Take all diversified equity mutual fund schemes. Find out how they fared over various time periods. Crunch the numbers. Put them against the market benchmark, the BSE Sensex. What do you get? A rather uninspiring look at fund managers, experts who we pay about 2.5 per cent of our investment to outperform markets. Take a look: • During the past month, when the Sensex crashed by 25.4 per cent, the average fall in 158 diversified equity funds was 28.9 per cent—an underperformance of 3.4 percentage points. Only one out of 10 funds managed to beat the Sensex in this period. • In the past two weeks, when the Sensex fell by 12.8 per cent, the funds on an average, fell by 16.6 per cent, an underperformance of 3.8 percentage points, with just 16 of 161 funds being able to beat the Sensex. In other words, just 9.9 per cent of funds were able to deliver returns better than the Sensex. • A study of 161 diversified mutual funds over the past week, two weeks, one month, three months, six months, 12 months and 36 months shows that on an average the funds have been lagging the Sensex in all but the 36-month period. The level of underperformance is worrying—the funds have lagged the Sensex by between 3.5 percentage points (in the one month period) to 8.7 percentage points (12 months). The margin of underperformance is wide. This means investors would have been better off with index funds, which essentially replicate the movements of indices they track. But it is not merely the level but the extent of underperformance that’s disturbing. Barring 36-month comparisons, in all other time frames, the percentage of funds that has lagged the Sensex has ranged from 74.6 per cent for 12-month performance to 96.3 per cent over one week—which means more than nine out of 10 funds delivered below benchmark returns.
