A Mid Cap Fund invests at least 65% of assets in shares of companies ranked 101st to 250th by market capitalisation — offering higher growth potential than large-caps with more volatility.
SEBI defines mid-cap companies as those ranked 101–250 by full market capitalisation. Mid-cap funds must invest a minimum 65% in these companies. Mid-caps are often established businesses in the growth phase — beyond startup risk but not yet the scale of large-caps. They typically offer better return potential than large-cap funds over long periods but are more volatile and can fall much harder during market corrections.
If large-cap companies are the established players (Reliance, TCS, HDFC Bank), mid-caps are the ambitious challengers — companies like Voltas, Persistent Systems, or SRF Ltd. They're big enough to be serious businesses but still have significant room to grow. A mid-cap fund bets on these companies. The reward: historically better long-term returns than large-cap funds. The risk: sharper downturns in bear markets.
SEBI requires mid-cap funds to invest ≥65% in companies ranked 101–250 by market cap.
AMFI publishes the list of large-cap, mid-cap, and small-cap companies bi-annually.
The remaining 35% can be in any equity/related instruments at the fund manager's discretion.
Mid-cap stocks are less liquid than large-caps — selling large quantities can move prices.
During 2020 COVID crash: Nifty 50 fell ~38%, Nifty Midcap 150 fell ~45% — more pain on the way down. From March 2020 to Dec 2021 recovery: Nifty 50 rose ~115%, Nifty Midcap 150 rose ~175% — bigger bounce. Mid-caps tend to fall harder and rise faster — making them rewarding for patient investors but unsuitable for the risk-averse.
