Before learning about the difference between small-cap, mid-cap, and large-cap, let's understand market capitalisation, or market cap, as it forms the basis of how these categories are defined. Simply put, the market cap is the total value of a company's outstanding shares in the stock market.
To calculate this, you multiply the number of outstanding shares by the current stock price. For example, if a company has 10 million shares priced at ₹100 each, its market cap would be ₹1,000 million or ₹100 crores. Companies with higher market caps are usually larger, more stable, and well-established, while those with lower market caps might be growth-focused but come with increased risk.
Large-cap stocks represent well-established and financially stable companies. In India, SEBI defines large-cap companies as those ranking from the 1st to 100th position in terms of total market capitalisation. These companies are typically household names with a strong market presence.
Key characteristics of large-cap stocks:
Mid-cap stocks sit between large-cap and small-cap stocks. In India, mid-cap companies are ranked from 101st to 250th in market capitalisation. They are often considered growth stocks because they have already proven themselves but still have significant potential for expansion.
Key characteristics of mid-cap stocks:
Small-cap stocks refer to companies with lower market capitalisation, typically ranked 251st onwards, according to SEBI. These companies are often in their early stages of growth and can offer high returns, but they come with higher risk and volatility.
Key characteristics of small-cap stocks:
The difference between these categories lies in the size and stability of the companies, which also affects risk and potential returns. Here's a quick comparison:
| Aspect | Large-cap | Mid-cap | Small-cap |
| Company type | Well-established, stable | Established, growth potential | Emerging, high growth potential |
| Market capitalisation | ₹20,000 crore or more | ₹5,000 crore to ₹20,000 crore | Less than ₹5,000 crore |
| Volatility | Generally low | Moderate | High |
| Risk | Lowest | Medium | Highest |
| Returns | Stable and steady | Potential for higher returns | Potential for highest returns |
| Liquidity | High (easier to buy/sell) | Lower (maybe less tradable) | Least (may be difficult to buy/sell) |
When engaging in share market trading, it's important to understand these categories to make informed investment decisions. The choice between large-cap, mid-cap, and small-cap stocks depends on your risk appetite.
For conservative investors, large-cap stocks are ideal, as they provide stability and lower risk. Mid-cap stocks appeal to moderate investors who seek a balance of risk and growth potential. On the other hand, small-cap stocks are typically preferred by aggressive investors willing to take higher risks for the chance of substantial returns.
