According to a comprehensive analysis by Otto Money's Apurv Gupta, the debate between active and passive investing shows no clear winner across all categories. The study analyzed monthly rolling three-, five-, and seven-year periods from January 2013, covering active direct-growth equity funds across seven categories and approximately 44,500 fund-window observations. Each active fund was compared with its benchmark after deducting 0.20% annually from the benchmark return to account for index fund costs. The findings suggest that choice depends on the market segment, the fund selected, and the costs involved, with active funds outperforming their benchmarks in only 30% to 52% of rolling periods across all categories analyzed.
Passive funds demonstrate superior performance in segments with narrower stock universes and well-researched companies. In large-cap, mid-cap and large & mid-cap categories, active funds beat their benchmarks in only 30% to 52% of monthly rolling periods. These segments feature a smaller pool of widely followed stocks with thousands of analysts tracking them, making it harder for active managers to consistently find opportunities to beat the index. For investors, this makes index funds a strong option for the large- and mid-cap core of a portfolio, particularly when keeping investment costs low is a priority.
The performance landscape changes significantly in broader, less researched investment universes. Active funds outperformed in 57% to 65% of rolling periods in flexi-cap, focused, and value categories, though the median advantage remained less than 1% annually. Small-cap funds were the clear standout, beating their benchmark in 90% of the time over a 7-year horizon. This superior performance in small-cap segments reflects where the stock universe is broader and research coverage can be less extensive, historically providing investors with a much higher probability of finding active funds that add value. The broader stock universe and relatively lower research coverage in this segment may provide fund managers with more opportunities to generate alpha through stock selection.
The overall category success rates mask significant differences between individual funds, with fund selection adding another layer of risk. In seven-year periods, the flexi-cap fund at the 5th percentile underperformed its benchmark by 4.3%, while the 95th-percentile fund outperformed it by 5.8%. This represents roughly a 10-percentage-point gap compared with the median active advantage of just 0.6% annually. Regular plans reduce active fund benefits significantly: flexi-cap funds beat benchmarks in 63% of seven-year windows for direct plans versus 47% for regular plans, while small-cap funds achieved 90% versus 78% respectively. Costs also have a significant impact on outcomes: in large-cap funds, active direct plans outperformed in 30% of seven-year windows compared to 11% for regular plans, while mid-cap funds showed 46% versus 28% respectively.
The analysis provides clear guidance for investors navigating the active-passive debate. Use index funds for the large- and mid-cap core of the portfolio due to their superior performance in these segments, particularly when keeping costs low is a priority. Consider active funds where the stock universe is broader, particularly small-caps, where the research coverage can be less extensive and active management has historically shown a higher probability of adding value. Choose funds carefully, as the difference between a good and poor active fund can be much larger than the average advantage of active investing. Prefer direct plans for active funds, as commissions can cost more than the average manager adds, with the exception of small-cap funds where index funds may be more cost-effective. Fund selection remains critical because individual active fund performance varies significantly, even within strong categories, with the difference between a strong and weak active fund potentially substantially larger than the average advantage of active management.
