What is Nifty 100?

The Nifty 100 is a stock market index in India that represents the performance of the top 100 companies listed on the National Stock Exchange (NSE). It is one of the key benchmark indices used to gauge the overall health and direction of the Indian stock market. The Nifty 100 is a diversified index, comprising companies from various sectors such as banking, information technology, pharmaceuticals, energy, and manufacturing. Fund managers, traders, and analysts often use Nifty 50 as a benchmark to evaluate the performance of their portfolios and make informed investment decisions.

Which stocks are included in Nifty 100?

The Nifty 100 index comprises the top 100 companies listed on the National Stock Exchange (NSE). It undergoes periodic rebalancing, with stocks being included or excluded depending on criteria such as market capitalisation, liquidity, and sector representation.

How is Nifty 100 calculated?

When determining the Nifty 100, the market value of each company is found by multiplying its share price with the total equity. To refine this, the equity is multiplied by the share price to calculate the free-float market value, adjusting for the Investable Weight Factor (IWF) that reflects actively traded share proportions.

The Nifty 100 is computed using a starting point of 1,000 as its base value. The daily index value is established by dividing the current market value by the product of the base market capital and the base value of 1,000. This calculation accommodates changes resulting from corporate actions like rights issues, bonus issues, stock splits, and more.

In essence, the Nifty 100 Index mirrors the combined market values of its top 100 companies, considering free-float and IWF. The calculation, based on a base value of 1,000, ensures an ongoing representation of the collective performance of these companies in the stock market, factoring in changes in valuations and corporate actions.
