sector index INTRODUCTION 1.1 Research problem One of the most widely used tools to track industry or sector performance in the securities market is sector indices These are the essential tools for investors to follow up sector movements as well as to see the trend in those movements However, the securities market of Vietnam still lacks of an comprehensive and effective sector indices tools since the official market indices of the securities market of Vietnam (VN-Index and HASTC-Index) are to measure the overall market performance rather than any particular sector This thesis ―A study on sector index of stock market and proposal for development of FPTS sector index‖ is aimed at give out a detailed proposal for the development of FPTS sector indices 1.2 Objectives &Aims 1.2.1 Objectives  Study sector index definitions  Study sector index application and calculation methodology  Compare and analyze most known international and local sector indices 1.2.2 Aims Give out detailed proposals for the development of FPTS sector index family A study on sector index of stock market - proposal for development of FPTS sector index 1.3 Research question: In order to achieve the objectives of the thesis, the author of thesis will try to answer the following questions:  What are definition, types and applications of sector indices?  What are the calculation methods of sector indices?  What are the most known international and local sector indices? What are the differences and similarities among them?  How to select members of FPTS sector indices?  How to calculate FPTS sector indices?  What are the core FPTS sector back-end functionalities and frond-end interfaces (user requirement description)? 1.4 Method/Approaches  Empirical method  Approaches: statistics 1.5 Scope of work This thesis study most widely mentioned sector indices (both international and local) by the time of finishing this thesis (August, 2008) 1.6 Data resources Data and material for this study will be taken from different sources as following:  Database and working papers from FPTS analyst department A study on sector index of stock market - proposal for development of FPTS sector index The market capitalization of component stocks in the index is affected by a variety of corporate actions, such as dividend payment, rights offering, merger and acquisition The addition and deletion of a stock in sector indices also affect the index value Therefore, in all cases when index value changes due to changes in index composition or corporate actions, divisor adjustments are required so as to maintain index continuity The divisor adjustment rule is to equalize the index value before and after the event The following formula is used for divisor adjustment: Where t+1: event date Dt: divisor at time (t) Dt+1: divisor at time (t+1) This divisor is calculated in the database after the market closes on date (t) Mt: total market capitalization at time t of all the stocks in the index Mt+1 estimated: total market capitalization at time (t+1), estimated based on closing prices of component stocks on date t (adjusted using the formulas in section 1.3.3.2 Divisor adjustment formula on page 16) and number of outstanding shares on date t (adjusted using the formulas in section 1.3.3.2 Divisor adjustment formula on page 16) 3.2.5 Data sources Stock trading statistics (including prices, number of outstanding shares, trading volumes) are obtained directly from Ho Chi Minh Stock Exchange (HOSE) and Hanoi Securities Trading Centre (HASTC) 57 A study on sector index of stock market - proposal for development of FPTS sector index Other information related to listed companies used for FPTS sector index calculation (such as information on rights exercise) is taken from official and reliable sources such as the State Securities Commission, HOSE, HASTC and listed companies The information is consolidated on FPTS’s online information gateway EzSearch FPTS sector index committee will employ all resources and measures with best efforts to ensure the accuracy, completeness and timeliness of input data used in FPTS sector index calculation All errors in input data or in FPTS sector index construction methodology (if any) will be informed immediately after being detected, accompanied by reasons for errors 3.3 Index memberships 3.3.1 Index eligibilities To be eligible for inclusion in FPTS sector indices, stocks must meet the following criteria arranged by their priority level: Listing venue: The stocks must be listed on Ho Chi Minh Stock Exchange (HOSE) or Hanoi Securities Trading Centre (HASTC) Stock count: Each sector index must have a minimum of constituents If there are fewer than stocks in a sector, this sector index will include all stocks in the sector Liquidity: Constituents must have a liquidity ratio – defined by total trading volume over the previous 12 months divided by average number of outstanding shares over the previous 12 months – at least 20% For stocks that not have 12 months of trading history (for example, newly listed stocks), we use annualized trading volume 58 A study on sector index of stock market - proposal for development of FPTS sector index Market capitalization: Stocks that meet the liquidity threshold are included in the sector index in order of their market capitalization until the total cumulative market capitalization of these stocks reaches 80% of the total market capitalization of the entire sector Stocks with market capitalization reaching at least 10% of the total market capitalization of the entire sector will be included in the corresponding sector index, without regards to their liquidity ratios The following securities are not eligible for inclusion in FPTS sector indices:  OTC-traded securities  Preferred stocks  Derivative securities and closed-end funds  Securities which experience considerable structural changes or are subjects of M&A, divestiture or spin-offs or bankruptcy 3.3.2 Additions to and deletions from FPTS sector indices Additions to and deletions from FPTS sector indices are done quarterly, specifically at the last trading day of March, June, September and December each year Updated information will be announced in one week as the latest on FPTS’s website and in our quarterly reports 3.3.2.1 Additions to FPTS sector indices FPTS index committee will consider additions to FPTS sector indices quarterly, based on this methodology guide as well as judgment for certain cases FPTS index committee will announce reasons for additions to FPTS sector indices 59 A study on sector index of stock market - proposal for development of FPTS sector index To be eligible as additions to FPTS sector indices at each quarterly index reconstitution date, a stock must meet the following criteria:  The stock is recently listed in the quarter and had a minimum of trading months or the stock is not included in FPTS sector indices at prior quarterly index reconstitution dates, and  The stock meets all stock selection criteria 3.3.2.2 Deletions from FPTS sector indices FPTS index committee will consider deletions from FPTS sector indices quarterly, based on this methodology guide as well as judgment for certain cases FPTS index committee will announce reasons for deletions from FPTS sector indices A stock in FPTS sector indices will be considered for being deleted from the indices when it violates any of the criteria for inclusion in FPTS sector indices 60 A study on sector index of stock market -

proposal for development of FPTS sector index CONCLUSION The securities market of Vietnam from October 2007 to June 2008 suffered from one of the most severe plunge in its history with a slash of 2/3 value from over 1100 to 366 point However, together with the Vietnamese dynamic and active economy, the long-term growth of the securities market of Vietnam is strong and determined To able to tap into market opportunities as well as avoid risk, investors should be equipped with effective and strong tools FPTS sector indices will be a tool of that kind With this thesis I hope that I have provided reader with some light on the nature and characteristics of indices and sector indices in particular, deep analysis on the current most notable international and domestics sector indices and a detailed prototype of a new, comprehensive sector indices which can be beneficial for individuals who want to study more about this subject as well as for organizations who want to develop an index for their own Implications for further research Further study can also be carried out to adjust and fine-tune the backend functions and front-end user interface and functions after the official launch of FPTS sector indices and receiving the feedback from the customers 67 A study on sector index of stock market -
