What are the differences between ETFs and close-ended mutual funds?
Though Close-Ended Mutual Funds are listed on the exchange they have a limited number of shares and trade at substantial premiums or more often at discounts to the actual NAV of the scheme. Also, they lack the transparency, as one does not know the constitution and value of the underlying portfolio on a daily basis. In ETFs, the number of units issued are not limited and can be created / redeemed throughout the day. ETFs rely on market makers and arbitrageurs to maintain liquidity so as to keep the price in line with the actual NAV.
