Reprinted fromThe Journal of Portfolio Management, Fall 1994 Other authors have termed the original version the Sharpe Index (Radcliff [1990, p. [1982] describe the use of benchmarks based on factor loadings from a multifactor model.
Sharpe Ratio Formula – Example #2. Here, one investor is holding $5,00,000 invested portfolio with an expected rate of return of 12%, and volatility of 10%. The efficient portfolio expects a return above 17% and volatility of 12%. The risk-free interest is 4%. A SIMPLIFIED MODEL FOR PORTFOLIO ANALYSIS 281 this method is related to the following factors: 1. The number of securities analyzed This will affect the extent of the computation in step (2) and the number of computations in step (3). 2. The number of corner portfolios Steps (2) through (5) must be repeated once to find each corner port- The Sharpe Ratio. (Your Name) has sent you a message from The Journal of Portfolio Management. (Your Name) thought you would like to see the The Journal of Portfolio Management web site. The higher the Sharpe Ratio, the better the portfolio or fund has performed in proportion to the risk taken by it. Sharpe ratio = (Average Portfolio Returns – Risk-Free rate)/Standard Deviation of Portfolio. If the Sharpe ratio of a portfolio is 1.3 per annum, it implies 1.3% excess returns for 1% volatility. Portfolio management helps an individual to decide where and how to invest his hard earned money for guaranteed returns in the future. Portfolio Management Models. Capital Asset Pricing Model. Capital Asset Pricing Model also abbreviated as CAPM was proposed by Jack Treynor, William Sharpe, John Lintner and Jan Mossin.
Optimal Portfolio of Sharpe Model: This optimal portfolio of Sharpe is called the Single Index Model. The optimal portfolio is directly related to the Beta. If Ri is expected return on stock i and Rf is Risk free Rate, then the excess return = Ri – Rf This has to be adjusted to Bi, namely,
2 Oct 2017 The Sharpe ratio is a measure of a portfolio's efficiency. In investing, you can combine investments in such a way to increase your return and 31 Mar 2017 Single Index Model and Sharpe index, Treynor index and Jensen index as analysis tool in the System of Stock Investment Decision Making. 28 Jun 2012 The comparative analysis was based on performance indicators, such as the Sharpe ratio and the Alpha and Beta parameters, and on a ratio of Optimal Portfolio of Sharpe Model: This optimal portfolio of Sharpe is called the Single Index Model. The optimal portfolio is directly related to the Beta. If Ri is expected return on stock i and Rf is Risk free Rate, then the excess return = Ri – Rf This has to be adjusted to Bi, namely, embedded in Sharpe’s Single Index Model, to construct an optimal portfolio empirically using the Sharpe’s Single Index Model, to determine return and risk of the optimal portfolio constructed by using Sharpe’s Single Index Model. Select the optimal portfolio using the Sharpe’s Single Index Portfolio Selection method. Assume the risk free rate of return as 5 per cent and the standard deviation of the market return as 25 per cent. Solution: The selection of the portfolio from these securities will be by building the following table. The table ranks the securities on the basis of the Sharpe measure of excess returns relative to beta risk:

Optimal Portfolio of Sharpe Model: This optimal portfolio of Sharpe is called the Single Index Model. The optimal portfolio is directly related to the Beta.

Select the optimal portfolio using the Sharpe’s Single Index Portfolio Selection method. Assume the risk free rate of return as 5 per cent and the standard deviation of the market return as 25 per cent. Solution: The selection of the portfolio from these securities will be by building the following table. The table ranks the securities on the basis of the Sharpe measure of excess returns relative to beta risk: 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. 3. sharpe index model 1. PORTFOLIO MANAGEMENT 2. INTRODUCTION The investor like to purchase securities with low risk and high return. Now for that purpose Markowitz model is good but we have to make lots of calculations in order to get the result. In Markowitz model we need N(N+2)/2 bits of information whereas in Sharpe 3N+2 bits of information is needed. 3. Sharpe Ratio Formula – Example #2. Here, one investor is holding $5,00,000 invested portfolio with an expected rate of return of 12%, and volatility of 10%. The efficient portfolio expects a return above 17% and volatility of 12%. The risk-free interest is 4%.
Intuitively, it can be inferred that the Sharpe ratio of a risk-free asset is zero. Portfolio diversification with assets having low to negative correlation tends to reduce is a Sharpe ratio of 0.45 for the base-case that, under the assumption of the single-index model for Sharpe, W. “A Simplified Model for Portfolio Analysis.”. are known as asset management companies. It is the most suitable Step2: For applying Sharpe's Single Index Model Ri, Rm, σei2, σp2, Rf, β values are Measuring portfolio return and risk under Single Index Model. Multi-Index Model work on portfolio analysis described in 1952 Journal of Finance article and Sharpe model would requires only N measures of beta coefficients. Measuring Heuristic Optimization of Portfolio Considering Sharpe's Single Index Model: An Portfolio management faces another problem related to the selection of weight Sharpe single index model to construct optimal portfolio and Security analysis were conducted before constructing an optimal portfolio which included the
