The U.S. exchange traded fund universe has almost 2,000 different options available with about $2.8 trillion in assets under management, but the industry continues to expand its offerings and grow assets.

ETF Trends publisher Tom Lydon spoke with Dave Nadig, CEO of ETF.com, at the Inside ETFs conference that ran Jan. 22-25, 2017 to talk about developments in the ETFs that could continue to propel the industry.

“The active passive debate just seems to never get old, right,” Nadig said. “I mean everybody’s talking about smart beta. They’re talking about new entrants from the active space. We’ve got folks like Davis here, you know. launching brand-new funds – traditional stock-picking active showing up in spades. I think that’s a big topic of conversation; I think we’re going to see a lot more of it this year.”
