Weekly Expiry: Sensex mirrors Nifty's swings, but with milder spurts

The BSE Sensex ended at 78,954.76 on Thursday, mirroring Nifty’s recent swings during its weekly expiry. Traders said these unusual moves are the new normal until liquidity improves. Samir Doshi noted, "Sensex options witnessed an unusual spike in implied volatility to 41-42% during the day," making trading difficult for option writers.
