On January 26, 2026, domestic equity markets witnessed mild volatility ahead of the weekly derivatives expiry. Investor sentiment remained guarded as select stocks entered the Futures & Options (F&O) ban list due to elevated derivative open interest.
The Nifty weekly Futures & Options contracts are scheduled to expire today, Tuesday, January 27, 2026, in line with the regular weekly expiry calendar.
Ahead of the Nifty’s weekly expiry on January 27, 2026, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban.
This restriction is triggered when the open interest in a stock’s derivative contracts exceeds 95% of the Market-Wide Position Limit (MWPL). While fresh derivative positions are restricted, trading in the cash market continues as usual.
As of January 23, 2026, Sammaan Capital Limited’s share price ended lower in the cash market.
The stock opened at ₹140.87 against a previous close of ₹139.97 and moved within a day’s range of ₹138.52 to ₹142.75.
It eventually closed at ₹138.91, recording a decline of ₹0.62 or 0.44% for the session.
A stock is placed under the Futures & Options (F&O) ban by the NSE when the open interest in its derivative contracts exceeds 95% of the Market-Wide Position Limit (MWPL).
The objective of this regulatory measure is to curb excessive speculation and maintain orderly market conditions, particularly during expiry sessions.
During the ban period:
Nifty 50 Futures & Options contracts typically expire every Tuesday. All contracts are settled based on the closing price of the underlying index on the expiry day.
Weekly expiry sessions often witness heightened volatility due to position unwinding and rollover activity.
