Mid-Cap Funds
Mid-cap funds are equity mutual funds that must invest at least 65% of their assets in mid-sized companies, ranked 101st to 250th by full market capitalisation, seeking higher growth with higher volatility.
What Is a Mid-Cap Fund?
A mid-cap fund is an equity mutual fund that invests mainly in medium-sized listed companies. SEBI requires a mid-cap fund to invest at least 65% of its total assets in equity and equity-related instruments of mid-cap companies.
Mid-sized companies are often past the early start-up stage but still growing. Some may become tomorrow's large caps; others may stall. That mix of opportunity and uncertainty is what makes mid-cap funds more volatile than large-cap funds.
How Does a Mid-Cap Fund Work?
- Universe: The fund manager selects mainly from companies ranked 101st to 250th on AMFI's list.
- Minimum allocation: At least 65% of assets must be in these mid caps.
- Flexible residual: Up to 35% can go into large caps, small caps, money market instruments or other assets permitted by SEBI. Many managers use part of this for large caps to add stability.
- Half-yearly list changes: When AMFI updates the list, a stock that grows into the top 100 becomes a large cap; one that shrinks below 250th becomes a small cap. Funds rebalance within one month where required.
- Benchmark: Performance is measured against a mid-cap index.
Practical Example
Illustrative: Kunal invests ₹1,00,000 in a mid-cap fund. Over three years, the hypothetical returns are:
- Year 1: −25% → ₹1,00,000 × 0.75 = ₹75,000
- Year 2: +40% → ₹75,000 × 1.40 = ₹1,05,000
- Year 3: +20% → ₹1,05,000 × 1.20 = ₹1,26,000
Total gain = ₹26,000. The annualised return (CAGR) = (1,26,000 ÷ 1,00,000)^(1/3) − 1 ≈ 8.0% a year.
Notice two lessons:
- After a 25% fall, the fund needed a gain of 33.3% (₹25,000 ÷ ₹75,000) just to get back to ₹1,00,000.
- Had Kunal redeemed at the end of year 1 out of fear, he would have locked in a ₹25,000 loss.
These figures are illustrative, not actual fund data.
Why Is It Important?
- Growth potential: Mid-sized companies can grow earnings faster than mature large companies, which may lead to higher long-term returns, though this is not guaranteed.
- Higher volatility: Mid caps can fall more sharply than large caps during market corrections.
- Liquidity: Mid-cap shares trade less than large caps, so big buy or sell orders can move prices, especially in stressed markets.
- Time horizon: Mid-cap funds generally need a longer holding period, often seven years or more, to ride out cycles.

Tax treatment

How Does It Apply to Mutual Fund Investors?
- Allocation size: Many investors keep mid caps as a part, not the whole, of their equity allocation, sized to their risk appetite.
- SIP suitability: SIPs can help in this volatile category by buying more units in falls. See Rupee Cost Averaging.
- Evaluation: Compare rolling returns and downside behaviour, not just trailing returns.
- Documents: Check the SID for how much the fund may hold outside mid caps.
Common Mistakes and Misconceptions
- "Mid caps always beat large caps over the long term." They have done so in some periods but not others. Outperformance is not assured.
- "I can invest in mid-cap funds for a two-year goal." A downturn could leave you with a loss just when you need the money.
- "Mid-cap funds hold only mid caps." Only 65% must be in mid caps; the rest can be large caps, small caps or cash.
- "Last year's top fund will repeat." Rankings in this category change frequently.
Important Terms to Know
- Volatility: How much prices swing over time.
- Large-Cap Funds: Funds investing mainly in the top 100 companies.
- Small-Cap Funds: Funds investing mainly in companies ranked 251st onwards.
- Liquidity Risk: Difficulty in selling at a fair price.
- CAGR: The annualised growth rate over a period.
- Risk Appetite: How much risk you are willing to take.
Key Takeaways
- Mid-cap funds invest at least 65% in companies ranked 101st to 250th by market capitalisation.
- They offer higher growth potential than large caps with noticeably higher volatility.
- A long horizon and patience through downturns are essential.
- Use them as part of a diversified equity portfolio, sized to your risk appetite.

Frequently Asked Questions
How risky are mid-cap funds?
Mid-cap funds are generally more volatile than large-cap funds and less volatile than small-cap funds. They can fall sharply in market corrections and take time to recover. They are usually labelled "Very High" risk and suit investors with long horizons and tolerance for large swings.
What is a mid-cap company?
In Indian mutual fund rules, a mid-cap company is ranked between 101st and 250th by full market capitalisation on the list AMFI publishes every six months. These companies are larger than small caps but smaller than the top 100.
How long should I stay invested in a mid-cap fund?
There is no fixed rule, but because of their volatility, mid-cap funds generally suit goals at least seven years away. A longer horizon gives more time to recover from downturns, although it does not remove risk.
Can a mid-cap fund invest in large caps?
Yes. Only 65% must be in mid-cap stocks. The remaining up to 35% can be invested in large caps, small caps, money market instruments and other permitted assets, depending on the scheme's stated asset allocation.
Is a SIP better than a lump sum for mid-cap funds?
A SIP spreads investments over time and reduces the risk of investing everything at a market peak, which can be helpful in a volatile category. A lump sum may do better if markets rise steadily after investing. Neither approach guarantees better results.
