BSE Shares Drop on Proposed SEBI F&O Norms

share price came under selling pressure following regulatory signals from SEBI proposing changes to the equity derivatives ecosystem. The primary catalyst behind the stock price decline stems from SEBI’s proposal to lengthen the maturity period of derivative contracts and shift market activity away from ultra-short-term weekly options. Derivatives serve as a core revenue engine for BSE, with a major portion of transaction fee income driven by high-frequency weekly contract trading. The regulator’s intent is to curb speculative trading behavior, manage retail trading risks, and enhance systemic stability. However, investors are concerned that shifting focus to longer-tenure monthly contracts will reduce overall trading turnover and entries, impacting exchange transaction charges and valuation multiples. Institutional investors reduced exposure, and brokerages turned cautious over potential regulatory risks, even as BSE reported strong revenue and net profit growth.
