Exchange-traded funds have exploded over the past several years and investors literally can't get enough.
In fact, respondents to a recent survey from Charles Schwab said the industry needs to grow even more, with 66 percent saying there's room for still more ETFs. The sentiment comes at a time when both the total amount of funds and the assets investors are plowing into them are increasing rapidly and investor appetite just seems to grow stronger.
"The industry's changing. There's innovation that's going to be needed," Michael Iachini, Schwab's managing director of ETF research, said in an interview. "We think more product means more competition and better pricing."
Indeed, it's pricing that has brought many people to ETFs and swelled assets under management globally to $2.6 trillion and domestically to $1.86 trillion, according to State Street, which is the second-largest issuer of the funds with $406 billion under management.
