Effect of buyback on F&O lot size.

I want to know if there is any impact on the lot size of the security in case of a buyback like it does due to a rights issue, bonus, etc.

don’t think buyback has any effect on f&o… maybe because there isn’t any changes happening like we see during dividends, rights issue, bonus, split etc… there’s also this nse article on f&o adjustment following corporate action but it doesn’t mention buyback… https://www.nseindia.com/products-services/equity-derivatives-corporate-actions-adjustments
