trend has taken place,
momentum oscillators may identify a change in trend in advance, while moving averages
usually cannot.
The RSI is most typically used on a 14 day timeframe, measured on a scale from
0 to 100, with high and low levels marked at 70 and 30, respectively. Shorter or longer
timeframes are used for alternately shorter or longer outlooks. Wilder believed that tops
and lowest are indicated when RSI goes above 70 or drops below 30. Traditionally, RSI
readings greater than the 70 level is considered to be in overbought territory, and RSI
19
readings lower than the 30 level are considered to be in oversold territory. In between the
30 and 70 level is considered neutral, with the 50 level a sign of no trend. In this study, 14
day timeframe will be used to calculate and draw the RSI indicator.
1.2.2.3 Dual Moving Average Crossover (MA)
Moving average based trading systems are the simplest and most popular trendfollowing systems among practitioners (Lui and Mole (1998) cited by Sewell (2008)).
According to Sahli N. Nefli (1991), the (dual) moving average method is one of the few
technical trading procedures that is statistically well defined. When the short-term trend
rises above or below the long-term trend, the Dual Moving Average Crossover system
generates trading signals.
Moving Average is an indicator that shows the average value of a security's price
over a period of time. When calculating a moving average, a mathematical analysis of the
security's average value over a predetermined time period is made. Average price moves
up or down as the securities price changes. A buy signal is generated when the security's
price rises above its moving average and a sell signal is generated when the security's
price falls below its moving average.
The study of Sewell (2008) states that the critical element in a moving average is
the number of time periods used in calculating the average. Sewell found that the
optimum number of months in the preceding chart would have been 43. The key is to find
a moving average that will be consistently profitable. The most popular moving average
is the 39-week (or 200-day) moving average. This moving average has an excellent track
record in timing the major (long-term) market cycles.
20
Tushar (1992) states in his study that Moving averages are a powerful tool for
analyzing the trend in a security. They provide useful support and resistance points and
are very easy to use. The most common time frames that are used when creating moving
averages are the 200-day, 100-day, 50-day, 20-day and 10-day. The 200-day average is
thought to be a good measure of a trading year, a 100-day average of a half a year, a 50day average of a quarter of a year, a 20-day average of a month and 10-day average of
two weeks. Moving averages help technical traders smooth out some of the noise that is
found in day-to-day price movements, giving traders a clearer view of the price trend. So
far we have been focused on price movement, through charts and averages. In the next
section, we'll look at some other techniques used to confirm price movement and
patterns. In this study, the moving average indicator will be defined as the dual cross of
moving average 200 day (slow line) and the moving average 30 day (fast line).
1.3
Previous Researches on technical analysis
Numerous empirical studies have tested the profitability of various technical
trading systems, and many of them included implications about market efficiency.
According to Park and Irwin (2004), more than 130 empirical studies have examined the
profitability of technical trading rules over the last four decades. For example, Brock et
al. (1992) found support for technical trading rules on the Dow Jones Index. Following
their study the interest in testing the profitability of technical trading rules has grown
considerably. Several authors have presented supportive evidence in emerging markets. \
The research of Ben, Rochester & Jared (2006) cited that Chaudhur and Wu
(2003) find that the technical trading rules could earn high profit since the random walk
hypothesis might not work in many emerging markets. Parisi and Vasquez (2000) show
21
huge profits to technical trading rules in the Chilean stock market. Bessembinder and
Chan (1998) find that the profit of technical trading rules could be exceed the transaction
costs in the emerging markets of Malaysia, Thailand, and Taiwan. Ito (1999) also tests
technical trading rules and finds profitability beyond transaction costs in Indonesian,
Mexican and Taiwanese equity indices. Finally, Ratner and Leal (1999) conduct a test in
markets of India, Korea, Malaysia, Philippines, Taiwan, Thailand, Argentina, Brazil,
Chile, and Mexico, and find some evidence of profit from technical trading rules in
Taiwan and Thailand markets.
Neely, Christopher, Weller, and Dittmar (1997) cited in their research that "Osler
and Chang (1995) construct a computer algorithm to identify head and shoulders pattern,
and look at the returns to this rule in several currencies over the period 1973-1994. With
bootstrap methodology they find evidence of significant profits for the mark and yen, but
not for the pound sterling, Canadian dollar, French franc or Swiss franc”.
Blanco, Sagi, Soltero, and Hidalgo (2004) test an application of technical trading
rules on Moving Average Convergence Divergence (MACD) from 2000 to 2005 of Dow
Jones Industrial Average (DJIA) and compare it with passive buy and hold strategy at the
same period of time. They prove that parameters of technical indicators can be improved
with Evolutionary Algorithms.
In Vietnam, Sang (2010) did a test and concluded that technical analysis earns
more return but also more profit. These studies provide a strong confirmation for using
technical analysis, especially in Vietnam stock exchange market. Furthermore, these
studies also state the different between indicators during the test. For example, Sang
found that the results of RSI and MACD are significantly different for the same portfolio.
22
Hung, H. Nguyen, & Yang Zhaojun (2013) conduct a paper considering whether
the moving average rules can forecast stock price movements and outperform a simple
buy-and-hold strategy over the period from July 2000 to March 2011 on Vietnamese data.
Hung and Yang concluded that the technical trading rules examined have strongly
predictive ability in term of Vietnamese data. The rules have greater forecasting power
for Vietnamese than those for some other Asian markets. The profitability of short-term
technical trading rules is better than that of longer-term ones. This study also confirm that
the (1,10,0) rule, (1,20,0) rule, and (1,50,0) rule are determined to be very effective in
Vietnamese stock market because they allow investors to make a large excess returns
before trading cost. Specially, Hung proves that the technical trading rules are profitable,
even after adjusting for trading costs.
2. Effectiveness of investment strategy
Effectiveness is always a critical concern of any investment. In financial sector,
especially in stock exchange market, effectiveness of a strategy will be measure by the
return of stocks which might include capital gain, dividend collected and any other form
of inflow by stock trading. Effectiveness measurement will be difficult due to various
aspects such as special market characteristic, micro and macro-economic situation, other
affects from other related markets.
In this paper, effectiveness of stock trading rules will be measure by simply
accumulate all of possible return from stocks trading in a specific investment period. To
be more specify, the effectiveness of a trading rule will be measure by the average return
from trading a set of stock portfolios using that trading rule in a period of investment.
Different trading rules could be compared to the others by using the average return of the
23
same portfolio in the same investment period. For example, effectiveness of indicator
MACD will be measure by the average return from trading a stock portfolio in 3 years
from 01/01/2009 to 01/01/2012. The effectiveness of indicator MACD could be
compared to the effectiveness of MA or RSI indicator by simply compare the average
return from the same stock portfolio trading in the investment period.
The return of stocks is calculated simply by the formula below:
R = (P1 – P0)/P0
Where
o R is the return of stock in a period of time.
o P1 is the sell price.
o P0 is the buy price.
3. T-Test two-sample for mean
After implementing the descriptive statistics, the 2 sample T-Test for means are
used to compare the performance of each stock group to the others respectively. The
Microsoft Office Excel Add-in software is used to give the result of T-Test with
confidence level of 95%. Results of the test will be calculated automatically by SPSS
software to check the hypothesis 1 and 2 in order. Unequal (or equal) sample sizes,
unequal variances T-Test formula will be applied as following:

Figure 2: Data Interpreting Process
Figure number 2 describes the process of collecting and interpreting data in this
research. All of data will be collected and handled through these 5 steps. First, data will
be collected according to investigate the effectiveness of active indicators strategies in Ho
Chi Minh market and scope as detailed in chapter 1 – Introduction.
Second, stock portfolio will be formed by technical indicators. In this research,
we focus on 3 different stage of the market which are up-trend, down-trend and sideway.
So, there are 4 portfolios based on 3 separate technical indicators and passive strategy for
each stage. In third step, detail rules and principle will identify “buy” and “sell” signal
based on 3 technical indicators. And then, the next step will focus on estimating portfolio
26
return and standard deviation. Finally, these portfolios will be compared across each other
using T-Test 2 samples for means.
1. Study Population and Data Collection
The collected data are daily prices which include open price, close price, highest
price, and lowest price on daily basis and trade volumes of each stock in 3 years from
01/01/2009 to 01/01/2012. During those years, the market was experienced 3 different
trends. Stocks which do not satisfy this time length will be excluded. So, there are 140
stocks included in the test.
At first, open price, close price, highest price, and lowest price on daily basis and
trade volumes of all classified stock was collected from website www.vndirect.com.vn
for the period of 3 years form 01/01/2009 to 01/01/2012 (including 749 daily price
observations).
Secondly, “buy” and “sell” signals are identified on the historical price graph
according to the collected data in the first step to calculate the return for each strategy.
Returns of each stock will be calculated and gathered into groups. All of the factors that
might affect to the return of trading stocks (such as dividend, interest, T+3 rules …etc.)
will be taken into account in the calculation of step 2.
2. Trading Rules
For active strategy, stocks are traded actively over time, “buy” and “sell”
decisions are made continuously overtime based on “sell” and “buy” signals of technical
indicators (meaning MACD, RSI, and MA). Each indicator has its own principles. In
order to ensure the validity of the test, trading rules are stipulated in advance for each
indicator and applied strictly during the whole investment period.
27
2.1 General trading rules
If the indicator states a “buy” signal or “sell” signal, then “buy” decision or “sell”
decision will be made with the price of the transaction dates. Stocks could be traded by
“trading cycle”. Each trading cycle begins with the “buy” decision and end with the
“sell” decision. So, there is no short-selling transaction during the tested period. In case
there are more than one “sell” signal is seen, only the first “sell” signal that follows the
“buy” signal is taken into account, the following “sell” signals will be skipped until we
have the next “buy” signal. Similarly, for the last “buy” signal toward the end of the
investment period, and there is no “sell” signal before the end of the investment period (it
means this trading cycle is not closed yet), then the stocks will be sold at the price of the
last trading day of the investment period to close this trading cycle to ensure the validity
of the test.
Furthermore, one trading cycle can begin when the previous one has not been
finished yet. In some cases, some “buy” signals might occur continuously or vice versa
for “sell” signal, and then trading cycles can be intersected each other’s. For example, if a
“buy” signal occurs and then 1 trading cycle begins with buy decision, it means we hold
stocks in account. Some days later, we expect for a “sell” signal to sell these stocks and
end up this trading cycle, but one more “buy” signal occurs and another trading cycle
begins. It means another buy decision is made even when we did not sell the stocks that
we bought in the first trading cycle, and we got some more stocks in account. And then, if
the indicator state a “sell” signal, all of stocks in account will be sold and both these two
trading cycles will be closed at the same time (Sang, 2010).
28
If the trading signals lead to the conflict with rule T+3, all of trading decision
must wait until the assets are transferred. By the law, the trading action will be done in
the next day. For example, if a “sell” signal occurs but the T+3 rule is still in effect (it
means the stocks that we bought are not transferred yet), then the trading action could not
be performed. But the real market, investors and brokers learn many ways to avoid this
difficulty. The bank can help investors to eliminate the effect of T+3 rule.
For example, in May Bank Kim Eng Securities Joint Stock Company, investors
might borrow stocks or cash from the bank to make trading action even when T+3 rule
still in effect. It means the bank will lend investors’ money to trade and then they will get
money back when it is transferred into investors’ account few days later. Besides,
Securities Company could lend investors stocks and then they can get stocks back when
they are transferred into investors’ account few days later.
2.2 Trading signals
The Microsoft Office Excel software is used to draw the indicator and give
exactly the trading signal. According to the concept of MACD indicator, the “buy” signal
occurs when the MACD line raise above the signal line (9-day period) and the “sell”
signal occurs when the MACD line fell below the signal line. A very similar method
could be used for MA. The “buy” signal occur when MA (30 days) line cross over the
MA (120 days) line.
RSI indicator use timeframe 14-day period, the “buy” signal occurs when the RSI
line fell below 30 and the “sell” signal occurs when the RSI line raise above 70. If these
signals satisfy all of general assumption and trading rules, the trading actions will be
29
done. These trading action results will be gathered and calculated automatically by
Microsoft Office Excel Add-in application.
3. Measurement of strategy effectiveness
In case of market efficiency, all transaction fees, taxes, T+3 rules … will be
excluded from the test and data implementing process. The results from those data will be
used to measure stocks’ return without inefficiency aspects. In the other hand, when the
inefficiency aspects take place, few assumptions will be made to ensure the feasibility of
the research. First, all of transactions are assumed to be done by an account in May-Bank
Kim Eng Securities Company. So, transaction fees will be calculated based on policy of
this company. According to transaction fee table quoted on the official website of MayBank Kim Eng Securities Company, the transaction fee for total transaction value under
VND 100 million/due is 0.35% total transaction value. Hence, the returns are calculated
automatically including capital gain (or loss) from buy and sell stocks and dividend
received (if any).
According to the Article 1 of Circular No. 12/8/2009 dated 160/2009/TT-BTC of
the Ministry of Finance guides income tax exemption in 2009 by Resolution No.
32/2009/QH12 dated 19.06.2009 of the National Association that individual transferable
securities are exempt from personal income tax from 01/01/2009 to end on 31/12/2009.
Since 01/01/2010, personal income from transfer of securities shall pay personal income
tax as stipulated in the Law on Personal Income Tax and Circular No. 84/2008/TT-BTC
dated 30/9/2008 of the Ministry of Finance
guiding perform the Circular No.
100/2008/ND-CP dated 09/08/2008 of the Government regulating in details some articles
of the Law on Personal Income Tax and 42/BTC-TCT Dispatch on 02/01/2009 Ministry
30
of Finance guides income tax deduction for stock transfer. The personal tax applied for
share ownership transferring is 0.1% on sell price or 20% on capital gain for one trading
cycle. In this research, 0.1% on sell price personal tax is applied.
The gain or loss of each transaction is calculated by the following formula:
S–B+D
G=
x 100%
B
Where:
o G – Gain (loss) per transaction (%)
o S = (Close price of the stock at the time the “sell” action is done) – (the
transaction fee and personal tax)
o B = (Close price of the stock at the time the “buy” action is done) + (the
transaction fee)
o D – dividend received relate to the trading cycle (if any)
Whenever the capital take break in the account (means the investors hold cash
instead of stocks), they got interest on that cash. In Vietnam market, each securities
company signed a contract with the bank; the investors will get the interest at rate for
Non-term Deposit Balance from that bank. In this research, all trading actions are done
by the account opened at Kim Eng May Bank Securities Company. So, the interest rate
for Non-term Deposit Balance of Eximbank will be applied. It is 3.6% p.a, equivalent to
0.01% per day.
So, returns of each stock for the whole investment period are calculated as the
following formula:
R
=
∑G + (N – n) x R
31
Where
o R – Average daily gain (loss) for the whole investment period (%)
o G – Gain (loss) per transaction (%)
o N – 730 days
o n – Total non-trading days in investment period
o R – 0.01%
32
Chapter Four – Results
This section will show the result of trading stocks following exactly the trading
rules and assumptions which were set up the methodology. These results include average
stock returns, standard deviation, and return distribution; those data will be displayed
under using bar chart and box plot. At first, all inefficiency aspects such as dividend,
trading fees, taxes, T+3 rules … will be excluded from the test. Secondly, those
inefficiency aspects will take place. The results of data with and without inefficiency
aspects will be compared to each other in order to test the effect of those inefficiency
aspects into the test results.

The figure above will show the return of stocks in the whole three years from
2009 to 2012. This figure illustrated the domination in average return of technical
indicators over passive strategy. The average returns of stocks during three years were
174%, 58%, 42% and 3% corresponding to RSI, MACD, MA and passive strategy.
Besides, standard deviation of MACD, MA, and passive strategy were almost the same
around 90% while the standard deviation of RSI indicator peaked into nearly 240%.
Secondly, the return of stocks during this three years period is broken down into 3
different separate period of time which represent for up-trend, down-trend and sideways
market situation. The figure above shows box plot of all three indicators and passive
trading in three different market stages (up-trend, sideway and down-trend).

During down-trend and sideway market stage, technical indicator (include RSI,
MACD and MA) showed no big differences compared to passive trading method. The
mean of stock returns during those two market stages from both technical indicators and
passive trading method fluctuated around 0. The situation was much better in up-trend
market stage, as the figure below, RSI indicator gained a significant higher average return
compared to passive trading method and the other two indicators. RSI got around 180%
of average return while MACD and passive trading method stood around 80% of average
return. MA indicator only got nearly 40% on average return during this up-trend period.
1.2
Data with inefficiency aspects
In overall, the data with inefficiency aspects was almost the same with the data
without those inefficiency aspects. The figure below shows the average stock return of

The average return of all three technical indicators and passive strategy reduce a
little bit due to the cost from inefficiency aspects. The average returns of RSI, MACD
and MA were corresponding to 163%, 47% and 31% while the average return of passive
strategy fall down below 0%. The standard deviation stood almost the same. RSI
indicator still got the highest standard deviation (double the others). The standard
deviation of MACD, MA and passive strategy were almost nearly to each other (around
90%).
2. T-Test Two Sample for Mean
2.1
Data without inefficiency aspects
The table below shows the T-Test result between the stock return of strategies
using three technical indicators and passive strategy for the period of three years from
2009 to 2012. First, all three technical indicators confirm the significant different in
average return in the comparison with passive strategy. Besides, there is no significant
different in average return between MACD and MA since those two indicators were built
on almost the same basic while RSI indicator confirm a significant different in the
comparison with the other two technical indicators.

trading method show a significant different results. During up-trend period, only RSI and
MA indicator show a significant different result while T-Test did not confirm that for
MACD indicator. Among technical indicators, when the market has formed a trend, the
results of those three indicators will be significant different. But when the market fall in a
sideway situation, the result between those three indicators will not confirm any
significant different.
2.2
Data with inefficiency aspects
Data with inefficiency aspects still keeps the same T-Test results compared to the
T-Test results of data without inefficiency aspects. The table below shows the T-Test
results of the comparison between all three technical indicators with passive strategy and
among those three technical indicators during three different period of time which
represent for up-trend, down-trend and sideways market situation.

The table below shows the T-Test results of the comparison between the data
without inefficiency aspects and data with inefficiency aspects. The data will be
compared in pair of each technical indicators corresponding to each market situation (uptrend, down-trend and sideways).
The table below shows that there are no significant different between average
return of stocks using the same technical indicators in the condition within and without
the inefficiency aspects. The results of all three technical indicators were completely the

Chapter Five – Discussion
In overall, the findings in descriptive analysis using box plot and column chart
suggested that the technical indicators was outperformed the passive trading method in
most cases. During the up-trend market, only RSI indicator show a significant higher
return compared to passive trading method. MACD got nearly the same result with
passive trading method while the return of MA indicator even lower than passive trading
method. For sideway and down-trend market, the technical indicators still brought a
significant higher return but the returns were not high.
The results from T-Test two samples for mean also confirm the significant
differences among those technical indicators. When the market has formed its trend
(either up-trend or down-trend) the return from technical indicators will be differently.
Otherwise, the differences will not be considered significantly. Especially, RSI indicator
tends to get higher return but higher risk too. The average return and standard deviation
of RSI indicator were much higher than the other indicators. The reason could come from
the nature of this indicator. RSI is a leading indicator while MACD and MA have more
characteristics of a lagging indicator.
As in the finding, the profit from “MA” indicator and “MACD” indicator were
lower than “RSI” indicator. The profit of active trading strategy using these technical
indicators comes from the fluctuation of stock prices. But these technical indicators were
formed by different factors and they got some different characteristics. “MA” indicator is
a lagging indicator which normally state trading signal later than leading indicator like
“RSI” while “MACD” stand in the middle. So, in a sideways movement of stock prices,
40
these 3 technical indicators are almost the same. But when the market trend has been
confirmed, the different between lagging and leading technical indicators will be
significant. Leading indicator like RSI will have the tendency to move forward the
market and promise higher return (if the market going up) and higher level of risk.
Lagging indicators tend to react a little bit later then the market since the data of those
kinds of indicator has been formed from the moving average. Thus, lagging indicator
might miss some potential opportunities by its late react.
The word “lagging” in “lagging indicator” could be understood as “slower”. The
“MA” indicator in this study might represent for all of lagging technical indicators. These
indicators almost got the same movement which is slower than the average market. So,
some opportunities might be missed cause of this late trading signal. In contrast, leading
indicator like “RSI” usually states trading signal before the average market. Thanks for
this fast respond leading indicator could take a lot of opportunities but also cause noises means false trading signal. Trading signal of technical indicator might be false sometimes
cause of quick change in stock price trend.
For example, a new trend of stock price has been formed. Leading indicator like
“RSI” will state trading signal before lagging indicator like “MA” did. But if the trend of
stock price changes instantly right after that, the trading signal stated by “RSI” indicator
might lead the investors to a false decision. This is called noise. Noise usually occurs in
leading indicator cases. It seems to be that lagging indicator is a better choice. But if we
take a closer look at the data, lagging indicator like “MA” usually has a lower number of
transactions than leading indicator like “RSI”. Besides, lagging indicator states trading
signal later, and then some profit will be missed.
41
According to the data, technical indicator returns dominate passive trading
method. In the up-trend market, this is very obvious to see. In sideways and down-trend
market, the returns of technical indicators still higher than passive trading method but all
of the returns were very low around zero. In the aspect of risk taking, “RSI” indicator was
a special case compared to the others. This indicator sometimes brought back a lot of
return but, of course, the threat high risk comes along with that. For example, during the
uptrend period, the return RSI indicator was more than 3 times of the others. But the
standard deviation of this group was more than 5 times of the others.
Transaction fees could be a concern for investors who follow active trading
strategy. Transaction costs are important to investors because they are one of the key
determinants of net returns. Transaction costs diminish returns, and over time, high
transaction costs can mean thousands of dollars lost from not just the costs themselves
but because the costs reduce the amount of capital available to invest. The number of
transaction cost move together with the number of transaction that we made. Since the
transaction fees are calculated according to the value of that transaction. Besides, active
strategy trades stocks actively overtime and then, the number of transaction would be a
lot higher. Otherwise, the data shows that inefficiency aspects such as trading fees,
dividend and taxes did not affect much on the results.

Chapter Six – Conclusion and Recommendation
1. Conclusion
This study serves the purpose of investigating the effectiveness of investment
strategies using technical against passive trading method. The data is from Ho Chi Minh
stock exchange market only (Hanoi and UPCOM market are excluded) for the investment
period from 01/01/2009 to 01/01/2012. The collected data were included 140 stocks in
total. All funds and preferred stocks were excluded and some needed assumptions about
data and liquidity were set up before we started the trading recoding process.
The study focus on 3 most popular technical indicators in Vietnam market which
are Moving Average (MA), Moving Average Convergence and Divergence (MACD) and
Relative Strength Index (RSI). The performances of these technical indicators were
confirmed by the previous studies in both Vietnam market and other countries.
In this research, active strategy was used to maximize the performance of those
technical indicators. The active investors used the support from technical analysis to
trading stocks actively during the investment period. All of transactions were tracked and
recorded in a excel file for each stock. The transaction cost and dividend were included in
the transaction recording process. Data with and without inefficiency aspects such as
trading costs, dividend, T+3 rules will be compared to each other. Descriptive statistic
and T-Test will be used to make the comparison of the means of these groups. Standard
deviation will be used as a tool to measure the level of risk for each group’s data.
Descriptive analysis was confirmed that technical indicators show different results
across market stages (up-trend, sideways and down-trend). In overall, the performances
of technical indicators were better than passive trading method. Technical indicators
43
could maximize the returns during up-trend period and minimize the lost when the
market declines. But minimizing the lost does not mean that it performs well. The returns
during sideways and down-trend market of technical indicators and passive strategy were
nearly zero.
T-Test statistic results illustrate a significant different between technical indicators
and passive trading method in sideways and down-trend market while only RSI indicator
stated a significant better result in up-trend market. “MA” indicator or lagging technical
indicator seems to be more stable compared to leading technical indicator (for example:
RSI). Return from “MA” indicator was lower than “MACD” or “RSI” indicator but it
also faces lower level of risk. “RSI” indicator raise higher return but it needs to bear a
very higher level of risk. Besides, technical indicators always have a higher number of
transactions since they trade stocks actively while passive trading method only has 1
transaction only. Furthermore, the effect of inefficiency aspects like dividend, trading
cost, and taxes on final return was not high. The results with and without inefficiency
aspects were almost the same by the confirmation of T-Test results.
2. Recommendation
Since the big differences across market stages, using leading technical indicators
like RSI is recommended for investors during the up-trend market to maximize the profit.
But if the market seems to be confused or declines, holding stocks during this time is not
a good choice for Vietnam current trading regulations. Although that the return of
technical indicators still higher than passive trading method but they only could reduce
the lost. Thus, investors should consider to use technical indicators to get more return
when the market perform well but they should not invest much in stock market during
44
crisis time even with the support from technical indicators. When the up-trend market is
confirmed, this study strongly recommends investors to use RSI indicator to increase the
profit.
The study also states that the performance of technical indicators might be
different. Each technical indicator will show a different result based on its own
characteristic. Investors’ risk tolerance is a very important factor to choose a specific
technical indicator since there are some differences between their risk and return. Leading
indicators could bring back higher return but the risk comes along. Risk taken investors
will prefer to use leading indicator and the risk adverse investors will prefer to use
lagging indicator. But as the results of this study, using lagging indicators only get almost
the same result with passive trading method. This type of technical indicators might not a
good choice for investors.
This study states that the transaction cost and dividend paid out were not an
important factors for technician in Ho Chi Minh market. Active strategies normally take
higher transaction cost and personal tax but a random amount of dividend paid out.
Active investor need to accept the higher cost of transaction fee and tax. Especially for
the case of MACD, this indicator shows a significant higher number of transactions
compared to the other indicators. But those numbers did not affect much on the return;
investors don’t need to pay attention on those aspects.
3. Limitation
There appear to be some limitations generated during the time carrying out this
study, which should be considered in future research. Firstly, Vietnam stock exchange
market started running about 13 years ago – at the time this research was accomplished.
45
Due to the limit of time length of the investment period, only 3 years data of stock trading
might not reflect all of market characteristics. The selection of time horizontal might
affect to the return stocks. Stock market usually follows a specific trend in a specific
period of time. Choosing a specific time length might reflect only the trend which the
market followed during that time only.
Some assumptions related data collecting and liquidity needs to be sated up in
order to ensure that the process of input data recording was conductible. These
assumptions might not valid in the real market and must be consider more careful in
further study. Furthermore, the companies with bigger amount of capital and higher
liquidity might attract more investors than the small one. It affects to the active strategies
more than passive strategy because trading stocks actively require higher level of
liquidity. In the real market, some trading signals may not able to implement because
there is no matching order. In consequently, capital firm size effect and liquidity effect
must be conducted in further study so that the comparison between the performances of
active strategies and passive strategy can be carried out more efficiently.
In addition, different markets have some different characteristics which might
lead to some different conclusions and affect much to the results. The research only focus
on Ho Chi Minh market only, Hanoi market and Up-com market are excluded from the
test. These markets have many different characteristics compared to Ho Chi Minh
market. These differences could lead us to some different results. Further research must
have some comparison between these markets in order to get a bigger overview.
Finally, the amount of money which is invested during the investment period was
not mentioned. This problem is related to the capital firm size effect. The bigger
46
companies usually got higher stock price compared to the other smaller companies. First,
investors can buy only a short amount of big stocks but a lot amount of small stocks. For
the big one, there is no big deal, but this inflow of cash will affect directly to that stock
price. So, the balance between supply and demand of that stock could change
dramatically and then, monopoly affect occurs. This phenomenon was not mentioned in
the research too. Any further study must take this in to account very seriously.
