What are multi-cap mutual funds?

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 diving deeper, 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 hiding 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 investor frequently ask is: "What's the difference between multi-cap and flexi-cap?" Both invest across market caps, but the key difference is structure vs. 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 early 2026, the multi-cap category has 13-14 active funds. The five largest schemes manage over ₹15,000 crore each, with Nippon India Multi Cap Fund leading the pack with approximately ₹47,000+ crore in AUM.

Here is a snapshot of major funds and their performance:

Fund	3-Year CAGR	5-Year CAGR
Nippon India Multi Cap	~23.4%	~23.0%
Mahindra Manulife Multi Cap	~20.1%	~17.9%
Baroda BNP Paribas Multi Cap	~17.5%	~15.1%
Kotak Multicap	Outperformer (2025)	—
SBI Multi Cap	Moderate	—

Note: 2025 was a subdued year for equity markets broadly. Short-term numbers should not be used in isolation. Category average 1-year return in 2025 was ~2.08%.

Multi-cap funds have seen extraordinary retail participation in recent years. Total SIP AUM in multi-cap funds stands around ₹2.05 lakh crore as of August 2025 representing almost a 128% increase from August 2023. The total number of folios has crossed 1.05 crore.

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.

Let's say Priya, a 30-year-old software engineer from Bengaluru, starts a monthly SIP of ₹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 ₹24 lakh grows to roughly ₹1.71 crore, roughly 7x 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 5–7 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 2–3 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 (15%–23% CAGR for top funds over 5 years), 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 7-10 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.
