BSE Limited has witnessed a pronounced decrease in market value, losing nearly ₹30,000 crore over the past three months as three critical challenges simultaneously impact the exchange business. The stock has declined over 1% on Thursday, August 20, trading at ₹3,302.40 per share on the National Stock Exchange (NSE) at 2:39 pm. The exchange, which was one of the biggest stock market winners of the last two years, is now testing investor patience as options average daily turnover for August month-to-date was down 12% compared with July, according to Jefferies. The average daily premium turnover fell to ₹181 billion, down 22.7% week-on-week, representing the lowest level since January 2025, as reported by Nuvama.
Global brokerage Jefferies has downgraded BSE to 'Underperform' from 'Hold' and cut its price target by 16% to ₹2,940, citing what it calls a 'triple whammy' of regulatory pressures. The brokerage has trimmed its FY27-29 EPS estimates by 5-12% and warned of further downside if market-share gains stall. As reported by The Economic Times, Jefferies identified the Securities Transaction Tax hike, tighter RBI bank-guarantee norms raising collateral costs, and the new Closing Auction Session as key headwinds. The brokerage noted that prop traders account for 50-60% of the equity options notional turnover, with domestic prop traders likely accounting for half of the turnover. Jefferies expects the average daily turnover to recover from the second half of FY27, with stabilisation in CAS. We cut FY27-29e EPS by 5-12% due to slower ADTO growth expectations and higher clearing costs, analysts at Jefferies stated while downgrading the stock.
Global brokerage Nuvama Institutional Equities has independently downgraded the stock to 'Hold' from 'Buy' and slashed its price target to ₹3,240 from ₹4,090, representing a 21% downside from current market price levels. The brokerage has cut FY27 and FY28 EPS estimates by 6.3% and 15% respectively, with Nuvama noting that consensus estimates could also see a reset after BSE's second-quarter earnings. According to The Economic Times, Nuvama states that CAS has reset index option volumes to a new low, while the RBI's bank guarantee norms will begin biting from Q4FY27. The brokerage noted that options ADTO for NSE and BSE MTD in August 2026 was down 14% and 12% vs July 2026, with option ADTO down 20-23% for BSE/NSE in Week 2 of CAS vs Week 1. The revised target of ₹3,240 is below the Bloomberg consensus estimate of ₹4,014.18, suggesting potential upside of about 21% from current levels. Nuvama analyst Prithvish Uppal wrote that "With contract market share at ~50% and incremental levers exhausted, we see no near-term trigger."
The Closing Auction Session (CAS), introduced on August 3, is creating significant challenges for BSE with options turnover and volumes dropping substantially after the new system was implemented. According to The Economic Times, the new closing auction mechanism is "the biggest immediate trigger" as it is meant to improve closing price discovery and reduce manipulation. However, the rollout has changed the way traders behave on expiry day, with earlier predictable decay patterns now disrupted. Nuvama noted that CAS has introduced uncertainty in final settlement because the closing price is now discovered through an auction, which has weakened theta-harvesting strategies, reduced leverage for buyers and reduced seller interest because option decay has become less predictable. This particularly hurts BSE because its derivatives business is heavily dependent on expiry-day volumes, with BSE expiry-day contracts falling 33.2% compared with a 23.6% decline on non-expiry days. Jefferies also flagged BSE's dependence on Sensex weekly options, stating that BSE's market share gains have been led largely by expiry day, while gains outside T-0 and T-1 days have slowed.
Despite the downgrade pressure, BSE reported robust financial results for Q1FY27 with consolidated revenue rising 63.5% to ₹1,566 crore compared to ₹958 crore in the corresponding quarter of the previous year. According to Business Standard, on a consolidated basis, BSE's net profit increased 62.3% YoY to ₹873 crore in Q1 FY27. Investment income also rose sharply to ₹135 crore from ₹79 crore, while other income stood at ₹5 crore against ₹7 crore in the year-ago period. The company's Return on Equity (ROE) improved significantly to 37.41% in March 2026 from 9.58% in March 2022, demonstrating strong operational efficiency. However, the brokerage notes that if BSE's market share remains flat in FY28-29 compared with FY27, it sees a further 2-5% downside to earnings. Jefferies pointed out that consensus was factoring ₹27,000 crore of options average daily turnover in FY27 and around 20% growth in later years, but BSE's average daily turnover has been below ₹270 billion for the last three months.
