All three publicly traded trust banks (BNY Mellon, State Street, and Northern Trust) underperformed other categories of asset managers during 2017, and only State Street outperformed the S&P 500. While all three benefited from growth in Assets Under Custody and Administration (AUCA) and Assets Under Management (AUM) due to strong equity markets in 2017, the trust banks performed more in line with U.S. banks generally during 2017.
