Stock F&O monthly expiries
Tue, 25 Aug, 2026 in 7 daysTue, 29 Sept, 2026 in 42 daysTue, 27 Oct, 2026 in 70 days
All single-stock futures and options share this monthly cycle; stock contracts are physically settled.
What actually happens as a contract expires
Trading in an expiring contract continues through its final session, and the settlement price is determined from the underlying's closing values rather than the derivative's last trade — for index products, from the index's closing computation in the final half hour. Index futures and options settle in cash: the difference between your position price and the settlement value moves through your account, and the position simply ceases to exist.
Stock derivatives are the sharper edge. Since they settle physically, an in-the-money stock option carried into expiry becomes a delivery obligation — shares to deliver or take delivery of, at full contract value, not premium value. Brokers ramp margins on in-the-money stock options through expiry week precisely because a ₹15,000 option position can quietly become a ₹15 lakh delivery obligation. Anyone not intending delivery closes stock option positions before the final session.
Rollover, and why expiry weeks feel different
Positions that want to persist past expiry must be rolled — the near-month contract closed and the next month opened, paying the spread between the two. Rollover activity concentrates in the last few sessions of a series, which is why volumes and open interest migrate visibly to the next month in expiry week, and why the ban list matters more then: a banned stock cannot be rolled at all. Expiry days themselves tend to bring the heaviest index-option volumes of the week, concentrated in strikes near the trading level.
Expiry questions
What happens on expiry day?
Every contract for that expiry settles: index derivatives settle in cash against the closing value, while stock derivatives are physically settled — in-the-money positions result in delivery obligations. Positions not closed before expiry settle automatically at the exchange-determined price.
Why did expiry days change?
SEBI rationalised the weekly-expiry calendar so each exchange runs a single benchmark weekly expiry, and exchanges have since moved their designated days. This page reads the dates from the exchange’s own contract file each evening, so it reflects whatever the current regime is rather than a remembered rule.
Do all stocks share one expiry?
Yes — single-stock futures and options follow one monthly cycle, expiring together on the month’s designated day. Only the index products carry weekly expiries.
When is this calendar updated?
Every evening, from the day’s FO bhavcopy published by NSE. The as-of date is shown on the page.
Can an expiry date change after a contract lists?
Yes — exchanges shift an expiry by circular when it collides with a newly declared holiday. Because this page reads the live contract file rather than a fixed rule, such changes appear here automatically the next evening.
Why close in-the-money stock options before expiry?
Stock F&O settles physically, so an ITM option held through expiry becomes a share delivery obligation at full contract value, with margins raised through expiry week. Traders wanting only the price exposure exit before the final session.
