"Investors are not looking at products that are invested like individual stocks," he said. "People prefer the liquidity you get in an ETF versus actively managed funds."
Bonds, meanwhile, are becoming less popular. "Investors are looking at bonds and realizing they are not a risk free asset anymore," Fink said
Earlier Thursday, BlackRock, the world's largest money manager, reported fourth-quarter earnings of $3.96 a share, topping expectations of $3.73 a share.
Fink's Investment Outlook
"The U.S. will continue to be a great place to invest," Fink said. "It will be incredible energy and manufacturing story over the next few years." Fink also has a bullish outlook for Mexico calling it "an incredible growth story."
Fink also sees strength in U.S. banks. "The U.S. banking systems are in the best shape they have been in 5 years. I would not be shying away from investing in some of the best-run investment firms."
