What are market-cap mutual funds?
Market-cap funds are equity mutual funds grouped by the size of the companies they buy. Size here means market capitalisation: the share price multiplied by the number of shares. A large cap fund owns India's biggest listed businesses; a small cap fund owns much smaller ones that can grow faster but also stumble harder.
Because SEBI fixes the definitions, a large cap fund from one fund house holds broadly the same kind of companies as a large cap fund from another. That makes comparison fair: you judge each scheme against its own category, not against a fund playing a different game.
How the categories differ
| Fund type | Minimum allocation | What to expect |
|---|---|---|
| Large cap | 80% in top 100 companies | Lower swings, steadier compounding |
| Large & mid cap | 35% each in large and mid caps | A blend of stability and growth |
| Mid cap | 65% in companies ranked 101–250 | Higher growth potential, sharper falls |
| Small cap | 65% in companies ranked 251 onwards | Highest volatility, longest horizon |
| Multi cap | 25% each in large, mid and small | Fixed exposure to all three sizes |
The rest of each portfolio can go into other equity, debt or cash, within the limits in the scheme information document.
Who should consider which type
Think of large cap funds as the foundation. A salaried investor starting a first SIP, or a family building a retirement corpus, often begins here because the ride is less bumpy.
Mid and small cap funds suit people who already have that foundation, a long horizon and the temperament to watch their investment fall 30% or more without stopping the SIP. Multi cap and large & mid cap funds are a middle path for those who want some exposure to smaller companies without picking the mix themselves.
Before adding any equity fund, make sure you have an emergency fund and adequate insurance in place, so you are never forced to sell in a falling market.
Things to compare before you choose
- Category fit: match the category to your timeline first, then compare schemes within it.
- Consistency: rolling returns over five and seven years say more than a single strong year.
- Downside: look at how the fund behaved in past corrections compared with its peers.
- Costs: a lower expense ratio leaves more of the return with you over long periods.
- Overlap: two large cap funds may hold many of the same stocks, so more funds do not always mean more diversification.
