What is Market Capitalisation?
Market capitalisation is share price multiplied by shares outstanding. It buckets companies into large, mid, and small cap with different liquidity and volatility profiles.
Formula
Market Cap = Stock Price × Shares Outstanding Example: Reliance Industries Stock Price: ₹2,900 Shares Outstanding: 676 crore Market Cap = 2,900 × 676 crore = ₹19.6 lakh crore ($235 billion) Market Cap Changes: If price rises 10% to ₹3,190 New Market Cap = ₹21.6 lakh crore Note: Market cap changes only with price (or if company issues/buys back shares)
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Market Capitalisation shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Best practices

- Log rejected orders — they reveal unrealistic limit discipline.
- Review slippage in R-multiples, not only rupees.
Common pitfalls
- Chasing with market orders after Market Capitalisation already moved.
- Using limits on fast Bank Nifty breaks without timeout rules.
- Not recording partial fills — skews performance stats.

Swing trading captures multi-day moves between support and resistance or trend legs, with wider stops and fewer trades than intraday styles.

FAQ
What is market cap in simple terms?
Market cap is what the stock market says a company is worth. If a company has 10 crore shares at ₹100 each, its market cap is ₹1,000 crore. It's the price to buy the entire company at current share price.
How is market cap calculated?
Market Cap = Stock Price × Total Shares Outstanding. If TCS trades at ₹3,500 with 366 crore shares, market cap = ₹3,500 × 366 crore = ₹12.8 lakh crore.
What is large cap, mid cap, and small cap?
In India: Large cap = top 100 companies (above ₹30,000 crore). Mid cap = 101-250 (₹10,000-30,000 crore). Small cap = 251 and below (under ₹10,000 crore). Definitions vary and change with market levels.
Is market cap the same as company value?
Market cap is equity value only. Enterprise Value (EV) includes debt and excludes cash—a more complete picture for acquisitions. A company with ₹100 crore market cap and ₹50 crore debt has EV of ₹150 crore.
Why is market cap important?
Market cap determines index inclusion, fund mandates, and liquidity. Large caps are stable but slower growing; small caps are volatile but can grow faster. Your risk tolerance guides which to trade.
