Nifty 50 is an important index of the Indian stock market. It tracks 50 large firms listed on the National Stock Exchange. These companies cover banking, technology, energy, cars, health care and daily necessities. The index is based on the moves in their share prices. This makes the index a simple way to look at the tone of a large part of the market.
What does the index say?
The Nifty 50 does not give equal weightage to each stock. It uses free-float market capitalisation approach. Free float is shares available for public trading. Shares held by promoters or locked owners do not form part of this count.
A high public market value of a company results in a high weight. Its price movement can move the index many points. A stock with a small weight has a small impact. So the index can go up even if lots of stocks fall. This can be caused by a few high-weight stocks posting gains.
The index list is reviewed in March and September. Stocks have to satisfy set rules on size, trading volume and market access. This keeps the list tied to active companies.
How stock movements affect Nifty 50?
The process is written in five steps:
1. Stocks Move Up or Down
The live price of each index stock is set by buy and sell orders. News, demand and supply can change that price during the day.
2. Each Price Move Gets Its Weight
The index uses a fixed weight for each stock. A heavy bank, with a one per cent rise, can add many index points. In a low-weight stock the same increase may add only a few points.
3. Sector Movements Matter
Sector stocks may respond to the same event . Change in rates can affect banks. A rupee move could be negative for tech companies earning from abroad. Rising crude oil may impact oil, paint, airline and transport companies. The index brings all these moves together into one value.
4. Moods are made by the news
Market views can change on company results, tax rules, policy news, inflation, rates and world events. If the news affects many stocks in the index, then the Nifty 50 may show a clear movement.
5. The Close Demonstrates the Net Result
All 50 stocks are weighted and gains and falls are tallied at market close. The last index value reflects the net result for the day.
Bank stocks and tech stocks may rise – but energy stocks could fall. If the stocks that gained have enough weight, the index can still close in the green.
What are Nifty Futures used for?
Nifty futures are derivatives based on Nifty 50 index. They are traded on the exchange and have a fixed expiry date. The price depends on the spot index , the time to expiry , the cost of funding , the expected cash payouts and the demand .
The futures price can be either above or below the spot index. This gap is known as the basis. A positive basis is a spread over the index. A negative basis is a hole underneath it. As expiry approaches the gap tends to close.
Nifty futures also react to market news and views. Readers tend to follow the spot index, futures price, trade volume and open interest as a package. Open interest is the number of contracts that are still open and not closed out. These data points represent trade action. They don’t prove where the index is headed next.
How to Read a Market Move
First, observe the point and percentage change of Nifty 50. Then look at what sectors drove the move up or down And then look at the high-weight stocks. See also market breadth. Breadth is the number of stocks that were up and down.
