Understanding Market Capitalisation
Market capitalisation (market cap) represents the total value of a company’s outstanding shares in the market. It is calculated by multiplying:
Total number of outstanding shares × Current share price
Example
If Company A has 1 crore shares trading at ₹20 each,
its market value = 1 crore × ₹20 = ₹20 crore.
Market cap rises or falls depending on share price movements, which are influenced by business performance, market sentiment, and broader economic trends.
Why Market Cap Rises or Falls
Reasons for Increase
- Strong earnings and financial performance
- Positive news or policy support
- Bullish market sentiment
- High demand for shares
Reasons for Decline
- Weak quarterly results
- Negative news, regulatory concerns
- Economic slowdown or global uncertainty
- Market sell-off or profit booking
Impact of Market Cap Changes
On Companies
- A higher market cap improves a company’s ability to raise funds, secure loans, and acquire other businesses.
- A declining market cap may reduce investor confidence and limit the company’s financial flexibility.
On Investors
- When market cap rises, investor wealth grows as share prices appreciate.
- A fall in market cap may lead to losses and trigger selling pressure.
Market Outlook
With benchmark indices ending higher this week, market analysts expect optimistic momentum to continue, supported by strong domestic growth, rising retail participation, and increased global investor interest in Indian equities.
However, volatility is expected in sectors such as telecom and IT due to global macroeconomic trends, currency movements, and competitive pressures.
