Mid-cap mutual fund
A mid-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 mid-cap companies. SEBI defines mid-cap companies as the 101st to 250th companies listed on a recognised stock exchange, ranked by full market capitalisation, as enumerated in the AMFI list published every six months. Mid-cap funds occupy the risk-return space between large-cap funds and small-cap funds, offering higher long-term return potential than large-cap funds at the cost of higher volatility and larger drawdowns.
Regulatory definition
SEBI October 2017 categorisation circular
SEBI’s circular no. SEBI/HO/IMD/DF3/CIR/P/2017/114 dated 6 October 2017 defined mid-cap equity funds as follows:
- Scheme type: Open-ended equity scheme predominantly investing in mid-cap stocks.
- Investment universe: Equity and equity-related instruments of mid-cap companies.
- Minimum allocation: At least 65% of total assets in mid-cap company stocks.
- Benchmark: Typically NIFTY Midcap 150 TRI or S&P BSE Midcap TRI.
The 35% residual may be deployed in large-cap stocks, small-cap stocks, debt instruments, or cash, at the fund manager’s discretion.
AMFI mid-cap universe
AMFI publishes the list of top 500 companies by full market capitalisation every six months (in January and July). Companies ranked 101st to 250th on this list are classified as mid-cap. As of early 2026, the mid-cap range corresponds roughly to companies with market capitalisations between approximately ₹5,000 crore and ₹35,000 crore, though these thresholds shift with market conditions. Fund managers must rebalance their portfolios within 30 days of each AMFI list update.
Asset allocation rules
| Allocation | Requirement |
|---|---|
| Mid-cap equity (101st–250th companies) | Minimum 65% of total assets |
| Other equity (large-cap, small-cap) | Up to 35% of total assets |
| Debt and money-market instruments | Within the remaining flexibility |
The 35% residual sleeve is used differently by different fund managers. Some maintain a structural large-cap sleeve of 15% to 20% to reduce volatility and aid liquidity; others use the flexibility to hold small-cap positions for higher upside.
Investment characteristics
Mid-cap companies in India occupy the growth phase of their corporate lifecycle. They are typically:
- Large enough to have a proven business model, a recognisable brand or product, and a multi-year operating history.
- Small enough to have significant headroom for market share gains, capacity expansion, or geographical diversification.
- Less well-covered by institutional research than large-cap companies, creating information asymmetry that skilled fund managers may exploit.
- More sensitive to domestic economic cycles, credit availability, and interest rates than multi-national large-cap companies.
Sectors commonly over-represented in mid-cap funds relative to the broad market include specialty chemicals, consumer discretionary, industrial capital goods, mid-sized financial services companies, healthcare and diagnostics, real estate, and regional infrastructure plays.
Benchmark indices
NIFTY Midcap 150 TRI: This is the standard benchmark for mid-cap funds. It is maintained by NSE Indices Limited and covers the 101st to 250th companies from the NIFTY 500 universe by full market capitalisation. The NIFTY Midcap 150 index fund category tracks this index passively.
S&P BSE Midcap TRI: Used by some AMCs as an alternative. It covers approximately 150 mid-cap companies listed on BSE.
Risk profile
Mid-cap funds carry high to very high risk. Key risk characteristics:
- Volatility: Annualised standard deviation of mid-cap fund returns is typically 18% to 24%, materially higher than large-cap funds (14% to 18%).
- Drawdowns: During market corrections, mid-cap funds typically fall 30% to 50% from peak, compared to 20% to 35% for large-cap funds.
- Liquidity risk: Mid-cap stocks have lower average daily trading volumes than large-cap stocks, which means large redemptions in mid-cap funds can be disruptive to prices if the fund is large relative to the stock’s liquidity.
- Recovery time: Mid-cap funds typically take longer to recover from drawdowns than large-cap funds, though they also tend to deliver sharper rallies in early-cycle recoveries.
- Information risk: Thinner analyst coverage increases the risk of portfolio companies having undisclosed governance or financial issues.
Performance characteristics
Historically, over 7-year and 10-year periods, mid-cap funds in India have generated higher returns than large-cap funds, reflecting the higher risk premium of mid-cap investing. However, this outperformance is not consistent across all periods: during prolonged bear markets or credit crunches (such as 2018 to 2020), mid-cap funds underperform large-cap funds substantially. The NIFTY Midcap 150 index fell approximately 40% between January 2018 and March 2020 even as the NIFTY 50 fell only 25% to 30% over the same period.
The wide dispersion of returns among individual mid-cap fund schemes is significantly higher than in large-cap funds, reflecting the larger active management universe and the higher skill premium available to fund managers who can identify mispriced mid-cap stocks.
Taxation
Mid-cap funds are equity-oriented funds (more than 65% in domestic listed equities) and are taxed accordingly.
Capital gains (as per 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 units acquired before 31 January 2018. Refer to capital gains tax in India for the full framework. Investors must report gains in ITR-2 or ITR-3.
Dividend income is taxable at the investor’s applicable slab rate.
Expense ratio
Mid-cap funds typically carry TERs between 0.6% and 2.0% depending on the scheme size and plan type (direct or regular). The same SEBI TER slabs applicable to all equity funds apply. Given the active management value available in the mid-cap space, the TER differential between active mid-cap funds and passive mid-cap index funds (typically 0.15% to 0.40%) is considered more justifiable than in the large-cap space.
Exemplar schemes

- HDFC Mid-Cap Opportunities Fund (HDFC Mutual Fund)
- Kotak Emerging Equity Fund (Kotak Mahindra Mutual Fund)
- Nippon India Growth Fund (Nippon India Mutual Fund)
- SBI Magnum Midcap Fund (SBI Mutual Fund)
- Axis Midcap Fund (Axis Mutual Fund)

Comparison with adjacent categories
Mid-cap versus large-cap fund
Large-cap funds restrict at least 80% to the top 100 companies, giving them lower volatility and higher liquidity but constraining the active management opportunity set. Mid-cap funds access a broader universe of 150 companies with higher growth potential and more active management scope.
Mid-cap versus small-cap fund
Small-cap funds invest at least 65% in companies ranked 251st and below, which are smaller and less liquid than mid-cap companies. Small-cap funds carry higher volatility, larger drawdowns, and more liquidity risk, but may offer higher long-term returns in favourable market conditions.
Mid-cap versus large-and-midcap fund
A large-and-midcap fund must hold at least 35% each in large-cap and mid-cap stocks. This provides a blended exposure with lower volatility than a pure mid-cap fund.
Mid-cap versus flexi-cap fund
A flexi-cap fund has no minimum allocation to any market-cap segment. In practice, many flexi-cap funds maintain high large-cap allocations and resemble large-cap funds more than mid-cap funds.
Mid-cap versus multi-cap fund
A multi-cap fund must hold at least 25% each in large-cap, mid-cap, and small-cap stocks. It provides structured three-segment exposure with a mandatory minimum mid-cap allocation.
Suitability
Mid-cap funds are suitable for:
- Investors with a high risk appetite and a long investment horizon of 7 years or more.
- Investors who are comfortable with significant interim volatility and drawdowns of 30% to 50%.
- Investors seeking higher long-term return potential than large-cap funds and willing to accept higher risk.
- Investors using mid-cap funds as a satellite allocation alongside a large-cap or flexi-cap core holding.
Mid-cap funds are less suitable for:
- Investors with short investment horizons (below 5 years).
- Investors who cannot tolerate large interim losses without panic-redeeming.
- Investors approaching retirement who require capital preservation.
Regulatory oversight
Mid-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. Investor grievances may be filed on SEBI’s SCORES platform.
