We discuss the performance consistency of actively managed mid cap funds by comparing them with the Nifty Midcap 150 index. This is the Aug 2026 report.

Reward measure: Rolling returns outperformance consistency.
Rolling returns are a simple estimate of how consistently a fund has outperformed a benchmark. Take, for example, the Tata Midcap Fund – Growth – Direct Plan vs Nifty Midcap 150 (graph below) between January 1, 2013, and Aug 21, 2026. There are 2124 5-year rolling returns. If we plot the return for each duration for the fund and index together, we get a graph like this.
The fund outperformed the index only 886 out of 2124 times. Thus, rolling-return outperformance consistency over seven years is 886/2124 = 41.71%, indicating poor performance. A consistent performer should beat the index at least 60% to 70% of the time. So, the more consistent the rolling-return outperformance, the better.

Given the high fees AMCs charge, we expect 70% performance consistency. If they fail, then they do not deserve such high fees. We are better off with an index fund.

So, can we invest in a Nifty Midcap 150 index fund?
For most investors who desire “some” midcap and small cap exposure, a Nifty 500 index fund is the best choice. However, they should appreciate that it is a large-cap-oriented index, and its outperformance vs the Nifty 50 or Nifty 100 will be periodic.
For those who want dedicated midcap stock exposure, our traditional recommendation is Nifty Next 50. However, we must consider whether it is becoming more of a large-cap-like fund due to higher market participation. See: Nifty vs Nifty Next 50 vs Nifty Midcap 150 vs Nifty Smallcap 250: Return Comparison Aug 2026.
The only thing stopping me from recommending a Midcap index fund is that it hasn’t seen an abrupt crash so far when its liquidity suddenly evaporates. How the fund manager would cope then, especially when AUM swells, remains to be seen. So for now, I’m sticking to my Nifty Next 50 index fund recommendation for those who want a “bit more” than the Nifty 50.
