What is a flexi cap fund?
A flexi cap fund is a type of equity fund. Equity means company shares. A mutual fund is a pool of money from many investors, run by professional managers. SEBI, India's fund regulator, sets these rules. A flexi cap fund must always keep at least 65% of its money in shares. SEBI's official description is "an open ended dynamic equity scheme investing across large cap, mid cap, small cap stocks." Open ended means you can buy in or sell out on any working day.
Company size in India is measured by market capitalisation: the total value of a company's listed shares, found by multiplying the share price by the number of shares. AMFI, the industry body, ranks every listed company by this measure twice a year. The 100 biggest are large cap. The next 150, ranked 101 to 250, are mid cap. Everything ranked 251 and below is small cap.
A flexi cap fund can hold any mix of large, mid and small cap shares. There is no minimum for any single size band, only the 65% floor overall. A category is SEBI's label for what a fund may hold, and SEBI created this one in a circular dated 6 November 2020. Today the rule sits in SEBI's framework in force since 26 February 2026.
Money not in shares can sit in money market instruments (short-term lending), InvITs (trusts that own infrastructure such as roads or power lines) or gold and silver instruments, each capped separately. Because nothing forces the size mix to stay put, a flexi cap manager can move from small caps into large caps, or back again, far more freely than a multi cap manager, who must keep at least 25% in each size band.
At the latest count, 43 flexi cap funds were listed in the regular plan (bought through a distributor) with the growth option (gains stay invested, not paid out), holding ₹6,05,936 Cr between them.
