Nifty Next 50 Index: What It Tracks and How It Works

The Nifty Next 50 index contains the Nifty 100 companies that remain after the Nifty 50 companies are removed. It tracks a different basket from the Nifty 50, with different company and sector weights. The definition is more precise than calling it a list of companies ranked immediately below the largest shares.

NSE Indices maintains the benchmark. It is a calculated index, so you cannot buy an index point directly. Exposure comes through a product such as an index fund, an exchange-traded fund (ETF), or a derivative contract. Those products have different costs and risks.

How it differs from Nifty 50

The familiar description of this index as part of the large-cap universe can be useful, but it should not replace the actual index rules. Nifty 50 membership involves eligibility and liquidity checks. Do not assume that the Next 50 is simply a daily ranking of every company's full market value. The Nifty 50 guide explains the related benchmark.

How many companies, and how much of the market

The index has 50 companies. They are the Nifty 100 companies that are not in the Nifty 50, and the index is weighted by free-float market capitalisation (company value counting only the shares open to public trading). NSE's index page said that, as of 30 March 2026, the Next 50 represented about 11.22% of the free-float market value of the stocks listed on NSE. Treat that as a dated snapshot, because it moves with prices and with each review.

So the Next 50 is a basket of large companies that sit outside the Nifty 50, and not the whole mid-cap market. For the next layer of companies see the Nifty Midcap 100 guide, and for the full Nifty 100 basket see the Nifty 100 page.

Nifty 50, Nifty Next 50 and Nifty 100 side by side

Because the baskets do not overlap, a company that moves up out of the Next 50 into the Nifty 50 changes both indices at a review. Index funds that follow each basket then buy or sell shares on the effective date, which is one reason the closing prices around a review date can be unusual.

Weights, membership and changes

Free float means shares treated as available for public investment. A free-float-weighted index gives companies different weights rather than giving every constituent an equal share. The official methodology also includes caps for constituents without stock derivatives. The number of company names alone cannot tell you where the basket's exposure is concentrated.

The factsheet describes a semi-annual review cycle, meaning reviews every half-year. Membership can also be affected by corporate changes. Before using a constituent list, the list of companies in the index, check its effective date. An announced replacement may not yet have taken effect. A remembered list of familiar company names can quickly become misleading.

Use the official overview's constituent download and the dated factsheet linked below. Compare the document date with the date of your analysis. For a broader basket, see the Nifty 500 index guide. Market capitalisation, meaning company value from its shares, is explained in the market capitalisation glossary.

Why the Next 50 can move differently from the Nifty 50

The two baskets hold different companies and different sector mixes, so on any given day they can move by different amounts and sometimes in different directions. A fall in the biggest banks moves the Nifty 50 more than the Next 50 because banks are a larger part of the Nifty 50. The reverse can be true for sectors that matter more in the Next 50. To see the sector split, open the NSE factsheet and read the sector table with its date.

Do not assume the Next 50 is safer or riskier. Compare matched periods (the same start and end dates) for the two indices, and look at falls and recoveries, not just the final return. A fund that tracks it is exposed to every one of those moves.

What happens at a review

At each semi-annual review NSE Indices may add and remove companies. If you hold a fund, you do not need to act, because the fund manager adjusts the portfolio. If you hold a futures or options contract, its underlying stays the index, so a review only changes the index value.

Index points and ETF unit prices are different

Consider a made-up index move from 70,000 to 73,500. The percentage increase is (73,500 / 70,000 minus 1) × 100 = 5%. Those levels are illustrative; they are not current market quotes. Comparing raw point levels of different indices tells you neither which basket is cheaper nor which will perform better.

Now suppose a fictional ETF unit costs ₹500. An assumed ₹1,00,000 purchase buys 200 units before charges. If you later sell those units at an assumed ₹525, the gross sale value is 200 × ₹525 = ₹1,05,000 and the gross gain is ₹5,000. The unit-price change is also 5%.

The ETF prices in that example are separate assumptions. A live fund need not match an index's percentage move exactly over your holding period. Check the fund's own documents, its costs and the prices available when you trade. The example excludes transaction charges and tax, so its gross gain is not a final amount you keep.

Cost of owning a fund: a small yearly charge adds up

An index fund or ETF charges an annual expense ratio, taken from the fund's assets. Take an assumed 0.5% a year on a ₹1,00,000 holding. That is 1,00,000 × 0.005 = ₹500 a year, whatever the market does. The fund's real ratio is in its documents, and the difference between the fund's return and the index return is called tracking difference. Compare both numbers for two or three products before you choose.

For the difference between the two product types, read index fund vs ETF and the glossary entries for index fund and ETF. An ETF also has a bid-ask gap, so buy and sell with a limit price where your broker allows it.

Ways to get exposure

• Index fund: a mutual fund intended to track the benchmark; read the scheme documents and the applicable purchase and redemption terms.
• ETF: a fund traded on the exchange; inspect its traded price, available buyers and sellers, and fund disclosures.
• Futures and options: NSE lists NIFTYNXT50 contracts on a monthly cycle. Contract availability does not establish a narrow trading spread or an easy exit.

As checked on 16 Oct 2026, NSE's specifications describe monthly futures and options for this index. Weekly options are not listed in that cycle. Before trading a derivative, confirm the contract, expiry and quantity from current exchange information. A fund purchase and a leveraged derivative position cannot be treated as interchangeable exposure.

For a fund comparison, read index fund versus ETF. Keep the benchmark question separate from the product question: tracking the same index does not give products identical costs, trading conditions or outcomes.

Nifty Next 50 futures and options: lot size and expiry

NSE lists futures and options on NIFTYNXT50. In the contract data this site follows, the lot size is 25 units, as of the Oct/Nov 2026 contract list. Lot sizes are revised by the exchange from time to time, so read NSE's current lot size file before you plan a position. Never carry a quantity from an old article.

Expiry is monthly only, with no weekly series. The monthly expiry falls on the last Tuesday of the month, and if that day is a trading holiday, it moves to the previous trading day. The lot size and expiry calendar lists the dates, and weekly vs monthly expiry explains the difference.

Notional value is the full value of the contract, which is the index level times the lot size. Using a made-up index level of 70,000, one lot has a notional of 70,000 × 25 = ₹17,50,000. You do not pay that amount upfront, since margin is only a part of it. But your profit and loss move on the full notional. See notional value for the idea.

• Use limit orders and check the bid-ask gap, because contracts with lower volume can have wide gaps.
• Do not compare it with Nifty options. Nifty has weekly expiries, while the Next 50 has only monthly ones.
• Keep stock and index lots in separate lines in your journal so the quantity is always the real lot size.

Questions about the Nifty Next 50

Journaling index fund and derivative trades

OneTradeJournal is a manual journal. You enter each trade yourself, with the reason, stop, target and emotion. That works for an index fund purchase too: write the date, the amount, the product and why you chose it over the Nifty 50. For derivative trades, the app estimates charges per trade, and you can compare the estimate with your contract note. The free plan allows one trade a day per market, which is enough for a slow, rules-based approach.
