What is NIFTY?

Nifty is a stock market index that represents the performance of large and actively traded companies listed on the National Stock Exchange (NSE). It was launched in 1996 to provide a picture of the overall market movement. It reflects how major sectors of the economy are performing through selected companies. Many investors and analysts track it to understand general market trends. Additionally, the nifty full form refers to the National Stock Exchange Fifty. This article covers what is Nifty and how it works. 

How does NIFTY work? 

NIFTY works by measuring the combined movement of selected top companies through a weighted calculation method. It changes based on stock price movements and market value. The process can be understood through these points: 

• It includes companies chosen based on liquidity and market size 
• Each company has a specific weight based on free-float market capitalisation 
• When share prices rise or fall, the index value moves accordingly 
• It is reviewed regularly to ensure the list stays updated 
• It is used as a benchmark for comparing portfolio performance 

How is NIFTY Calculated? 

The NIFTY 50 index is calculated using a method called "float-adjusted market capitalisation weighting." This means the value of the index reflects the total market value of the stocks in it, based on their market capitalisation (the total value of all shares in a company). 

The base value of the NIFTY 50 index was set on November 3, 1995, with a starting value of 1000, and the total market value of the stocks in the index was ₹2.06 trillion at that time. 

The formula for calculating the index value is: 

Index value = Current Market Value / (Base Market Capital * 1000)  

When calculating the index, adjustments are made for corporate actions like stock splits or rights issues, which can affect the stock prices.

1. Economic indicators like GDP growth, inflation, and interest rates directly influence investor sentiment and corporate earnings, which impact the Nifty 50 index.

3. The performance of NIFTY 50 listed companies is driven by factors like demand, cost structures, and government policy, which directly affect the index. 
4. Foreign Institutional Investors (FII) Activity Large inflows of foreign capital can drive up stock prices, while large outflows can lead to a market correction or decline. 
5. Domestic Institutional Investors (DII) Activity Mutual Funds, Insurance Companies, and Pension Funds also influence market movements. Their buying or selling activity can significantly impact the NIFTY index.
