CAS U-turn ahead? BSE, Groww, NSE, other capital market stocks jump up to 4% amid buzz around Sebi tweaking F&O settlement rules

What happened: SEBI will likely stop using closing auctions to calculate derivatives settlement prices for at least one year, using the volume-weighted average price of the last 30 minutes instead, per Reuters. Why it matters: Jefferies said CAS issues appear to be easing, with options volumes recovering in September after an August drop, and named Groww, MCX, KFIN and Nuvama as top capital market picks. The changes would partly reverse mechanisms introduced to set closing prices.
