We often hear news of the stock markets rising or falling and touching new highs or lows. If you are an investor, such news can have a significant impact on your fortunes. Have you ever wondered how the stock market fluctuations are measured? There are so many companies listed on the market, and it is simply not possible to incorporate the value of all listed shares to determine stock market movements.

That is why we have market indices. Indices are constituted by companies that are most representative of the stock market. The companies are chosen, based on factors such as the market capitalisation and the volume of trading. The most common indices in India are the CNX Nifty and the Sensex.

The CNX Nifty (also called Nifty Fifty) is the index for the National Stock Exchange while Sensex is the index for the Bombay Stock Exchange.
