The BSE share price fell more than 4 percent from its intraday high after the exchange itself acknowledged that its Closing Auction Session, introduced on 3 August, has led to lower trading volumes. The disclosure adds to a series of concerns that have weighed on the stock in recent weeks, including brokerage downgrades from Jefferies and Nuvama that specifically flagged CAS-related risks to the exchange’s derivatives volumes.<\/p>\n<\/div>\n

The BSE share price<\/a> fell more than 4 percent from its day’s high after the exchange disclosed that its Closing Auction Session, or CAS, mechanism has led to lower trading volumes. The admission from the exchange itself adds weight to concerns that brokerages have been flagging about the impact of this market-structure change on BSE’s business.<\/p>\n

This is not the first sign of pressure on the BSE share price tied to CAS. Global brokerage Jefferies had earlier downgraded the stock, citing concerns around the closing auction session alongside a higher securities transaction tax and revised RBI bank-guarantee norms, while Nuvama Institutional Equities also downgraded the stock to Hold, specifically citing CAS’s impact on options volumes.<\/p>\n
