The Nifty weekly derivatives contracts are scheduled to expire on Thursday, August 7, 2025, in line with the standard weekly cycle. Caution ahead of expiry has resulted in tempered market sentiment.
Ahead of the Nifty’s weekly expiry on Thursday, August 7, 2025, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban:
This restriction is enforced when the open interest in the stock crosses 95% of the market-wide position limit (MWPL). While fresh derivative positions are disallowed, the stock continues to be available for trading in the cash market.
The stock under the F&O ban for August 7 is:
On August 6, PNB Housing Finance stock closed at ₹774.80, up from its previous close of ₹767.80. It opened at ₹772.20 and moved between an intraday high of ₹785.70 and a low of ₹766.50. The Volume Weighted Average Price (VWAP) stood at ₹777.71.
Trading volumes remained strong, with 48.17 lakh shares exchanged, generating a traded value of ₹374.66 crore. The company's total market capitalisation was reported at ₹20,132.96 crore, with a free float market cap of ₹12,372.15 crore. The percentage of deliverable quantity to traded quantity stood at 38.56%, and the applicable margin rate was 36.50%.
A stock is placed under the F&O ban list when open interest exceeds 95% of MWPL, as per NSE guidelines.
During the ban:
This safeguard is meant to curb speculation and ensure orderly market function during high-activity periods like expiry days.
The Nifty 50 F&O contracts expire every Thursday, unless it’s a trading holiday (in which case, expiry moves to the prior session). Settlements occur at the day’s closing price.
For ease of tracking, expiry contracts may appear under the monthly header on trading platforms during expiry week.
