<h1>Equity markets slip after heavy FII selling, H-1B fee and tariff worries trigger disclosure and surveillance concerns</h1> Equity benchmarks opened lower after sustained foreign institutional selling and concerns over a new US H-1B visa fee and tariffs dampened investor sentiment, with several large-cap and mid-cap stocks falling while other major firms gained. Market indices have declined over consecutive sessions and exchanges reported sizeable FII net sales. The developments raise regulatory and compliance considerations for market surveillance, disclosure obligations by listed issuers about material risks, potential cross-border regulatory interactions regarding immigration-related policy impacts on listed companies, and heightened monitoring by securities regulators for market integrity.
