Indexes a fixed 60% US total stock market / 40% US total bond market allocation.

The 60/40 portfolio gets pronounced dead every few years — most loudly in 2022, when both sides fell together — and then goes back to quietly doing its job. VBIAX is the purest implementation available: 60% total US stock index, 40% total US bond index, automatically rebalanced, 0.07%, no glide path, no manager opinions, no international wrinkle.

It's an underrated answer for money that needs to be sensible rather than optimized — an inheritance you don't want to actively manage, a conservative IRA, the equity-lite years before retirement. The main critique is the absence of international stocks, which makes it a deliberate home-country bet. Compare it with Wellington (VWELX) if you're curious what an active manager adds to roughly this allocation for an extra 19 basis points; the answer over most periods has been 'not much, reliably.'
