Muni bond fund investors earned half of what their funds returned.
Morningstar's new study covers the ten years through December 2025.
Municipal bond funds returned 2.2% a year. The average dollar
invested in them earned 1.1%.
Stock investors, meanwhile, were fine — 12.8% against their funds'
13.3%.
The numbers:
→ U.S. stock funds: 12.8% investor vs. 13.3% fund
→ All funds: 8.7% vs. 9.9%
→ Muni bond funds: 1.1% vs. 2.2%
Two caveats worth stating. Munis returned little in absolute terms
over this stretch, so a 1.1-point shortfall is enormous in relative
terms and modest in dollars. And a peer-reviewed paper in this year's
Financial Analysts Journal argues Morningstar's methodology overstates
the size of these gaps. Not every dollar of it is a mistake —
rebalancing and spending move money too.
Still, the pattern is worth sitting with. The sleeve most investors
think of as the safe, boring one is where the timing damage showed up.
Bonds bought as a shock absorber only absorb shocks if you hold them
through the shock.

the bonds?
