What is an Index?

A stock index is a measurement of the changes that take place in the stock market. It measures price movement and market performance. For creating an index, one has to group some stocks from the list of stocks with similar characteristics. This grouping of stocks can be on the type of industry, total market capitalization or the size of the company. 

To calculate the value of the stock market index, one can use the values of the underlying group of stocks. Any change in the value of underlying stock also leads to a change in the stock index value. If the price of most of the stocks rises, the index will again rise and vice-versa. 

Thus, an index is indicative of changes in the market. It reflects the overall market investing sentiment and price movements. Investors and financial managers use this to measure the value of portfolio holding. They can also use it for comparing the performance with the benchmark index. 

Some of the standard indices in India are 
  • Benchmark indices like NSE Nifty and BSE Sensex
  • A broad-based index like Nifty 50, BSE 100, Nifty Next 50, etc.
  • Market capitalization indices like BSE Smallcap, BSE Mid Cap, Nifty Small cap, Nifty Mid Cap, etc.
