| Popis: | This research study analyzes the variation in monthly returns of securities for companies listed in Pakistan Stock Exchange-PSX (Formerly known as KSE). The Capital Asset Pricing Model (CAPM) of SLB has provided a method for researchers and experts to forecast the risks and returns. The main purpose of CAPM is to estimate beta of security to explain how much security is aligned or sensitive with the movement or changes in the market return. The research is conducted by means of monthly market capitalization of companies; portfolios are formed and the role of idiosyncratic risk in explaining the variations in the stock returns have been studied. With the same portfolios, the relationship of risk and return relationship has also been analyzed. This empirical analysis is conducted for the period of May 2010 - April 2014. Data analysis reveal that the idiosyncratic risk is a significant factor in explaining the stock returns. Capital Asset Pricing model is rejected in this study context because of positive and significant intercept in all portfolios. The research findings strongly support Chan and Chui (1996) and Strong and Xu (1997), assertions that the relationship between beta and security returns is weak. Therefore, CAPM is an empirically anemic model to be used in the Pakistani market. |
