Small-cap mutual fund
A small-cap mutual fund in India is an open-ended equity scheme that must, under SEBI’s October 2017 scheme categorisation circular, invest a minimum of 65% of its total assets in equity and equity-related instruments of small-cap companies. SEBI defines small-cap companies as all companies ranked 251st and beyond on the full-market-capitalisation list published by AMFI every six months. The small-cap category represents thousands of listed companies, providing an extremely wide investment universe that includes early-stage businesses, niche market leaders, turnaround candidates, and regional franchises.
Small-cap funds offer the highest return potential among domestic equity mutual fund categories, but carry correspondingly high volatility, large drawdowns, significant liquidity risk, and higher sensitivity to governance failures.
Regulatory definition
SEBI October 2017 categorisation circular
SEBI circular SEBI/HO/IMD/DF3/CIR/P/2017/114 dated 6 October 2017 defined small-cap equity funds as:
- Scheme type: Open-ended equity scheme predominantly investing in small-cap stocks.
- Investment universe: Equity and equity-related instruments of small-cap companies (251st rank onwards by full market capitalisation).
- Minimum allocation: At least 65% of total assets in small-cap company stocks.
- Benchmark: Typically NIFTY Smallcap 250 TRI or S&P BSE Smallcap TRI.
AMFI small-cap universe
The AMFI small-cap universe covers all companies ranked 251st and above on the full-market-capitalisation list, which includes thousands of listed companies across NSE and BSE. As of early 2026, companies entering the small-cap universe typically have market capitalisations below approximately ₹5,000 crore to ₹8,000 crore, though this threshold shifts considerably with market conditions. The universe is so large that small-cap fund managers must focus on a curated subset; typical small-cap funds hold 50 to 80 stocks out of a universe of over 4,000 eligible companies.
Asset allocation rules
| Allocation | Requirement |
|---|---|
| Small-cap equity (251st rank onwards) | Minimum 65% of total assets |
| Other equity (large-cap, mid-cap) | Up to 35% of total assets |
| Debt and money-market instruments | Within remaining flexibility |
The 35% residual is used for liquidity management and to maintain exposure to large-cap or mid-cap stocks during periods of small-cap stress or elevated valuations.
Investment characteristics
Small-cap companies in India span an enormous range of business types:
- Micro-cap companies with a single product or single geography, often family-controlled.
- Specialised component manufacturers or ancillaries supplying to large-cap end markets.
- Early-stage consumer brands attempting to scale nationally.
- Niche software, pharmaceutical, or financial services firms.
- Companies in cyclical industries such as textiles, chemicals, engineering, and construction.
The common characteristic is limited institutional research coverage. Many small-cap companies are covered by only one or two brokers, or have no dedicated research coverage, creating the informational asymmetry that generates alpha opportunities for diligent fund managers. However, the same information asymmetry means that adverse developments (management changes, corporate governance failures, sectoral downturns) may not be priced in quickly, exposing investors to sharp unforeseen drawdowns.
Liquidity risk
Liquidity risk is the most distinctive feature of small-cap funds and warrants specific attention. The daily traded volumes in small-cap stocks are often in the range of a few crores of rupees, compared to hundreds of crores for large-cap stocks. When a small-cap fund has grown large (above ₹5,000 crore to ₹10,000 crore in AUM), executing large buy or sell orders can move prices materially.
Several consequences flow from this:
- Impact cost: Buying or selling large tranches of illiquid small-cap stocks at the portfolio level can cause slippage that materially erodes returns.
- Redemption pressure: In a market correction, if many investors simultaneously redeem small-cap fund units, the fund must sell illiquid stocks at depressed prices, compounding losses for remaining unitholders. SEBI’s swing pricing mechanism (introduced in October 2021) is intended to mitigate this, though its application varies by AMC.
- Capacity constraints: Responsible AMC trustees may temporarily pause inflows into small-cap funds when they determine that inflows cannot be deployed at scale without adverse market impact. Several AMCs have invoked such pauses in 2021 to 2024.
Benchmark indices
NIFTY Smallcap 250 TRI: Maintained by NSE Indices Limited, this index covers the 251st to 500th companies from the NIFTY 500 universe by full market capitalisation. It is the standard benchmark for small-cap funds. The NIFTY Smallcap 250 index fund category tracks this index passively.
S&P BSE Smallcap TRI: Maintained by BSE, covers a broader set of small-cap companies listed on BSE. Used by some AMCs as an alternative benchmark.
NIFTY Smallcap 100 TRI: A more concentrated index of 100 small-cap companies, used by some smaller AMC schemes.
Risk profile
Small-cap funds are classified as very high risk:
- Volatility: Annualised standard deviation of 22% to 30%, well above mid-cap (18% to 24%) and large-cap (14% to 18%) funds.
- Drawdowns: Peak-to-trough declines of 50% to 70% during severe bear markets are not uncommon in small-cap fund portfolios. During the 2018 to 2020 small-cap correction, several small-cap funds lost 50% to 60% from their peaks.
- Concentration risk: Given the limited investable universe and the necessity of holding adequate positions, small-cap funds can have outsized exposure to individual stocks or sectors.
- Governance risk: Small-cap companies are more susceptible to promoter-related governance issues, accounting irregularities, and regulatory actions.
- Cyclical risk: Many small-cap companies are concentrated in cyclical industries, making them more sensitive to economic downturns.
Taxation
Small-cap funds are equity-oriented funds and are taxed identically to large-cap funds and mid-cap funds.
Capital gains (Finance Act 2024):
| Holding period | Tax rate |
|---|---|
| Less than 12 months (STCG) | 20% flat |
| 12 months or more (LTCG) | 12.5% on gains above ₹1.25 lakh per year |
Securities Transaction Tax applies on redemptions. The grandfathering rule for LTCG applies to pre-31 January 2018 units. Detailed reporting is required in ITR-2 or ITR-3. See capital gains tax in India for the complete framework.
Expense ratio
TERs for small-cap funds typically range from 0.5% to 2.0% depending on fund size and plan type. Unlike large-cap funds (where passive alternatives at 0.05% to 0.20% TER are directly comparable), small-cap passive index funds are relatively new and their TERs have not yet reached the very low levels seen in large-cap passive funds. The NIFTY Smallcap 250 index fund category typically carries TERs of 0.20% to 0.50%.

Comparison with adjacent categories
Small-cap versus mid-cap fund
Mid-cap funds invest in the 101st to 250th companies by market capitalisation: larger, more liquid, and better researched than small-cap companies. Mid-cap funds carry high risk but typically lower volatility and better liquidity than small-cap funds.
Small-cap versus flexi-cap fund
A flexi-cap fund has no minimum allocation mandate. Fund managers who tactically hold small-cap within a flexi-cap fund may adjust that allocation based on valuations; a dedicated small-cap fund maintains a structural minimum of 65% in small-cap at all times.
Small-cap versus multi-cap fund
A multi-cap fund must hold at least 25% in small-cap stocks as well as 25% each in large-cap and mid-cap, giving it mandatory small-cap exposure with the diversification of the other segments. It is less concentrated in small-cap than a dedicated small-cap fund.
Suitability
Small-cap funds are suitable for:
- Investors with a very high risk appetite and a long investment horizon of 10 years or more.
- Investors who have already built a core portfolio in large-cap or diversified funds and are seeking a satellite allocation with higher return potential.
- Investors who understand and accept the possibility of 50%+ interim drawdowns.
- Investors who will not redeem in a panic during extended bear markets.
Small-cap funds are unsuitable for:
- Investors with less than 7-year horizons.
- Investors who cannot tolerate large capital losses in the short to medium term.
- Investors with liquidity needs from their invested corpus.
- Conservative investors or those close to retirement.
Regulatory oversight
Small-cap mutual funds are regulated by SEBI under the SEBI (Mutual Funds) Regulations, 1996. The mutual fund industry in India operates under the SEBI-AMFI framework. SEBI has periodically issued specific guidance on liquidity risk management, stress testing, and side-pocketing for small-cap funds.
