1 BUILDING SHARPE OPTIMIZATION STOCK PORTFOLIOS AND PERFORMANCE ANALYSIS

2 SCOPE OF PRESENTATION INTRODUCTION SHARPE RATIO & OTHER PERFORMANCE MEASURES COMPARING PERFORMANCE MEASURES METHODOLOGY ADOPTED CONCLUSION RECOMMENDATIONS

3 NEED FOR PERFORMANCE ANALYSIS MUTUAL FUNDS THE MOST APPROPRIATE OPPORTUNITY FOR SMALL INVESTORS AS FINANCIAL MARKETS BECOME MORE COMPLEX & SOPHISTICATED, INVESTORS NEED A FINANCIAL INTERMEDIARY MODELS LIKE SHARPE PROVIDE PROFESSIONAL EXPERTISE ON SUCCESFUL INVESTING

4 13-4 SHARPE RATIO The Sharpe ratio is a reward-to-risk ratio that focuses on total risk. It is computed as a portfolios risk premium divided by the standard deviation for the portfolios return.

5 SHARPE RATIO FOR A LAYMAN IT QUANTIFIES THE RISK EFFICIENCY OF AN INVESTMENT EQUAL TO EFFECTIVE RETURN(ACTUAL RETURN MINUS RISK FREE RATE) OF AN INVESTMENT DIVIDED BY STANDARD DEVIATION A HIGH SHARPE RATIO SIGNALS AN INVESTMENT WITH GREATER RISK EFFICIENCY AND IS DESIRABLE

6 13-6 OTHER PERFORMANCE MEASURES The Treynor Ratio The Treynor ratio is a reward-to-risk ratio that looks at systematic risk only. It is computed as a portfolios risk premium divided by the portfolios beta coefficient.

7 13-7 OTHER PERFORMANCE MEASURES Jensens Alpha Jensens alpha is the excess return above or below the security market line. It can be interpreted as a measure of how much the portfolio beat the market. It is computed as the raw portfolio return less the expected portfolio return as predicted by the CAPM. Actual return CAPM Risk-Adjusted Predicted Return Extra Return

8 13-8 Comparing Performance Measures, I. Because the performance rankings can be substantially different, which performance measure should we use? Sharpe ratio: Appropriate for the evaluation of an entire portfolio. Penalizes a portfolio for being undiversified, because in general, total risk systematic risk only for relatively well-diversified portfolios.

9 13-9 Comparing Performance Measures, II. Treynor ratio and Jensens alpha: Appropriate for the evaluation of securities or portfolios for possible inclusion into an existing portfolio. Both are similar, the only difference is that the Treynor ratio standardizes returns, including excess returns, relative to beta. Both require a beta estimate (and betas from different sources can differ a lot).

10 13-10 Sharpe-Optimal Portfolios, I. Allocating funds to achieve the highest possible Sharpe ratio is said to be Sharpe-optimal. To find the Sharpe-optimal portfolio, first look at the plot of the possible risk-return possibilities, i.e., the investment opportunity set. Expected Return Standard deviation × × × × × × × × × × × × × × × ×

11 13-11 Expected Return Standard deviation × A RfRf Sharpe-Optimal Portfolios, II. The slope of a straight line drawn from the risk-free rate to where the portfolio plots gives the Sharpe ratio for that portfolio. The portfolio with the steepest slope is the Sharpe-optimal portfolio.

12 13-12 Sharpe-Optimal Portfolios, III.

13 METHODOLOGY ADOPTED CALCULATION OF ALL THE COMPOSITE PERFORMANCE MEASUREMENT RATIOS RANKING THE SELECTED 24 MUTUAL FUNDS AS PER THE RATIOS OBTAINED APPLICATION OF SHARPE OPTIMIZATION TECHNIQUE TO KOTAK 30 EQUITY GROWTH MUTUAL FUND

14 RANKING OF SAMPLE MUTUAL FUNDS ON BASIS OF TREYNOR RATIO

15

16 RANKING OF SAMPLE MUTUAL FUNDS ON BASIS OF JENSON RATIO

17 RANKING OF SAMPLE MUTUAL FUNDS ON BASIS OF SHARPE RATIO

18 ORIGINAL ASSET ALLOCATION FOR KOTAK 30 GROWTH SCHEME

19 RESULTS OF SHARPE OPTIMISATION FOR KOTAK 30 GROWTH SCHEME

20 CONCLUSION SHARPE RATIO IS A BLUNT INSTRUMENT TO MEASURE RISK ADJUSTED RETURN IT PRESENTS A MORE COMPLETE PICTURE OF FUND PEFORMANCE THAN RAW RETURN IT HELPS INVESTORS EVALUATE RELATIVE SUCCESS OF COMPETING FUNDS FOLLOWING THE SAME BROAD INVESTMENT STRATEGIES

21 RECOMMENDATIONS WELL KNOWN PORTFOLIOS CAN HAVE IMPROPER DESIGNS TOO A GOOD FUND MANAGER SHOULD NOT RELY ON A SINGLE MEASURE FOR DESIGNING A PORTFOLIO FINALLY,EVALUATION OF A FUND MANAGER SHOULD BE DONE MANY TIMES OVER DIFFERENT MARKET ENVIRONMENT

22 13-22 It is not the return on my investment that I am concerned about. It is the return of my investment! – Will Rogers
