Before 2018, two funds could both call themselves “large cap” while holding completely different portfolios. SEBI ended that with a categorisation framework that defines exactly what each fund type may hold. Understanding these categories is the single most useful thing a new investor can learn — because the category decision drives far more of your outcome than the specific fund you pick within it.
Why SEBI Categorised Mutual Funds
Fund houses were running dozens of near-identical schemes with confusing names. An investor could not meaningfully compare two funds, and AMCs could quietly change a fund’s strategy.
SEBI’s framework fixed three things: every fund must belong to exactly one defined category, an AMC may run only one scheme per category, and each category has binding rules on what the fund must hold.
Critically, SEBI also defined company sizes by market capitalisation rank, updated twice yearly by AMFI:
| Classification | SEBI definition |
|---|---|
| Large cap | Companies ranked 1st to 100th by market capitalisation |
| Mid cap | Companies ranked 101st to 250th |
| Small cap | Companies ranked 251st onwards |
Equity Fund Categories
Equity funds invest primarily in shares. SEBI requires at least 65% in equity for a fund to receive equity taxation treatment.
| Category | Mandate | Risk |
|---|---|---|
| Large Cap | At least 80% in the top 100 companies | High |
| Mid Cap | At least 65% in companies ranked 101–250 | Very high |
| Small Cap | At least 65% in companies ranked 251 onwards | Very high |
| Large & Mid Cap | At least 35% each in large cap and mid cap | Very high |
| Flexi Cap | At least 65% equity, free to move across any size | High |
| Multi Cap | At least 25% each in large, mid and small cap | Very high |
| ELSS | At least 80% equity, three-year lock-in, tax deduction eligible | High |
| Focused | Maximum 30 stocks | Very high |
| Value / Contra | Follows a value or contrarian strategy | High |
| Sectoral / Thematic | At least 80% in one sector or theme | Very high |
| Dividend Yield | Predominantly high dividend-yielding stocks | High |
The distinction between Flexi Cap and Multi Cap catches people out. Multi cap must hold at least 25% in each size bucket at all times. Flexi cap has no such floor — the manager can hold 90% large cap if they choose. Flexi cap is the more flexible of the two, despite the similar names.
Debt Fund Categories
Debt funds hold bonds and money-market instruments. SEBI separates them mainly by the duration of what they hold, because duration drives how much a fund moves when interest rates change.
| Category | Typical maturity of holdings | Risk |
|---|---|---|
| Overnight | 1 day | Lowest |
| Liquid | Up to 91 days | Very low |
| Ultra Short Duration | 3–6 months | Very low |
| Low Duration | 6–12 months | Low |
| Short Duration | 1–3 years | Low to moderate |
| Medium Duration | 3–4 years | Moderate |
| Long Duration | Over 7 years | High |
| Corporate Bond | At least 80% in the highest-rated corporate bonds | Low to moderate |
| Credit Risk | At least 65% in bonds below the highest rating | High |
| Gilt | At least 80% in government securities | Moderate — no credit risk, but rate sensitive |
| Banking & PSU | At least 80% in bank and PSU debt | Low to moderate |
Two risks sit inside every debt fund. Interest rate risk — bond prices fall when rates rise, and longer-duration funds fall harder. Credit risk — an issuer may fail to pay. Gilt funds carry no credit risk but plenty of rate risk; credit risk funds are the reverse.
Hybrid Fund Categories
| Category | Equity allocation | Suits |
|---|---|---|
| Conservative Hybrid | 10–25% | Mostly-debt investors wanting a little equity |
| Balanced Hybrid | 40–60% | Middle-ground allocation |
| Aggressive Hybrid | 65–80% | Equity-led with a debt cushion |
| Dynamic Asset Allocation | Varies by market valuation | Investors wanting allocation managed for them |
| Multi Asset Allocation | At least 10% each in three asset classes | Broad diversification including gold |
| Arbitrage | Equity, but market-neutral | Short-term parking with equity taxation |
| Equity Savings | Equity, arbitrage and debt combined | Lower volatility than pure equity |
Other Categories
| Category | What it does |
|---|---|
| Index Funds | Mirrors an index such as the Nifty 50 — no stock picking, low cost |
| ETFs | Index funds that trade on the exchange like a share |
| Fund of Funds | Invests in other mutual funds rather than securities directly |
| Retirement Funds | Solution-oriented, with a lock-in until retirement age |
| Children’s Funds | Solution-oriented, locked until the child reaches a set age |
Which Category Suits You
Match the category to your time horizon first. This matters more than past returns.
| Money needed in | Sensible categories |
|---|---|
| Under 1 year | Liquid, Overnight, Ultra Short Duration |
| 1–3 years | Short Duration, Corporate Bond, Conservative Hybrid |
| 3–5 years | Aggressive Hybrid, Balanced Advantage, Large Cap |
| 5–10 years | Large Cap, Flexi Cap, Index Funds |
| 10+ years | Flexi Cap, Mid Cap, Small Cap, Index Funds |
Putting three-year money into a small cap fund is the most common and most costly category error. Small caps can stay down for years, and needing the money at the wrong moment turns a temporary fall into a permanent loss.
Key Takeaways
- SEBI’s 2018 framework defines every category and its holding rules
- Large cap = top 100 companies, mid cap = 101–250, small cap = 251 onwards
- An AMC may run only one scheme per category
- Flexi cap has no size floors; multi cap must hold 25% in each bucket
- Debt fund categories are defined by duration — longer duration means more rate sensitivity
- Equity taxation applies when a fund holds at least 65% equity
- Choose the category by your time horizon first, then pick a fund within it
Frequently Asked Questions (FAQ)
Q: How many types of mutual funds are there in India?
SEBI’s framework defines 36 categories across five broad groups — equity, debt, hybrid, solution-oriented, and other schemes such as index funds and fund of funds. Each has binding rules on what the fund must hold.
Q: Which type of mutual fund is best for beginners?
For a beginner with a horizon beyond five years, an index fund or a large cap fund is the usual starting point — both are diversified and relatively less volatile than mid or small cap funds. For money needed within a year, a liquid fund is more appropriate than any equity fund.
Q: What is the difference between flexi cap and multi cap funds?
Multi cap funds must hold at least 25% each in large, mid and small cap stocks at all times. Flexi cap funds have no such requirement — the manager can allocate freely across sizes. Flexi cap is more flexible despite the similar name.
Q: Which mutual fund category has the highest returns?
Small cap funds have historically delivered the highest returns over long periods, but with the deepest falls along the way. Higher long-term return and higher short-term volatility are two sides of the same characteristic — the category is only suitable if you can leave the money untouched for seven to ten years.
Q: What is the safest mutual fund category?
Overnight and liquid funds carry the lowest risk because they hold very short-maturity instruments with minimal interest rate and credit exposure. They are designed for parking money, not for growing it.
Q: Can I invest in more than one mutual fund category?
Yes, and most investors should. A common structure is a liquid fund for emergency money, a debt or hybrid fund for goals three to five years out, and equity funds for long-term goals. Holding many funds within the same category, though, adds overlap rather than diversification.
Q: How often does SEBI update the large, mid and small cap lists?
AMFI publishes the classification twice a year, based on average market capitalisation over the previous six months. Funds are given a window to rebalance their portfolios when a company moves between buckets.
