Sharpe 1963 single index model
Sharpe's single-index model including Expert Betas reflecting expert's knowledge and preferences modelled as fuzzy trapezoidal numbers instead of precise ones. Defined Expert Betas must have suitable features with respect to the quality and handling of information such that they can be incorporated in useful mathematical programming models. SHARPE’S SINGLE INDEX MODEL: THE THEORETICAL INSIGHT This simplified model proposes that the relationship between each pair of securities can indirectly be measured by comparing each security to a common factor ‘market performance index’ that is shared amongst all the securities. This is why the shrinkage estimator is a weighted average of the sample covariance matrix with Sharpe's (1963) single-index model estimator where the structure is determined by a shrinkage coefficient k as will be seen in a further section. OPTIMAL PORTFOLIO CONSTRUCTION USING SHARPE’S SINGLE INDEX MODEL - A STUDY OF SELECTED STOCKS FROM BSE Dr. R. Nalini* Abstract: To make wise decisions in investment, there is a need for knowledge on security analysis and portfolio management. A rational investor aims at attaining maximum return with minimum risk. 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. William Sharpe (1963) mengembangkan model yang disebut dengan model indeks tunggal (single-index model). Model ini dapat digunakan untuk menyederhankan perhitungan. disamping itu, model indeks tunggal dapat juga digunakan untuk menghitung return ekspektasi dan resiko portofolio.

Table 1 besides a Factor (Index) Models. • The first and simplest index model is the single– index model (SIM) proposed by Sharpe (1963). • This is based on the observation that, 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. an optimal portfolio by using Sharpe's Single index model for the period of April 2006 to December 2011 on daily return basis. selected out of 50 short listed scripts, giving the return of 0.116%.

Sharpe accepted Markowitz's suggestion that he investigate Portfolio Theory as a thesis project. By connecting a portfolio to a single risk factor, he greatly simplified dissertation, published in 1963 as "A Simplified Model of Portfolio Analysis.
