CAS chaos: Niftys indicative price drops 2% in 2 seconds, later recovers on monthly F&O expiry day

Nifty's indicative price sharply dropped by 2% during the closing auction session on monthly expiry day. The index fell from 22,684 to 22,249 within two seconds at 3:20:01. This sudden decline was followed by a rapid recovery, and it closed above the pre-CAS level. Typically, monthly expiry days bring heightened market volatility, contributing to such fluctuations. Overall, Nifty lost 64 points or 0.28% on that Tuesday.
