At that time, the call option (CE) at the 76,600 strike was priced at ₹152, while the put option (PE) was priced at ₹95. However, by the time the Closing Auction Session (CAS) ended at 3:30 PM, the Sensex had fallen to 76,152. This sharp decline reduced the value of the call option to zero, while the put option priced at ₹95 jumped directly to ₹446. This sudden change resulted in huge profits for put buyers, while call writers and sellers suffered significant losses. What is CAS and how does it work? CAS was introduced in the Indian stock market on August 3 this year. New rule: It is a short auction session held around market closing, running until approximately 3:40 PM. During this session, buy and sell orders are matched to determine the official closing price of stocks. Old rule: Previously, the closing price was calculated using the volume-weighted average price (VWAP) of the last 30 minutes, from 3:00 PM to 3:30 PM. Global Practice: Regulators have implemented this new system to bring Indian markets in line with the standards of Asian and global markets such as China, Taiwan, Hong Kong, and South Korea.
