Shareholding limits in recognised stock exchanges restrict public ownership, resident holdings, and set capped foreign investment conditions. Regulation 17 mandates a minimum public holding in a recognised stock exchange and sets ceilings on individual and concerted holdings by residents and non-residents, while permitting specified institutional domestic and foreign entities to hold higher limited stakes; it further caps aggregate non-resident ownership subject to Central Government limits and prohibits clearing corporations from holding any interest in a recognised stock exchange.
