Options turnover sinks at Dalal Street's top exchange preparing for IPO

India's stock exchange has seen options turnover plummet to its lowest in a year, a direct consequence of newly enforced trading regulations and the adoption of a closing auction system. Cash equities trading has also dipped, marking its lowest since November. This downturn poses a significant challenge for the upcoming initial public offering by the NSE, as traders recalibrate their strategies to align with the modified auction process.
