Appliaction of CAPM model: a case study on utility industry

The Capital Asset Pricing Model established by Sharpe (1964) and Lintner (1965) specifies that expected return on a particular stock is developed by considering the risk premium and risk free interest rate. Early practical analysis of different models have supported the main prediction that beta is the sole explanatory factor, which tends to explain the cross-sectional variation in stock. It is observed in recent empirical tests that the asset pricing model comprise a number of variables, which helps in explaining cross-sectional variations in stock returns, apart from the market risk. The model had initiated the idea of asset pricing theory (Roll, 1997). Prior to that, there was no asset pricing models and the same was generated by considering the nature and taste of investment opportunities available in the stock market. The model clearly tested predictions that are made with respect to return and risk of the stock. The models are used presently for estimating cost of equity and examining performance of portfolios that are developed in the stock market. It states that there is always a linear relation between expected return of a stock, risk associated with the stock and beta. Here, beta is defined as the variable, which focuses on explaining the cross-sectional return of stocks. The model was initially devised by Harry Markowitz. However, it was later modified by Sharpe and Lintner. Initially, the model explained that if an investor is selecting a particular portfolio for a particular period of time and receiving a return, he is risk averse. The model is based on algebraic statement, which predicts the relation between risk and return of the portfolio. The modified version of Sharpe (1964) and Lintner (1965) has the following assumptions:
