US Fund Flows: Mutual Funds and ETFs Bounce Back in May

Long-term US mutual funds and exchange-traded funds gathered $58 billion in May 2024 after suffering outflows last month.


Key Takeaways

  • Taxable-bond funds pushed their 2024 inflows over $200 billion with a $36 billion haul in May.

  • Large-growth equity funds enjoyed their strongest month of inflows since March 2022, taking in nearly $5 billion.

  • Alternative ETFs reeled in more than $3 billion behind more inflows into bitcoin and defined-outcome ETFs.

After a sudden dip in April, US funds took in $58 billion in May, marking a resumption of their prior trend. Demand was broad based, as seven of the 10 category groups enjoyed inflows. Passively managed offerings took in $73 billion, while actively managed strategies saw roughly $15 billion leave.

Taxable-Bond Funds Keep Rolling

Taxable-bond funds are on a roll. They raked in $430 billion from January 2023 through May 2024, scoring inflows in all but one month over that span. Meanwhile, all other US funds collectively bled $133 billion. How bond-fund investors have fared depends largely on when they jumped in. The Morningstar US Core Bond Index climbed 5.3% in 2023 but slid 1.5% in 2024 through May.

Alternatives: Another Avenue for ETF Growth

Exchange-traded funds expanded their share of the liquid alternatives market from 6% to 47% over the five years ended May 2024. Two main developments explain the rise. The first was the advent of defined-outcome, or “buffer” ETFs, whose downside protection vaulted them into the mainstream after the early-2020 pandemic-fueled drawdown. The second was the early-2024 launch of bitcoin ETFs—an immediate sensation that drove alternative ETFs to new heights.

Large-Growth Funds Shine in May

US equity funds are off to a slow start to the year, with just $18 billion of cumulative inflows. Index funds typically dominate the category group, and May was no exception: Passive funds took in $44 billion, while active funds shed more than $17 billion. Large-growth funds notably enjoyed their strongest month since March 2022, taking in $4.7 billion. The Invesco QQQ and Invesco Nasdaq 100 ETFs were the category’s top flow winners in May; both feature huge stakes in the largest tech companies.
