What are multi-cap mutual funds?

Last Reviewed and Updated: 17 Aug 2026

A multi-cap mutual fund is an open-ended equity scheme that invests across all three market capitalisation segments simultaneously: large-cap, mid-cap, and small-cap companies. SEBI mandates that at least 75% of assets are invested in equities, with a minimum of 25% allocated to each segment.

This mandatory 25-25-25 split is what sets multi-cap funds apart from their cousin, the flexi-cap fund, which has no such floor requirement per segment.

Before going further, it’s important to understand how the regulator classifies companies. SEBI defines large-cap, mid-cap, and small-cap based purely on market capitalisation rank on Indian stock exchanges:

Segment	SEBI rank	Min. allocation
Large-cap	1st to 100th by market cap	25%
Mid-cap	101st to 250th by market cap	25%
Small-cap	251st and beyond	25%

This means a fund can’t simply call itself ‘multi-cap’ while secretly parking 80% of the portfolio in Reliance and HDFC Bank. The allocation floor ensures genuine diversification.

Multi-cap funds existed long before 2020, but they operated very differently. Before SEBI’s 2020 circular, the only condition was that 65% of assets be in equities with no segment-level floor. In practice, most ‘multi-cap’ funds were quietly behaving like large-cap funds, sometimes with more than 80% in large-cap stocks.

In September 2020, SEBI put an end to this. The new rule increased the minimum equity allocation from 65% to 75% and mandated 25% each in large-cap, mid-cap, and small-cap. This was a watershed moment for genuine diversification in the category.

One question investors frequently ask is: “What’s the difference between multi-cap and flexi-cap?” Both invest across market caps, but the key difference is structure versus freedom.

Feature	Multi-Cap	Flexi-Cap
Min. equity allocation	75%	65%
Large-cap floor	25% mandatory	No floor
Mid-cap floor	25% mandatory	No floor
Small-cap floor	25% mandatory	None
Fund manager flexibility	Moderate	High

In a flexi-cap fund, the manager can shift heavily towards large-caps during a downturn and aggressively move into small-caps during a bull run. A multi-cap manager is constrained by the 25% floors, which is both a limitation and a safety feature.

As of mid-2026, the multi-cap category has grown to 36 active funds. Nippon India Multi Cap Fund remains the largest, with AUM of approximately Rs 54,500 crore, followed by Kotak Multicap Fund and SBI Multicap Fund, each above Rs 20,000 crore.

Here is a snapshot of major funds and their performance:

Fund	3-Year CAGR	5-Year CAGR
Nippon India Multi Cap	~16.1%	~19.6%
Kotak Multicap	~19.6%	N/A (newer fund)
Category average	~17.0%	~15.3%
SBI Multicap	N/A (newer fund)	N/A (newer fund)

Note: figures above are approximate CAGRs as of August 2026 and vary by data source. 2025 was a subdued year for Indian equity markets broadly, and March 2026 saw a sharp correction, so recent 1-year figures are notably lower than 3 and 5-year averages.

Multi-cap funds have seen extraordinary retail participation in recent years. Total AUM across the multi-cap category stands around Rs 2.43 lakh crore as of August 2026, up from roughly Rs 2.05 lakh crore a year earlier, even after the market correction earlier in 2026 pulled valuations down.

This is a testament to the “set-and-forget” appeal of multi-cap funds. Investors who don’t want to manage separate large-cap, mid-cap, and small-cap fund allocations can get a one-fund-fits-all solution.

Say Priya, a 30-year-old software engineer from Bengaluru, starts a monthly SIP of Rs 10,000 in a multi-cap fund. Here’s how her corpus could grow over 10 and 20 years:

Scenario (₹10,000/month SIP)	10 Years	20 Years
Conservative - 12% CAGR	₹23.2 lakh	₹98.9 lakh
Moderate - 16% CAGR	₹30.1 lakh	₹1.71 crore
Fixed Deposit - 7% p.a.	₹17.4 lakh	₹52.6 lakh

At a moderate 16% CAGR over 20 years, Priya’s total invested amount of Rs 24 lakh grows to roughly Rs 1.71 crore, roughly 7 times her invested capital. The power of compounding across all three cap segments is what makes this category compelling.

The mandatory equal allocation rule has sparked significant debate in the industry. The 25% mandate means 50% of the portfolio is in mid-cap and small-cap stocks, which tend to be more volatile during bearish phases. Despite this, fund managers cannot reallocate towards relatively stable large-cap stocks during downturns, which can amplify drawdowns.

Critics argue this rigidity removes the tactical flexibility that makes active fund management valuable. Supporters counter that it delivers on the promise of genuine diversification. Both views have merit, and the right answer depends on your investment horizon and risk appetite.

Multi-cap funds are best suited for:

• Investors who want full equity market exposure in a single scheme

• Those with a time horizon of at least 5 to 7 years (to ride out small-cap volatility)

• Moderate to high risk tolerance investors

• Those earlier in their investment journey who prefer simplicity

Less ideal for:

• Conservative investors who need capital protection

• Retirees or those within 2 to 3 years of a major financial goal

• Investors who want active control over their cap allocation split

Multi-cap mutual funds offer a uniquely structured solution to the classic diversification challenge. The SEBI-mandated 25-25-25 structure ensures genuine diversification, not just the label. Long-term return potential is strong, the tax treatment is favourable, and the SIP route makes them accessible to virtually any investor.

The caveat is real: mandatory small-cap and mid-cap exposure means sharper drawdowns during corrections, as 2025’s muted returns demonstrated. But for investors with a 7 to 10 year horizon and the discipline to stay invested through volatility, multi-cap funds are one of the most efficient vehicles the Indian market has to offer.
