BSE Share Price Slumps: Jefferies And Nuvama Cut Target Price Amid New Rules

The shares of BSE, one of India's premier stock exchanges, have faced a significant downward trend for the second consecutive day. 5 percent. This slump isn't merely a result of general market volatility but is primarily driven by recent reports from major global brokerage firms such as Nuvama and Jefferies. These analysts have Importantly reduced both the rating and the target price for the BSE stock, citing various regulatory and operational challenges that could impact the exchange's profitability in the coming years.

Brokerage Firms Slash Ratings and Targets

The pressure on BSE shares intensified after the global brokerage firm Jefferies placed the stock in the underperform category, while jefferies has reduced the target price of the stock by 16 percent. Following this, Nuvama Institutional Equities also adopted a cautious stance. Nuvama downgraded the BSE stock rating from Buy to Hold. Along with this downgrade, they implemented a massive 21 percent cut in the target price, setting it at 3,240 rupees. The brokerages believe that the exchange's earnings will be directly affected in the upcoming years. 3 percent and 15 percent, respectively.

Impact of the Closing Auction Session

A major factor behind this shift in sentiment is the introduction of the Closing Auction Session (CAS). Previously, in option trading, there was a predictable pattern of premium decay as the expiry approached. This allowed short-term traders to easily formulate their strategies, while however, the arrival of the new closing session has Importantly increased uncertainty regarding the final settlement price. It has now become difficult to accurately estimate how the premium will decay. According to Nuvama's report, this uncertainty has dampened trader enthusiasm, while 2 percent. This has had a direct impact on BSE's average daily premium turnover, which has fallen to 18,100 crore rupees, its lowest level since January 2025.3 percent.

Stricter RBI Norms and Market Challenges

Beyond the new trading rules, the tightening of bank guarantee norms by the Reserve Bank of India (RBI) has emerged as a new challenge for BSE. These stricter regulations mean that intermediaries will now require more capital, while this is expected to adversely affect high-frequency trading strategies, which are major contributors to contract volumes. Jefferies highlighted that approximately half of BSE's total turnover comes from domestic proprietary traders. So, the combination of increased Security Transaction Tax (STT), the new RBI rules, and the changes in the auction session are directly hurting the exchange's earnings, while in the month of August so far, the average daily turnover of BSE's option trading has already fallen by 12 percent.
