Need for Sharpe Model: Need for Sharpe Model In Markowitz model a number of co-variances have to be estimated. If a financial institution buys 150 stocks, it has to estimate 11,175 i.e. , (N 2 – N)/2 correlation co-efficients. Sharpe assumed that the return of a security is linearly related to a single index like the market index.

Single Index Model Casual observation of the stock prices over a period of time reveals that most of the stock prices move with the market index. When the Sensex increases, stock prices also tend to increase and vice – versa. This indicates that some underlying factors affect the market index as well as the stock prices. 4.

To get an insight into the idea embedded in Sharpe’s Single Index Model. 2. To construct an optimal portfolio empirically using the Sharpe’s Single Index Model. 3. To determine return and risk of the optimal portfolio constructed by using Single-Index Model and the Capital Asset Pricing Model. The alpha of a portfolio is the average of the alphas of the individual securities. For a large portfolio the average will be zero, since some stocks will have positive alpha whereas others will have negative alpha. Hence, the alpha for a market index will be zero. { Single Index Model (Review) { Multi Index Models { Capital Asset Pricing Model 1 The Single Index Model (Review) One possible model for the returns is R i = i + iR m + i where i,and i are constants, R m is the return of a market index and i is a random variable with mean 0 and variance ˝2 i.
