  "account": "On the day of the inaugural index rebalancing, the National Stock Exchange of India (NSE) saw a remarkable turnover of Rs 39,718 crore in its Closing Auction Session (CAS), constituting 22% of its total cash market turnover. This marked a significant milestone as the mechanism, introduced by the Securities and Exchange Board of India (SEBI) on August 3, demonstrated its value to investors. NSE held a commanding 99.9% market share in the CAS, with over 98,000 unique investors actively participating in the session.

This aims to bolster transparency, integrity, and fairness in determining closing prices for stocks whose derivative contracts are available. The introduction of the CAS aligns the Indian market more closely with global practices for closing price discovery.",
