population with securities market accounts in Vietnam is around 4%, and the government aims to increase the number of participants However, investing in the stock market carries significant risks, but it also offers substantial profit potential for investors To minimize risks and seize opportunities, our group has decided to participate in the "Stock Market" course under the guidance of the instructor This has provided us with an opportunity to invest in and access a new market, and the following report is the result of our stock market investment journey II Account opening process Introduce VPS company VPS Securities Joint Stock Company was established in 2006, when it was first established, it was called Vietnam Prosperity Joint Stock Commercial Bank Securities Joint Stock Company (VPBS) Currently, VPS has become one of the securities companies with the largest market share in Vietnam As of June 30, 2019, VPS has charter capital of VND 3,500 billion and total assets of VND 10,274 billion VPS Securities Company provides diverse, high-quality products and services, creating added value for businesses and investors including: stock brokerage, financial services, investment banking services, financial consulting and analysis As a financial intermediary organization, investment banking activities are the central focus of VPS's development orientation VPS provides financial services such as capital arrangement, securities underwriting, mergers and acquisitions (M&A) activities, consulting on determining business value, restructuring capital and debt in each project stage Reasons for choosing VPS company to open account a Brand of VPS securities company One of the most important factors in choosing a securities company is the brand of the securities company The brand name securities company is not big, the reputation is not high, the charter capital is low, the amount of money investors deposit is sometimes even larger than the company's charter capital Therefore, choosing a brand is an extremely important factor VPS is one of the securities companies that has many years of experience working in the securities field VPS used to be one of the securities companies belonging to VPBank VPS inherits VPBank's financial management capabilities b VPS Stock Transaction Fees There are many different types of fees that investors have to pay, but the most important are transaction fees and margin loan fees (margin interest rate), as for service fees and taxes, which securities company should an investor open an account at? same On December 27, 2018, the Ministry of Finance issued Circular No 128 regulating service prices in the field of securities applicable to securities trading organizations and commercial banks participating in the Vietnamese stock market According to this regulation, the maximum price of brokerage services for buying and selling stocks, fund certificates, and covered warrants (applicable to listed securities and securities registered for trading) is 0.5 % transaction value and no floor rate applies Regarding derivative securities services, the maximum price of futures contract brokerage services is 15,000 VND/Index futures contract and 25,000 VND/Government bond futures contract Some securities companies announced policies to reduce securities transaction fees to 0.1% such as VPS Securities Joint Stock Company (VPS), Vietnam Construction Securities Joint Stock Company (VNCS) Currently, the fee for underlying securities at VPS is 0.1%, the fee for derivatives transactions is only from 500 - 1000 VND/1 contract, VPS's margin interest rate is less than billion only 8%/1 year VPS is one of the securities companies with the cheapest transaction fees in Vietnam today c The brokerage department supports investment consulting of VPS If transaction fees are a factor investors need to consider, then the quality of the consulting broker is a matter of concern in terms of what support they receive when that broker advises them Securities accounts are usually managed by the brokerage department Investors can choose to trade themselves or receive advice, the fee for advice is usually higher However, for those coming to the market for the first time, this consultation is necessary Document continues below Discover more Securities from: analysis and… FIN08H Học viện Ngân hàng

have much experience, the advice of the stock brokerage department will help limit the risks somewhat Currently in the market, there is a VPS securities company that maintains the same transaction fees for accounts without consulting brokers and with consulting brokers (usually other companies will have higher fees when consulting broker) d Stock brokerage market share of VPS According to the latest update on stock brokerage market share, VPS, SSI, HCM, VND, and MSB securities companies have accounted for 65-70% of the stock brokerage market share of the entire market Just like a good, reputable product with a good price will be bought and used by many people and VPS is currently a securities company with a huge market share in Vietnam, the derivatives segment alone accounts for nearly 60% It is not natural that the VPS securities company has such a large stock brokerage market share VPS has good quality and a very good support consulting team, which makes many stock investors open accounts at VPS This Currently, VPS has the cheapest stock transaction fees in Vietnam e VPS software system Trading software systems and investment support services are also very important factors In today's transactions, all transactions are done over the internet The software system is not fast or good, which will hinder investors' ability to buy and sell Securities companies now have many investment support services, such as virtual stock trading software systems, software providing stock data, investment buying and selling recommendations, etc Advantages: VPS's software system is fast and stable even when the market is bad, the mobile interface is beautiful and modern, and there is a virtual derivatives trading system for new investors f Charter capital of VPS This is one of the very important criteria related to reputation and safety when customers consider the best place to open a stock account Normally, a securities company with a large charter capital will not only demonstrate the company owner's commitment to long-term sustainable operations, but also attract large cash flows and customers.VPS Securities Company is ranked in the top in terms of market capitalization, thus strengthening the long-term safety when entrusting your account to VPS Securities Company g Support opening EKYC securities accounts VPS Securities Company allows opening 100% online securities accounts using EKYC technology to authenticate account opening With just a few steps such as verifying signature and face the investor can open an account This helps all

transportation infrastructure, enhancing production capacity and providing high-quality products  Product diversity:offering various steel products, including coils, sheets, pipes, and value-added

production and export activities  Competition from Competitors: Fierce competition from steel industry rivals can pose a significant threat Analysis of the HSG Stock Trading Process After researching, referencing, and analyzing based on the knowledge we have learned, our group had decided to invest in HSG stock (Hoa Sen Group) Date 20/09/2023 02/10/2023 03/10/2023 Closing price 23.15 20.1 18.7 Change +/- 0.65% 0.50% -6.97% 21 Observing HSG stock prices from the beginning of September shows that the stock price has been uptrend The peak was the closing price on Sep 20th, which was 23 with a price fluctuation of (+5.50%) Between Sep 20th and Oct 2nd, the price dropped to 20.1 Our group made the decision to purchase 8.35 shares on the morning of Oct 3rd at a price of 19.55 The closing price on that day was 18.7 with a price fluctuation of (-6.97%) 22 Since the start of investment, HSG stock has been a strong downtrend trend, with continuous price fluctuations The lowest price was on Oct 26th, with a closing price of 16.6, price fluctuation of (-6.74%) However, from Oct 27th, our group noticed a slight uptrend in HSG stock price Therefore, our group decided to sell on Nov 1st to cut losses and manage risk during the investment period The profit at the end of the investment = Amount received upon selling - Amount deducted upon purchase = 141,595 - 163,485 = 21,890 (a loss of 13.39%) 23 IV Final settlement of account V Assessment of the group's investment outcomes Our group's fundamental and technical analysis processes have not been thorough, meticulous, and have many shortcomings due to incomplete deductive thinking and lack of experience in stock investment These are direct reasons leading to the group's ineffective decisions Another reason for the group's ineffective investment is the impact of economic market fluctuations on businesses: The stock market over the past nearly 10 months has been affected by many macroeconomic fluctuations both domestically and globally The context of heightened political tension and high inflation has forced many economies to tighten their monetary policies, causing the USD to appreciate, which has put pressure on the exchange rates of most countries With high openness, the Vietnamese economy is not immune to these impacts Many of Vietnam's trading partners experienced slow growth, even falling into recession, leading to a serious decline in imports and exports, as well as a slowdown in production activities Specifically for the steel industry: 24 • According to statistics from KIS Vietnam Securities Company, the total revenue of 24 listed steel companies in the second quarter of 2023 decreased by 27.7% compared to the same period last year and increased by only 0.3% compared to the first quarter of 2023, while the total post-tax profit (PAT) of the parent company in the second quarter of 2023 remained flat compared to the first quarter • Although the gross profit margin improved (from 5.5% to 7.4%) as the pressure of inventory costs disappeared and input costs remained low, half of the listed companies still incurred losses in the second quarter of 2023 • The third quarter of 2023 will be a challenging period for steel production companies as weak market demand due to the rainy season and declining prices will impact profitability, even though input costs are stable • Hoa Sen Group (HSG) reported a net profit of just over 14 billion VND in the third quarter of 2023 (the company's financial year runs from October to September 30), a significant decrease from the second quarter of 2023 when it reported a profit of 251 billion VND The reason for this is the sharp decrease in sales and financial revenues For the cumulative months, the company still incurred a net loss of 410 billion VND 25 Conclusion Through the process of stock investment in the HSG stock code, it has truly provided our group with valuable experience in stock market investment After all, investment involves bearing the risk of losses Following the philosophy of investor Warren Buffett, 'The most important investment you can make is in yourself.' In the market, people tend to be obsessed with seeking investment opportunities, often overlooking the opportunities for learning and knowledge enhancement The stock market is a 'buy-sell risk' market, so risk in the stock market is inevitable, and we can only mitigate the risk for each investment decision by improving our own capabilities Hence, our article on stock investment by our group comprises the investment process, the results of less effective business operations, with a crucial focus on identifying the reasons and the lessons learned by the group References Hoa Sen Joint stock company https://finance.vietstock.vn/HSG-ctcp-tap-doan-hoa-sen.htm Vietnam’s current economic situation https://www.gso.gov.vn/du-lieu-va-so-lieu-thong-ke/2023/09/bao-cao-tinh-hinhkinh-te-xa-hoi-quy-iii-va-9-thang-nam-2023/ Overview of Hoa Sen Group and history of formation and development https://hoasenjobs.com/trang-chu/trang-chu.35a515b1/vi Introduce VPS company and reasons for choosing to open account https://nududo.com/co-nen-mo-tai-khoan-chung-khoan-vps-hay-khong/ Securities market at the time of investment https://nhandan.vn/hnx-thang-9-nha-dau-tu-nuoc-ngoai-mua-rong-356-ty-dongpost775849.html Business update report 14/8/2023 – HSX: HSG https://www.bsc.com.vn/Report/ReportFile/4519315 Securities: ups and downs and expectation 2023 26 https://dantri.com.vn/kinh-doanh/chung-khoan-thang-tram-va-ky-vong-nam-202320231028054622850.htm Transaction price history of HSG https://s.cafef.vn/lich-su-giao-dich-hsg-1.chn Price list of VPS https://banggia.vps.com.vn/chung-khoan/HOSE 27
