Large Cap, Mid Cap, Small Cap: India Guide

What do large cap, mid cap and small cap mean in India?

In India, large cap, mid cap and small cap are official categories based on a company’s market capitalisation rank, as defined by the market regulator SEBI. The top 100 listed companies by market capitalisation are large cap, the next 150 are mid cap, and all remaining listed companies are small cap. This ranking is updated periodically, so a company can move between categories over time.

Market capitalisation is simply the share price multiplied by the number of shares outstanding. It is a measure of the total market value of a company’s equity. Because prices change daily, the exact ranking can shift, but SEBI’s definitions give investors and fund managers a common language.

How SEBI classifies companies by market capitalisation

SEBI’s circular from October 2017 set out this classification for mutual funds. The rules are based on the average market capitalisation of companies over the previous six months. The top 100 companies are large cap, the 101st to 250th companies are mid cap, and companies ranked 251 and below are small cap.

This is a relative ranking, not a fixed rupee threshold. A company that was mid cap last year could become large cap if its market value rises, or small cap if it falls. The Association of Mutual Funds in India (AMFI) publishes the updated list twice a year, and mutual funds must rebalance their portfolios within a month when a stock changes category.

Why the ranking matters for investors

The classification helps investors understand the basic risk and return profile of a stock or fund. It also determines which mutual fund category a scheme belongs to, which affects what it must invest in and how it can be described. For example, a large cap fund must invest at least 80% of its assets in large cap stocks, while a mid cap fund must invest at least 65% in mid cap stocks.

How risk and returns tend to differ

Large cap companies are typically well-established, with stable revenues and strong liquidity. Their shares tend to be less volatile than smaller companies, but they may grow more slowly. Mid cap companies are often in a growth phase, with more room to expand but also more sensitivity to economic cycles. Small cap companies can offer the highest growth potential, but they also carry the highest risk of sharp price swings and lower trading volumes.

Historically, small caps and mid caps have shown higher volatility than large caps, but they have also delivered periods of strong outperformance. However, returns are not guaranteed, and the gap between the best and worst performers within each category can be wide. Diversification across categories can help balance risk and return.

Liquidity and volatility

Liquidity refers to how easily a stock can be bought or sold without affecting its price. Large cap stocks usually trade in high volumes, so they are more liquid. Small cap stocks may have lower trading volumes, which can make it harder to buy or sell a large quantity without moving the price. This is an important consideration for investors who may need to exit quickly.

How mutual funds use these categories

SEBI has defined specific categories for equity mutual funds based on market capitalisation. A large cap fund must invest at least 80% of its assets in large cap stocks. A mid cap fund must invest at least 65% in mid cap stocks, and a small cap fund must invest at least 65% in small cap stocks. There are also large and mid cap funds (at least 35% in large caps and 35% in mid caps), multi cap funds (at least 75% in equities, with at least 25% each in large, mid and small caps) and flexi cap funds (at least 65% in equities, in companies of any size).

These rules make it easier for investors to know what they are buying. A large cap fund is not allowed to suddenly shift most of its money into small caps, for example. However, fund managers still have some flexibility within the category limits.

Common mistakes and risks to watch

• Chasing past performance: A fund that performed well last year may not repeat it. Small cap funds can be especially volatile.
• Ignoring liquidity: Small cap stocks can be hard to sell in a downturn, which may affect fund redemptions.
• Over-diversification: Holding too many funds across categories can dilute returns and make your portfolio hard to track.
• Misunderstanding category labels: A mid cap fund can hold some large cap stocks, and a small cap fund can hold mid caps. Always check the portfolio.
• Forgetting costs: Expense ratios and exit loads can eat into returns, especially in actively managed funds.

It is also important to remember that market capitalisation categories are not a measure of quality. A large cap company can be poorly managed, and a small cap company can be well run. The category only describes size, not investment merit.

Frequently asked questions

What is a large cap stock?

A large cap stock is one of the top 100 listed companies in India by market capitalisation, according to SEBI’s ranking. These are typically well-established companies with stable businesses.

How often do SEBI’s market cap categories change?

SEBI’s categories are based on average market capitalisation over the previous six months and are updated periodically, usually twice a year. Companies can move between categories as their market value changes.

Are small cap stocks riskier than large cap stocks?

Yes, small cap stocks generally carry higher risk due to lower liquidity and greater price volatility. They can also offer higher growth potential, but with more uncertainty.

Can a mutual fund invest across large, mid and small caps?

Yes, multi cap funds must invest at least 75% of their assets in equities, with at least 25% each in large, mid and small cap stocks. Flexi cap funds can move freely between sizes, and large and mid cap funds focus on those two categories.

Key takeaways

• SEBI classifies listed companies into large cap (top 100), mid cap (next 150) and small cap (rest) by market capitalisation rank.
• Large caps tend to be more stable and liquid; mid and small caps can offer higher growth but with more risk.
• Mutual fund categories have minimum investment requirements in each segment, so investors should check the fund’s mandate.
• Diversification and a long-term view can help manage the risks of investing in different market cap segments.
