Smallcap mutual funds attract 44% of equity inflows despite stretched valuations. Should investors be cautious?

Small and mid-cap mutual funds attracted the largest share of equity fund inflows in September, accounting for nearly half of the Rs 38,307 crore in net inflows into equity funds. Despite expensive valuations relative to large caps, investors continue to pour money into these smaller segments.

The Smallcap 250 index's forward price-to-earnings multiple fell only slightly from 25 times to 23.6 times between September 2024 and 2026, while the Nifty 50's multiple dropped more substantially from 24.8 times to 17.6 times. This indicates that small caps remain considerably more expensive than large ones, with a 34% premium versus a historical average of 11% and a 47% premium for mid caps versus a 19% average.

Comparing these valuations to post-market peaks in 2007, 2010 and 2017 shows that small caps underperformed large caps by about 30% over the next two years. While past performance does not predict the future, it highlights the risks of investing in expensive small and mid-cap stocks.

The report advises investors to favor large-cap funds as the core of their portfolios while being more selective with mid and small caps. It suggests active management over passive exposure in these segments.

Investors need to consider whether recent valuations make smaller stocks truly attractive given their earnings prospects. A price decline does not automatically mean a stock is a good value if its fundamentals or future earnings growth do not justify the lower multiple.

The disconnect between fund flows and relative valuations warrants close monitoring. If investors keep piling into the more expensive small and mid-cap segments, the market could become vulnerable to earnings disappointments or shifts in risk appetite.
