Changes in Stock Derivatives Expiries: Are there any?
The expiration dates of stock-specific derivatives remain the same. Both NSE and BSE continue to apply the last-Thursday-of-the-month rule. If it falls on a holiday, the date moves to the very previous business day.
Rollout Schedule and New Expiries Strategies
Both BSE and NSE guarantee a smooth transition for traders on their derivative contracts. For BSE indices new settlement days come effective starting January 1, 2025. All new weekly, monthly, quarterly, and semi-annual contracts should align. To ensure a gradual rollout schedule it is allowed for the old contracts (aired before January 1) to follow the old rules. This continues until the contracts expire naturally.

Changes in Contract Specifications: Are there any?
The only question that should bother you is ‘Friday is the expiry day of which index?’ Although expiration days are shifted, all other contract specifications remain untouched. Check out some examples:
- No difference between the strike price for Sensex and Bankex (for example, 100 points, or 200 points based on underlying level and derivatives market conditions).
- Lot sizes for index futures and options contracts are the same (for example, 10 units per lot for Sensex futures and 15 units per lot for Bansex futures).
- The initial, span, and exposure margins are unchanged. Contracts are cash-settled unless specified differently. The settlement price is based on the underlying stock/index on the last trading day. The automatic exercise rule applies.

Are the Changes Important to Derivative Contract Traders?
With new settlement rules in the air, traders need to adjust their strategies accordingly.

Instead, traders should apply more precise timing for initiation and closure of hedges.
