 1. What is Market Capitalisation?

Market Capitalisation represents the total value of a company as determined by the stock market. It reflects what the public perceives a company to be worth. This figure provides insight into a company's size, performance expectations, and investment characteristics.


 2. How Is Market Capitalisation Calculated?

The formula is straightforward:

Market Cap = Current Share Price × Total Number of Outstanding Shares

For example, if AGSSL Corp. has 100 crore shares trading at ₹200 each, the market cap is:

₹200 × 100 crore = ₹20,000 crore

This number becomes the benchmark for classification.


 3. Categories of Stocks by Market Capitalisation

Based on market capitalisation, Indian listed companies are divided into three broad categories.

 Large Cap Stocks

  • Market Cap: ₹20,000 crore and above
  • Examples: Major banks, FMCG giants, technology leaders
  • Characteristics:
    • Well-established
    • Stable earnings
    • Consistent dividend payouts
    • Global or national brand recognition

 Mid Cap Stocks

  • Market Cap: ₹5,000 crore – ₹20,000 crore
  • Examples: Growing IT firms, regional players, expanding pharma companies
  • Characteristics:
    • Growth-oriented
    • Moderate volatility
    • May become tomorrow’s large caps

 Small Cap Stocks

  • Market Cap: Below ₹5,000 crore
  • Examples: Startups, niche manufacturers, emerging tech firms
  • Characteristics:
    • High growth potential
    • High volatility
    • Lower liquidity and higher risk

 5. Investor Profiles for Each Market Cap

 Large Cap Investors

  • Prefer security and predictability
  • Seek regular dividend income
  • Invest for long-term capital preservation

 Mid Cap Investors

  • Can tolerate moderate risk
  • Seek both growth and stability
  • Invest with a 3–5 year horizon

 Small Cap Investors

  • High risk appetite
  • Focused on exponential returns
  • Invest with a long-term vision (5–10 years)

 6. Risk vs. Reward: What Should You Expect?

  • Large Cap Stocks are less likely to fluctuate dramatically in price. However, they grow slowly.
  • Mid Cap Stocks experience higher swings but can deliver impressive returns when the economy supports them.
  • Small Cap Stocks may skyrocket in bull runs but suffer deep losses during downturns.

 Risk and reward are directly proportional to the market cap size.


 7. Role of Market Cap in Portfolio Diversification

Diversification is key to successful investing. Spreading your investments across various market cap categories can help reduce overall risk.

Example Portfolio:

  • 50% Large Cap: For stability
  • 30% Mid Cap: For growth
  • 20% Small Cap: For high return potential

This mix ensures that your portfolio weathers economic changes while capturing growth.


 8. Market Capitalisation and Mutual Funds

Mutual fund schemes often align their investment strategy with market cap:

  • Large Cap Funds: Invest 80%+ in large cap companies
  • Mid Cap Funds: Invest in mid-tier companies with strong growth
  • Small Cap Funds: Focus on young companies with high potential
  • Multi Cap Funds: Invest flexibly across all caps
  • Flexi Cap Funds: Similar to multi cap, but without restrictions

Choosing the right mutual fund depends on your investment horizon, goals, and risk appetite.


 9. How to Choose the Right Cap Category

Before investing, answer these:

  1. What is your risk appetite?
    • Low: Stick with large cap
    • Moderate: Add some mid cap
    • High: Mix in small caps
  2. What are your financial goals?
    • Capital protection: Large cap
    • Balanced growth: Mid cap
    • Aggressive growth: Small cap
  3. What is your investment horizon?
    • Short-term: Large cap
    • Medium-term: Mid cap
    • Long-term: Small cap
