Active small-cap funds often underperform midcap benchmarks, reveals analysis

A recent comparison highlights that many active small-cap mutual funds, despite promising high returns, struggle to outperform the relatively tougher Nifty Midcap 150 index, raising questions over their cost-effectiveness for long-term investors.

Active small-cap funds may still promise outsized returns, but a new comparison from Freefincal suggests that many investors are paying for a level of consistency that never really arrives. The analysis compares active small-cap mutual funds with the Nifty Midcap 150 index, arguing that the mid-cap benchmark is a tougher and more useful yardstick than a small-cap index because it is harder to beat and has often delivered stronger long-term returns. That approach also reflects a broader theme in fund research: size can matter, but so can cost, liquidity and the quality of the stocks a fund actually owns. Kiplinger’s recent guide to small-cap exchange-traded funds also notes that the segment can be attractive for long-term investors, though it stresses the importance of fund construction, fees and exposure to lower-quality companies.

Freefincal’s latest review focuses on rolling returns, a measure that shows how often a fund beats its benchmark over overlapping periods. In one example, Tata Small Cap Fund beat the Nifty Midcap 150 in 563 out of 698 five-year rolling periods, giving it an outperformance rate of 80.7% over the sample examined. But when the wider universe of direct-plan small-cap funds was tested against the same index, the results were far less convincing. Over three years, only eight of 22 funds met the author’s threshold for consistency; over four years the figure fell to six of 20, while over five years 11 of 20 qualified. The pattern broadly supports Freefincal’s long-running view that active managers often struggle to justify the higher charges attached to them.

The article also points out that the small-cap label can be misleading. Several schemes that sit in the small-cap category have historically held sizeable mid-cap positions, which can make their performance look better than a pure small-cap strategy would suggest. That matters because the comparison is not simply about whether a fund beats an index in a good year, but whether it does so often enough to justify the cost. Freefincal says that, even where active small-cap funds sometimes improve on mid-cap benchmarks, the advantage is not strong or durable enough to support the fees investors pay.

The broader conclusion is cautious rather than dogmatic. Freefincal says a mid-cap index fund may be a reasonable option for investors willing to take more risk than they would in a large-cap portfolio, but it stops short of fully endorsing it as a default choice. The concern is that mid-cap liquidity can dry up sharply in a market stress event, especially if assets under management become too large and trading becomes more difficult. That caveat sits alongside a more conventional model of portfolio construction: investors content with steadier, large-cap exposure can stay with Sensex, Nifty 50 or Nifty 100 index funds, while those seeking a little more growth potential may prefer a Nifty Next 50 fund.

For investors who want broad market exposure in one fund, Freefincal says the Nifty 500 is a practical compromise, though it still leans heavily towards large-cap names and should not be mistaken for a pure all-market portfolio. The underlying message is that past outperformance in active small-cap funds should not be confused with a dependable edge. In Freefincal’s reading of the data, that edge is too inconsistent to reward the higher expense of active management, especially when passive alternatives can provide simpler, cheaper exposure to equity risk.
