SEBI's Mutual Fund Categories Explained: What a Scheme's Label Tells You

Before 2017, it was hard to compare mutual fund schemes in India. Two funds with similar names could hold very different portfolios, and fund houses often ran several near-identical schemes. On 6 October 2017, SEBI issued a circular on the categorisation and rationalisation of mutual fund schemes that changed this. It defined standard categories, told fund houses what each category must broadly invest in, and limited them to one scheme per category in most cases. Understanding those categories is one of the quickest ways to understand what you actually own.

The broad families

SEBI's framework groups schemes into broad families. Each family contains several categories with defined investment mandates:

• Equity schemes, which invest mainly in shares and are grouped by company size, investment style, or theme.
• Debt schemes, which invest in bonds and money market instruments and are grouped mainly by the duration and credit quality of what they hold.
• Hybrid schemes, which mix equity and debt in different proportions.
• Solution-oriented schemes, built around goals such as retirement or children's needs, usually with a lock-in.
• Other schemes, which include index funds, exchange-traded funds, and funds of funds.

How large, mid, and small caps are defined

One of the most useful parts of the framework is a common definition of company size. Under SEBI's definitions, large-cap companies are the 1st to 100th companies by full market capitalisation, mid-cap companies are the 101st to 250th, and small-cap companies are the 251st onward. AMFI publishes the ranked list periodically so that every fund house uses the same classification.

This matters because a large-cap fund must keep most of its equity money in those top 100 companies, while a small-cap fund must keep most of its money in smaller ones. The labels therefore tell you a great deal about the type of risk you are taking. Smaller companies have historically been more volatile, with larger rises and deeper falls, and can be harder to trade in large quantities.

Equity categories by style and focus

Beyond size, equity categories describe how a fund invests. Some must spread money across company sizes, others concentrate on a limited number of stocks, follow a value or contrarian style, focus on dividend-paying companies, or stick to a single sector or theme such as banking or infrastructure. Equity-linked savings schemes are also an equity category, carrying a lock-in period.

Sectoral and thematic funds deserve special care. Because they concentrate on one part of the economy, their returns can diverge sharply from the broad market for long stretches, in either direction. They behave very differently from a diversified fund, even though both are labelled equity.

Debt categories: duration and credit

Debt fund categories are defined mainly by two things. The first is how sensitive the portfolio is to interest rate changes, usually described through duration or the maturity of the instruments held. Overnight and liquid funds hold very short-term instruments, while long-duration and gilt funds can hold bonds that mature many years out. Longer duration means bond prices move more when interest rates change.

The second is credit quality. Some categories, such as corporate bond funds, must hold mostly highly rated bonds, while credit risk funds deliberately hold lower-rated paper in exchange for higher yields, and with it, a higher chance that an issuer fails to pay. Two debt funds with similar recent returns can carry very different risks depending on which of these dimensions they lean on.

Hybrid categories: the mix is the point

Hybrid categories are defined by how much they hold in equity versus debt, and whether that mix is fixed or managed dynamically. Some are mostly debt with a small equity portion, some are mostly equity with a debt cushion, and some — often called balanced advantage or dynamic asset allocation funds — shift between the two based on the fund house's model. Arbitrage funds, also hybrid, use simultaneous cash and derivatives positions to earn a spread with relatively low volatility, but they are not the same as a bank deposit.

The riskometer

Every scheme displays a riskometer, a SEBI-mandated label that places it on a scale from low to very high risk based on what it holds. The riskometer is updated as the portfolio changes, and it is a quick sanity check: if you thought you were buying something conservative and the riskometer says very high, the category and portfolio deserve a closer look.

Using categories to build a portfolio

Categories help you avoid accidental duplication. Three funds from three different fund houses, all in the large-cap category, will often hold many of the same companies. Owning all three adds paperwork but little diversification. Looking at categories first, and individual schemes second, is a simple way to check whether a portfolio has the spread you intended across company size, asset class, and interest-rate sensitivity.

• Start with asset allocation: how much in equity, how much in debt, and why, based on when you need the money.
• Then decide which categories fit each part. A long-term equity portion might use diversified categories; money needed soon belongs in short-duration, high-quality debt categories.
• Check overlap before adding a scheme from a category you already hold.
• Read the scheme information document for the exact mandate, since categories define broad limits rather than identical portfolios.

A worked example makes the point. Suppose you hold ₹2,00,000 split across a large-cap fund, a flexi-cap fund, and a large-and-mid-cap fund. On paper that is three schemes. In practice, all three may hold many of the same large companies, so your effective exposure to the biggest stocks could be much higher than you think, while your exposure to debt is zero. Grouping holdings by category first makes this visible in a minute, before any detailed portfolio comparison.

What categories cannot tell you

A category describes what a scheme may own, not how well it is managed. Within the same category, schemes differ in expense ratios, stock selection, portfolio concentration, and how closely they hug or deviate from their benchmark. Past returns within a category also vary widely and are not a reliable guide to future performance. The category is the starting point for comparison, not the conclusion.

SEBI updates its rules from time to time, so for the current definitions and limits, the primary source is SEBI's circulars and each scheme's own documents. AMFI's investor education material is a good plain-language companion.
