The NIFTY 50 is an index of the Indian stock market which includes the stocks of 50 large, liquid companies listed on the NSE. The index was introduced on 21 April 1996 and has the base date of 3 November 1995, at which time its base level was set to 1,000. Any increase or decrease in the Nifty Index reflects changes in investor sentiments about India's leading companies.
Types of NIFTY Indices
Besides the main NIFTY 50, NSE Indices Limited runs several sub-indices that track specific sectors or market segments.
NIFTY Bank
Also called Bank Nifty, this tracks the 12 most liquid, large-cap banking stocks on the NSE. It's widely used as a benchmark for the banking sector and is one of the most actively traded indices in India's derivatives market.
NIFTY IT
Tracks the leading information technology companies listed on the NSE. It's closely watched given IT's large share of India's export economy.
NIFTY Next 50
Covers the 50 companies ranked just below the NIFTY 50 by market capitalisation. It's popular with investors looking for the next generation of large-cap stocks.
NIFTY Financial Services
Banks, NBFCs, insurance, and other financial companies – a larger selection than the NIFTY Bank index alone.
NIFTY Midcap 50
Consists of medium-sized companies based on market cap, thus diversifying from the largest companies.
Every sub-index has its own objective – futures and options traders keep an eye on NIFTY Bank, whereas long-term investors might consider NIFTY Next 50.
Who Owns and Manages NIFTY 50?
NIFTY 50 is owned and managed by NSE Indices Limited, formerly known as India Index Services & Products (IISL). This company decides which stocks qualify for the index, reviews the composition regularly, and maintains the official methodology.
Not every NSE-listed company qualifies. To be included, a stock must meet strict rules:
Domicile and listing
The company must be domiciled in India and listed on the NSE. Foreign companies listed via Indian Depository Receipts don't qualify.
Free-float market capitalisation
The stock must rank among the largest by free-float market cap, the value of shares actually available for public trading, excluding promoter holdings.
Liquidity
The stock must have an average impact cost of 0.50% or less for 90% of trading days over the past six months, for a ₹10 crore portfolio. Impact cost measures how much price moves when a large order is placed.
Trading frequency
The stock must have traded on at least 90% of trading days in the past six months.
Listing history
A minimum of six months' listing history is required, though a three-month track record may be accepted for strong IPOs.
Stocks that stop meeting these criteria can be dropped in future reviews.

How is the NIFTY 50 Index Calculated?
NIFTY uses a free-float market capitalisation-weighted method. This means larger companies with more publicly available shares influence the index more than smaller ones.
Formula:
Index Value = (Current Market Value of all 50 stocks ÷ Base Market Capital) × 1,000
Steps:
- Calculate the free-float market cap of each of the 50 stocks (share price × shares available for public trading, excluding promoter holdings).
- Add these values to get the total current market value.
- Divide by the base market capital, the total free-float market cap of these stocks on 3 November 1995.
- Multiply by 1,000 (the base index value) to get the current NIFTY level.
Since it is a weighted formula, a larger corporation such as Reliance Industries would have a much greater effect on the index than a smaller company even if there is an equal percentage increase or decrease. The market capital base figure is also revised in light of any corporate activities like stock split, bonus shares issue, etc.
NSE Indices Limited reviews the index composition twice a year - in March and September. Underperforming stocks may be replaced by ones that better meet the eligibility criteria. When a stock is added, index funds must buy it, which can push its price up temporarily; the opposite happens when a stock is removed. Removal doesn't necessarily mean the company is a bad investment - it simply no longer meets the index's current thresholds.
