FYI: There are only 225 actively managed funds in a universe of more than 2,100 U.S.-listed ETFs. Not only are more than 80 of those active ETFs classified as fixed-income products, all but two of the top 10 actively managed fixed-income ETFs in terms of assets cover the fixed-income space. Active management is a popular approach when it comes to fixed income, and much of that may have to do with a record of superior performance.
