8.2 Single-Index Model The major assumption of Sharpe's single-index model is that all the covariation of security returns can be explained by a single factor. This factor is called the index, hence the name "single-index model."

Sharpe assumed that the return of a security is linearly related to a single index like the market index. 3. 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. Sharpe's single-index model was applied by using the monthly closing prices of 10 companies listed in NSE and CNX BANK pr ice index for the period from For a description of its more general application in semiparametric regression, see Semiparametric regression. The single-index model (SIM) is a simple asset pricing model to measure both the risk and the return of a stock. The model has been developed by William Sharpe in 1963 and is commonly used in the finance industry. are not effective for large , so William Sharpe developed model known as the Single Index Model to simplify the Model is based on the observation that the price of a securities fluctuates in the direction of the market price index. In general, if the stock price index rises then the stock price also rises, and According to Markowitz, a portfolio of 100 securities would require the following bits of information: 100 (100 + 3)/2 = 5150, and Markowitz covariance shows that 100 securities would require (N 2 – N)/2 = (100 2 – 100)/2 = 9900/2 or 4950 covariance. Sharpe first made a single index model. chaotic situations the Sharpe's Single Index model may be used to construct an optimal portfolio. This helps the investor to find a portfolio that best suits his needs. The present study is undertaken to prove that by applying this model an individual can construct a portfolio with maximum return for a given level of risk.
