Introduction to Stock Market Indices

Before comparing sensex vs nifty, it is important to understand what a stock market index actually is.

A stock market index is a collection of selected stocks that represents the overall performance of a market or a segment of the market. Instead of monitoring thousands of stocks individually, investors can simply track an index to understand market direction.

Indices serve several purposes:

• Measure market performance
• Help investors compare returns
• Track economic growth
• Guide investment decisions
• Form the basis of index funds and ETFs

In India, the two most popular indices are Sensex and Nifty.

Sensex stands for the Stock Exchange Sensitive Index. It is the benchmark index of the Bombay Stock Exchange (BSE).

Introduced in 1986, Sensex consists of 30 large and financially strong companies listed on the BSE.

• Managed by BSE
• Reflects market sentiment

What is Nifty?

Nifty is the flagship index of the National Stock Exchange (NSE). It is officially known as the Nifty 50 because it comprises 50 major companies.

Launched in 1996, Nifty has become one of the most tracked indices in India.

Key Features of Nifty
