Funds will continue to flow from actively-managed funds to passive ones in 2017, said Gary Meltzer, U.S. Asset & Wealth Management Sector Leader at PwC. He added that the trend of money moving from mutual funds to exchange-traded funds will extend into the coming year, too. Asset managers that can differentiate themselves through better performance or technology will be the ones that hold onto their assets, or even add to them, according to Meltzer. The big winners among asset managers in 2017 will be those with size and scale, in his view.
