Subtopics: The Single-Index Sharpe Model has simplified this process by relating the return in a security to a single Market index. Firstly, this will theoretically reflect all well traded securities This can be achieved with the help of single index. (beta) model proposed by Sharpe. Markowitz Portfolio Theory. In the early 1950s, the investment community

A Study on Usage of Sharpe’s Single Index Model In Portfolio Construction With Reference To Cnx Nifty

Single-index model. A model of stock returns that decomposes influences on returns into a systematic factor, as measured by the return on the broad market index, and firm specific factors. Advantages & Disadvantages of Using Sharpe Ratio by Hunkar Ozyasar & Reviewed by Ashley Donohoe, MBA - Updated May 23, 2019 The Sharpe ratio, originally devised in the 1960s, essentially tells you if the potential return expected from an investment justifies the risks involved. A Study on Usage of Sharpe’s Single Index Model In Portfolio Construction With Reference To Cnx Nifty

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.

When the Sensex increases, stock prices also tend to increase and vice – versa. 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. Mathematically the SIM is expressed as: − = + (−) + ∼ (,) where: r it is return to stock i in period t r f is the risk free rate (i.e. the interest rate on treasury bills) ADVERTISEMENTS: Markowitz Model had serious practical limitations due to the rigours involved in compiling the expected returns, standard deviation, variance, covariance of each security to every other security in the portfolio.

Since William Sharpe's creation of the Sharpe ratio in 1966, it has been one of the most referenced risk/return measures used in finance, and much of this popularity is attributed to its

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. Mathematically the SIM is expressed as: Sharpe Ratio: The Sharpe ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return, the Sharpe’s Single Index Model and its Application Portfolio Construction 513 1. 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 Sharpe first made a single index model. This was compared to multiple index models for conducting reliability test in finding out the full variance efficient frontier of Markowitz. Many researchers have taken into consideration the Sharpe Index Models. They have preferred the stock price index to the economic indexes in finding out the full Sharpe’s SINGLE INDEX MODEL The model has been generated by “WILLIAM SHARPE” in 1963. The Single Index Model is a simplified analysis of “PORTFOLIO SELECTION MODEL” To measure both Risk and Return on the stock. • The SINGLE INDEX MODEL greatly reduces the number of calculations that would otherwise have to be made for a large Sharpe’s single index model will reduce the market related risk and maximize the returns for a given level of risk. Sharpe’s model will take into consideration the total risk of portfolio. The total risk consists of both systematic and unsystematic risk. The risk may be eliminated by diversification.
