In keeping with information reviews, analysts at Jefferies have reduce FY27-29E EPS estimates by 5-12%. Jefferies, reviews mentioned, notes that BSE trades at 44x 1-year ahead EPS.
BSE’s revenues from home proprietary merchants, which account for round 50% of notional turnover, may very well be in danger on account of headwinds from the STT hike, RBI financial institution assure (BG) norms, and the Closing Public sale Session (CAS).
Notably, BSE’s choices ADTO MTD in August 2026 is down 12% vs July 2026. Whereas consensus expects SENSEX to realize additional market share, BSE’s expiry-day market share is much like NSE, whereas market share good points exterior T-0/T-1 days have slowed.

Particulars to know
Jefferies’ concern is that CAS is one other headwind to BSE’s exceptionally excessive volume-growth assumptions, reasonably than a menace to BSE’s enterprise itself. CAS might change end-of-day buying and selling behaviour and probably cut back or reshape exercise from proprietary and high-frequency merchants.
CAS, or Closing Public sale Session, modifications how buying and selling occurs close to the market shut. As a substitute of steady buying and selling by way of the ultimate quarter-hour, eligible shares transfer into an public sale mechanism, which might alter end-of-day buying and selling behaviour and execution methods. CAS can negatively impression BSE primarily by way of buying and selling volumes and, subsequently, transaction-linked income.
The necessary level is that CAS itself isn’t essentially dangerous for the market—it’s a structural change meant to enhance closing-price discovery.
In the meantime, the STT hike will increase the price of derivatives buying and selling, whereas tighter RBI bank-guarantee norms improve funding/collateral necessities for prop merchants, making some buying and selling methods much less worthwhile. Jefferies has estimated that the RBI norms might have an effect on round 10–12% of choices turnover, with a possible round 10% earnings impression for BSE.
The important thing concern, subsequently, is the compounding impact of those three components: larger buying and selling prices from STT, larger funding necessities from RBI norms, and altering buying and selling behaviour on account of CAS might collectively gradual BSE’s choices turnover progress.
This might put strain on revenues and earnings.
