Title: Relevance of Capital Asset Pricing Model – A Review
Abstract: Though it is commonly said that higher the risk higher would be the returns, the questions that remain are, what type of risks are awarded and what is risk premium per unit of risk. A few equilibrium asset-pricing models attempted to answer these questions. Out of these, Capital Asset Pricing Model (CAPM) is the most popular and widely used model. It was independently developed by Sharpe (1964), Lintner (1965), and Mossin (1966). Fama (1968), Black, Jensen and Scholes (1972), Fama and Mac Beth (1973), and Fama and French (1992) and others proposed further refinements. The CAPM provides a precise prediction of the relationship between the risk of an asset and its expected return. In the Indian stock market the empirical studies on CAPM showed mixed results. Roll’s critique has attracted attention of many researchers and resulted in popular articles such as “Is Beta Dead?” “Is Beta Dead or Alive?” “Are Reports of Beta’s Death Premature? “Is Beta Dead Again?” that effectively reduced the popularity of CAPM in the world of finance in 1992. The debate regarding superiority of Asset Pricing Theory (APT) to CAPM is continuing. The empirical testing of APT is still in its early stage and concrete results in favour of APT or against CAPM do not exist. Till then, CAPM is expected to dominate the capital market as a measure to ascertain expected returns of risky securities.
