Small-Cap Fund
A small-cap fund invests at least 65% of its assets in companies ranked 251st and below by full market capitalisation — smaller, often under-researched businesses.
A small-cap fund is built around the bottom of India's listed universe by size. Under SEBI's classification, large-caps are the top 100 companies by full market capitalisation, mid-caps are ranked 101 to 250, and small-caps are everyone ranked 251st and below.
How the Rules Work
A small-cap fund must keep at least 65% of its assets in equity of these small-cap companies. The rankings are not static: AMFI revises the market-cap buckets twice a year, using average full market capitalisation as of end-June and end-December. A company that grows can graduate to mid-cap; one that shrinks can fall in.
These are smaller, frequently under-researched businesses — many with market values well below ₹5,000 crore. Far fewer analysts track them than the giants on the Nifty 50, which is precisely where the opportunity, and the danger, lies.
The Risk-Reward Trade-Off
Small-caps can deliver outsized returns when the economy and markets are running hot, because a small company that executes well can multiply in value. But they are also the most volatile and least liquid corner of the market. In downturns they fall harder and faster, and selling a large position without crashing the price can be difficult.
That liquidity squeeze became a live concern during stretches when money poured into small-cap funds faster than managers could sensibly deploy it. Some Indian AMCs took the unusual step of pausing or restricting fresh lump-sum inflows into their small-cap schemes, and SEBI nudged funds to stress-test these portfolios — a clear signal that froth had built up.
For investors, the practical rules are well worn. Small-cap funds suit a long horizon — ideally seven years or more — and an appetite for sharp drawdowns along the way. The SIP route helps, averaging your entry price across the swings rather than betting on a single moment. And they belong as a slice of a portfolio, not its core. Many Indian investors size their small-cap exposure modestly precisely because the same traits that power the upside also make these funds the first to be punished when sentiment turns.
