ETFs on the Rise

Mutual funds are still king of the investment world, but investor interest in exchange-traded funds (ETFs) has grown quickly over the last decade. At the end of 2017, more than $3.4 trillion in assets were invested among over 1,800 ETFs. This is equivalent to about 18% of the assets invested in mutual funds. In 2007, ETF assets were equivalent to only about 5% of mutual fund assets.1
