2.4.1 Equity Fund Categories
Equity fund categories range from large cap to small cap, and from sectoral bets to broad multi cap strategies. Each category follows regulator-defined rules about where it can invest, making comparisons within a category more meaningful.
The size-based categories
Large cap, mid cap and small cap funds are defined by regulation according to which size segment of the market they must primarily invest in. Multi cap and flexi cap funds are given more freedom to move across these segments, with flexi cap funds having the widest discretion over how they allocate between large, mid and small companies.
SEBI's 2017 categorisation framework classifies equity mutual funds into strictly defined buckets. Large-cap funds must invest at least 80% in the top 100 companies by market cap. Mid-cap funds must invest at least 65% in companies ranked 101-250. Small-cap funds must invest at least 65% in companies ranked 251 and below. Multi-cap funds must invest at least 25% each in large, mid and small caps. Flexi-cap funds can invest across market caps without minimum thresholds, giving the fund manager full discretion.
These are not marketing labels. They are regulatory mandates with compliance requirements. A fund categorised as large-cap cannot hold 50% in small-caps even if the manager believes small-caps will outperform. This constraint protects investors by ensuring the fund they bought does what the label promises, but it also limits the manager's flexibility. Understanding the category's rules tells you what the fund can and cannot do, which is more reliable information than the fund's recent returns.
The style-based categories
Value funds look for companies trading cheaply relative to fundamentals. Contra funds deliberately go against prevailing market sentiment. Dividend yield funds focus on companies with a strong history of dividend payouts. Focused funds concentrate their portfolio in a smaller number of high-conviction holdings rather than spreading across many.
Beyond market-cap-based categories, SEBI defines style-based equity categories. Value funds invest with a value investing approach (low P/E, low P/B stocks). Contra funds take contrarian positions against prevailing market sentiment. Focused funds hold a concentrated portfolio of at most 30 stocks. Dividend yield funds invest in high-dividend-paying stocks. Sectoral and thematic funds invest in specific industries or themes. ELSS funds offer Section 80C tax deductions with a 3-year lock-in.
Each style category carries distinct risk characteristics beyond what the market-cap exposure suggests. A focused fund with 25 stocks has significantly higher concentration risk than a diversified large-cap fund with 50-70 stocks, even if both hold primarily large-cap names. A value fund may underperform in momentum-driven markets for extended periods before its approach pays off. The style label is not a performance guarantee; it is a risk description that the investor should understand before committing.
Why the category label matters
A fund's category determines the rules it must follow and the benchmark it should reasonably be judged against. Comparing a small cap fund's returns directly to a large cap fund's returns, without accounting for the very different risk each category carries, is one of the more common mistakes investors make when evaluating fund performance.

For most investors building a core equity allocation, a flexi-cap or multi-cap fund serves as a sensible starting point because it provides broad market exposure without forcing a specific size or style bet. Satellite allocations to specific categories (mid-cap, small-cap, value) can be added based on conviction, time horizon and risk tolerance. The category decision is the most consequential choice in equity fund selection; the fund choice within a category is secondary. Getting the category right and the fund slightly wrong produces a better outcome than getting the fund right within the wrong category.
