BSE shares dropped over 4% on August 17 as brokerage firm Jefferies downgraded the stock to 'Underperform' and cut its price target by 16%. The report cited concerns over falling trading volumes, new regulatory changes, and a slowing pace of market share growth. Investors are now watching how new trading norms, including RBI's bank guarantee rules, may affect the exchange's future earnings.
BSE shares saw a sharp decline on Monday, August 17, falling by more than 4% following a negative report from global brokerage firm Jefferies. The firm changed its rating on the exchange to 'Underperform' from 'Hold' and significantly lowered its price target to Rs 2,940 from Rs 3,520.
Alongside the price target reduction, Jefferies also trimmed its earnings per share estimates for the 2027 to 2029 financial years by 5% to 12%. This revision reflects a more cautious outlook on the exchange's ability to maintain its recent earnings trajectory.
Volume Risks and Regulatory Headwinds
The primary reason for the downgrade is the expectation of pressure on trading volumes. Jefferies noted that BSE’s options average daily turnover for August 2026 has already fallen 12% compared to July 2026. The brokerage highlighted several factors that could hurt trading activity, including a potential increase in the Securities Transaction Tax, new bank guarantee regulations from the Reserve Bank of India, and the impact of the newly introduced Closing Auction Session.
A significant risk factor pointed out by the brokerage is BSE’s heavy reliance on domestic proprietary traders, who contribute roughly 50% of the exchange's total trading value. If these traders reduce their activity due to regulatory changes or shifting market conditions, the exchange's revenue could be affected.
Slowing Market Share Expansion
The report also suggests that the rapid market share growth previously expected by some investors is losing momentum. Jefferies noted that outside of specific trading cycles like T-0 or T-1 settlement days, the pace of gains has decelerated. Additionally, the exchange’s market share during expiry day trading is now largely comparable to the National Stock Exchange, indicating increased competition.
At the time of the brokerage report, BSE was trading at approximately 44 times its one-year forward earnings. This valuation level implies that the stock is sensitive to any signals that growth may be slower than previously anticipated. The key monitorable for shareholders will be the monthly volume data, the actual impact of the new trading norms on trader participation, and management's commentary in the upcoming quarterly earnings call regarding these operational changes.
