In the Indian stock market, an index is like a thermometer that tells you how a specific group of stocks is performing.

An index tracks the performance of selected stocks that represent a particular sector, exchange, or market segment. Instead of looking at thousands of individual stocks, an index gives you a quick snapshot of overall market health.

🏛️ Popular Stock Market Indices in India

1. Sensex (BSE Sensex)
Managed by: Bombay Stock Exchange (BSE)
Tracks: Top 30 financially strong and established companies from various sectors.
Examples: Reliance Industries, TCS, HDFC Bank, Infosys.

2. Nifty 50
Managed by: National Stock Exchange (NSE)
Tracks: Top 50 large-cap companies across 13 sectors.
Considered a benchmark for the Indian equity market.

These are the two benchmark indices in India. If they go up, it usually means most large companies are performing well—and vice versa.

📈 How Are Index Values Calculated?
Most indices in India are calculated using the free-float market capitalization method, which means:
Index value = (Market cap of selected companies) / (Base value)
Only shares that are available for trading (free-float) are considered—so government holdings or locked-in shares are excluded.

🧩 Why Are Stock Market Indices Important?
Benchmarking: Helps investors compare the performance of their portfolios.
Market Sentiment: A rising index usually means optimism; a falling one indicates caution or fear.
Investment Products: Many mutual funds, ETFs (Exchange Traded Funds), and index funds track indices.
Decision-Making Tool: Guides traders and analysts in understanding which sectors are driving the market.

BSE Smallcap – Represents smaller, high-growth companies.
