What is Sensex?
Known as the Sensitive Index, the Sensex is a stock market index of the Bombay Stock Exchange (BSE). With an underlying value of 100, Sensex is a market-weighted stock index that includes the stocks of the top 30 reputable companies, based on their financial strength and performance. Additionally, Sensex is calculated using the free-float market capitalization method, and the performance of 30 selected stocks is directly reflected by the index grade.
The percentage of all shares issued by companies that are available to the public to trade in the market is known as the freely transferable market capitalization. In the free-floating market capitalization method, the market value of all 30 stocks selected, relative to a reference period, is reflected by the index. Sensex is calculated first by determining the market capitalization of each of the 30 companies, and then multiplying it by a free-floating coefficient, providing a free-floating market capitalization. It is then divided by the index divisor.

What is Nifty?
National Stock Exchange Fifty (Nifty) is the stock market index of the National Stock Exchange (NSE). Also known as NIFTY 50 and CNX Nifty, it consists of 50 stocks that are actively traded on the NSE and are owned and managed by India Index Services and Products Ltd. (IISL), a subsidiary of NSE.
In addition, the underlying value of the index is 1,000 and it is calculated using the free-floating market capitalization weighting method. Similar to Sensex, the first market capitalization is calculated by multiplying equity by the market price. To determine the floating cap, equity is multiplied by the price and again it is multiplied by the IWF (Investigated Weight Factor). Nifty is then calculated daily, by dividing the current market value by the underlying market cap and multiplied by the base index value of 1000.
