Swastika Investment: Recommends a ‘Subscribe’ rating, citing dominant market presence— holding nearly 93% share in cash markets and 99.8% in equity futures.
Religare Broking: Maintains a ‘Neutral’ stance, highlighting reliance on options transaction fees, regulatory exposure, and technology outage risks.
Paul Asset Management: Points out that at 42.9x FY26 earnings, valuation is reasonable compared to BSE’s 53x, but notes that future returns depend on diversifying away from pure options income into areas like GIFT City and data index solutions.
