Revised downwards (new lot size is not a multiple of the old lot size)
The lot size for these nine stocks has been revised downwards. However, the new lot size is not a multiple of the previous lot size. To avoid any operational issues, the revised market lots will apply only to January 2027 and subsequent expiry contracts.

What’s applicable for the revised lot sizes (Annexure 2 & 4)?
To avoid any operational complexities, here’s how the changes will be implemented:
Only the far month contracts, that is, the January 2027 expiry contracts, will have the revised market lots.
November 2026 and December 2026 contracts will continue with the existing lot sizes.
All subsequent contracts (January 2027 expiry and beyond) will reflect the new market lots.
The day spread order book will not be available for the December 2026 to January 2027 combination contracts.
For the computation, NSE has considered the average closing price of each underlying for the period between September 1 and September 30, 2026.
