In many ways, 2025 highlighted the key drivers of trading activity in retirement plans. During the first half of the year, trading surged as stocks slipped into negative territory. In fact, 36 of the 44 above-normal1 trading days occurred within the first four months, with investors shifting from equities to fixed income.
As markets rebounded in the second half of the year, trading activity eased. Bond funds represented half of all net inflows, while target date funds accounted for half of the net outflows. Still, target date funds remain the largest asset class at 31%, closely followed by large-cap U.S. equity at 30%.
