INTRODUCTION TO THE STUDY
Abstract
The study was carried at Share Khan, Coimbatore during March 2014. The aim of the study is to construct an optimum equity portfolio with stocks that form a part of the S&P BSE SENSEX (S&P Bombay Stock Exchange Sensitive Index), using Sharpe’s Single Index model. Daily close price of all the 30 securities of BSE Sensex for the period of 1 year from January 2013 to December 2013 is taken for analysis. In this model the securities ' inclusion in the portfolio is directly related to its excess return-to-beta ratio. Then they are ranked from highest to lowest order. The number of securities selected depends on a unique Cut- off rate such that all securities with higher ratios will be included. Percentage of investment in each of the selected security is then decided on the basis of respective weights assigned to each security.
Investments
Investment refers to an asset or item that is purchased with the hope that it will generate income or appreciate in the future. In an economic sense, an investment is the purchase of goods that are not consumed today but are used in the future to create wealth. In finance, an investment is a monetary asset purchased with the idea that the asset will provide income in the future or appreciate and be sold at a higher price.
Equity market investments typically yield high returns, particularly if invested over longer periods of time, although such investments are characterized by a high degree of price volatility in the short term.
