Shares of BSE declined as much as 5% to their day’s low of Rs 3,283 on the NSE on Monday after Wall Street major Jefferies downgraded the counter to 'underperform' from 'hold' and trimmed the target price to Rs 2,940 from Rs 3,520, a downside of 16% from current levels.
Jefferies flags risks to BSE’s revenue from domestic proprietary traders, who account for around 50% of notional turnover. It sees headwinds from the STT hike, RBI’s bank guarantee norms and the Closing Auction Session (CAS). BSE’s options average daily turnover in August 2026 so far is down 12% from July.
