A Study on Performance Evaluation of Selected Mid Cap Mutual Funds in India: An Analysis of Historic Returns, Risk Ratios, and SIP Returns

This study set out to evaluate the performance of selected mid cap mutual fund schemes in India using historic returns, risk ratios, and SIP returns data. The analysis confirms that mid cap funds, as a category, have delivered attractive risk-adjusted returns over the study period, with the average scheme rewarding investors with more than one unit of excess return per unit of risk taken (mean Sharpe Ratio of 1.19). More importantly, the study demonstrates that risk-adjusted measures — particularly the Sharpe Ratio and Treynor's Ratio — are considerably more informative than raw volatility or beta for identifying funds likely to deliver superior returns, since raw risk measures explained only a small fraction of return variation in this sample. The consistent outperformance of Direct Plans over Regular Plans, without any corresponding increase in risk, reinforces a now well-established finding in the literature: cost matters, and the choice between Direct and Regular plans is primarily an economic decision about distribution cost rather than a risk-return trade-off. For investors comfortable conducting their own research, Direct Plans represent a straightforward, no-additional-risk route to higher net returns; for those requiring advisory support, the incremental cost of a Regular Plan should be weighed consciously against the quantifiable long-term return drag it entails. The strong association observed between CRISIL ratings and both return and risk-adjusted performance suggests that such third-party ratings, despite their limitations, remain a reasonably reliable starting point for retail investors who lack the time or expertise to compute Sharpe, Treynor, and Jensen measures independently. However, the wide dispersion of performance even within similarly rated funds indicates that ratings should complement, rather than replace, a fuller risk-adjusted evaluation of the kind undertaken in this paper. Overall, the study reaffirms the enduring relevance of Modern Portfolio Theory-based performance measures — over sixty years after Markowitz (1952), Sharpe (1964, 1966), Treynor (1965), and Jensen (1968) first proposed them — for evaluating actively managed equity mutual funds in a rapidly growing but still-maturing market like India. As SIP participation continues to expand across smaller cities and lower-ticket-size investors, continued, updated empirical evaluation of fund categories such as mid cap funds will remain essential to protecting and enhancing retail investor outcomes.
