HDFC Bank DHFC merger: After HDFC twins merger, a good number of equity mutual funds will have more than 10 per cent stock exposure in HDFC Bank shares. The equity mutual fund schemes include Invesco India Tax Plan, Bandhan Large Cap Fund, Tata Equity P/E Fund, Sundaram Large Cap Fund, etc. However, as per the SEBI rule, one mutual fund scheme can't have more than 10 per cent exposure in one stock. So, due to this HDFC twins merger, SEBI has a task to look at as overnight stake selling may lead to artificial downside in HDFC Bank share price.
