How Does FINNIFTY Work?
FINNIFTY is calculated in real time during market hours using the free-float market capitalisation methodology.
- Selection of Companies: Includes top financial firms from the Nifty 500 based on sector classification and liquidity criteria.
- Free-Float Market Cap Method: Only publicly tradable shares are considered, excluding promoter and government holdings.
- Weight Based on Size: Larger companies like HDFC Bank and ICICI Bank have a bigger impact on index movement.
- Weight Limits Applied: No single stock exceeds 33%, and the top three together cannot cross 62%.
- Periodic Rebalancing: The index is reviewed and adjusted twice a year to reflect market changes.
- Tradable via Derivatives: Investors can trade FINNIFTY through futures and options, with weekly expiry on Tuesdays.
What Is the Expiry of FINNIFTY?
In 2026, FINNIFTY Futures and Options (F&O) contracts expire on the last Tuesday of every expiry month. If the scheduled expiry day is a trading holiday, the contract expires on the previous trading day.
Key FINNIFTY Expiry Rules
- Expiry frequency: Monthly
- Expiry day: Last Tuesday of the expiry month
- Holiday rule: If the last Tuesday is a trading holiday, the expiry shifts to the previous trading day.
- Settlement: Cash settled
- Lot size: 60 units per lot
The monthly expiry schedule follows the standardised equity derivatives framework introduced by SEBI, under which the NSE retains weekly expiries only for its benchmark index, while FINNIFTY derivatives are available with monthly expiries.
What Is the FINNIFTY Lot Size?
As of 2026, the FINNIFTY lot size is 60 units. This means every FINNIFTY Futures or Options (F&O) contract represents 60 units of the underlying index, and all trades must be placed in multiples of 60.
Key Points About the FINNIFTY Lot Size
- Trading quantity: Orders must be placed in multiples of 60 (60, 120, 180, and so on).
- Contract value: It depends on the prevailing FINNIFTY index level and is calculated by multiplying the index value by the lot size.
- Margin requirement: Traders do not pay the entire contract value upfront. The required margin or option premium depends on the contract type and the broker’s margin requirements.
How to Invest in FINNIFTY?
Investors cannot invest in the FINNIFTY index directly. However, they can gain exposure to it through FINNIFTY Index Funds, Exchange Traded Funds (ETFs), Futures and Options (F&O), or by purchasing the underlying constituent stocks individually.
Invest Through FINNIFTY Index Funds
Investors can invest in index funds that aim to track the FINNIFTY index by replicating its constituent stocks and weightages. Depending on the scheme, investments can be made through a lump sum or a Systematic Investment Plan (SIP).
Invest Through FINNIFTY ETFs
Exchange Traded Funds (ETFs) that track FINNIFTY are listed on the stock exchange and can be bought or sold during market hours through a Demat and trading account. Their objective is to closely mirror the performance of the index.
Trade FINNIFTY Futures and Options
FINNIFTY is also available in the Futures and Options (F&O) segment of the NSE. Traders can take positions using futures contracts or call and put options based on their market outlook. FINNIFTY derivative contracts are cash settled, with weekly contracts expiring every Tuesday.
Build a Portfolio Using FINNIFTY Stocks
Investors may also choose to purchase the individual stocks that make up the FINNIFTY index. This approach requires buying and managing the constituent companies separately rather than tracking the index through a single investment product.

While NIFTY 50 tracks the performance of the 50 largest companies across multiple sectors listed on the NSE, FINNIFTY focuses only on 20 companies from India’s financial services sector, such as banks, NBFCs, insurance companies and housing finance firms.
