'There's Room for Both Passive and Active in a Portfolio'

Todd Rosenbluth, head of ETF and mutual fund research at CFRA, is bullish on nontransparent active ETFs, he said at the 2020 Inside ETFs conference.

Rosenbluth said that there is a lot of investor interest in active management, and he expects firms like T. Rowe Price, Fidelity and American Century to all come out with nontransparent active ETFs in the coming months.

"They're all going to [be] coming out with ETFs that are like their mutual funds in 2020 and we think there is going to be investor interest, but there's a lot of skepticism in the industry," he said. "A lot of people love passive investing here ... but there's room for both active and passive within a portfolio."
