Bracing for big revenue hit after new F&O rules: Zerodha's Kamath

Zerodha CEO Nithin Kamath said the firm is "bracing for big revenue hit" later this year after SEBI's new rules on futures and options (F&O) are implemented. "We are already seeing revenue and profit plateau," he said in a blog post. SEBI is set to make several changes to F&O rules, including hiking securities transaction tax and raising contract size.
