For years, active fund managers watched money walk out the door. Passive index funds were cheaper, simpler, and increasingly hard to argue against. But a growing number of active managers have found a surprisingly effective countermove: just change the wrapper.
The mutual fund-to-ETF conversion trend has accelerated dramatically, with over 200 funds making the switch since 2021. Those converted funds collectively held more than $260 billion in assets at the time of conversion, and the results have been striking. Funds that were bleeding an average of $150 million in net outflows over two years before conversion flipped to average inflows of roughly $500 million over the same period after becoming ETFs.
The numbers behind the ETF advantage
The scale of the reversal is hard to overstate. Approximately 71% of post-conversion ETFs have reported positive net flows, pulling in around $120 billion in total inflows against just $20 billion in outflows. The median inflow per converted fund sits at $125 million, with only 29% of funds continuing to face outflows after the switch.
Among firms that converted four or more funds, 12 out of 16 saw significant aggregate inflows post-conversion. Dimensional Fund Advisors and JPMorgan Asset Management have been among the most notable beneficiaries of this trend.
