Adjustment of F&O contracts of ONGC due to dividend

As per the NSE circular, February 18, 2026, the strikes of ONGC options and the base price of the futures contracts will be revised due to extraordinary dividends.

Adjustment for future contracts:

All positions in futures contracts of ONGC will be marked-to-market on the last cum-dividend date, i.e. February 17, 2026, based on the daily settlement price of the respective futures contract. Subsequently, open positions will be carried forward at the daily settlement price less ₹6.25 (dividend amount) for the respective futures contract.

From February 18, 2026 (ex-dividend date), daily mark-to-market settlement of the futures contracts will continue as per normal procedures.

For example:

Assume you bought 1 lot (2250 quantities) of ONGC February futures on February 17, 2026, at ₹250, and the daily settlement price at market close is ₹260, you would have made a mark-to-market profit of ₹10 per share.

On February 18, 2026, the previous day’s position will be carried forward at ₹253.75 (i.e. 260 − 6.25). If the closing price on February 18, 2026, is ₹256, you’ll make a mark-to-market profit of ₹2.25 per share.

Adjustment for option contracts:

The full value of the dividend, i.e. ₹6.25, will be deducted from all the cum-dividend strike prices on the ex-dividend date. All positions in existing strike prices will continue to exist in the corresponding new adjusted strike prices.

For example:

The strike price of the ₹250 Call Option will be reduced to ₹243.75 on February 18, 2026, and the positions in the ₹250 Call Option will continue to exist in the ₹243.75 Call Option.

The lot size of the F&O contracts will not change.

Also, if you hold equity shares of ONGC in your Demat account as of February 18, 2026 (ex-date), you will be entitled to receive the dividend, which will be credited directly to your primary bank account within 30 to 45 days from the record date.
