There has been a 26-fold rise in assets under management (AUM) of exchange-traded funds (ETFs) in a little over five years to more than Rs 2 lakh crore now. The main reasons are government support for these schemes, rising popularity among investors, and acceptance by fund houses to launch equity and debt-based ETFs with lower management costs.Of the total, ETFs on the NSE’s Nifty index have a 49% market share, accounting for a little over Rs 1 lakh crore, data from MF industry body Amfi showed. And gold ETFs managed assets worth an additional Rs 13,500 crore. According to NSE MD & CEO Vikram Limaye, the exchange was working actively with the MF industry “for creating investor awareness and promotion of ETFs through various channels of communication in India”.
