Vanguard Total International Stock ETF VXUS

VXUS is the cheapest core international holding, with a 0.07% expense ratio covering over 7,600 non-US stocks from developed and emerging markets. This cost outperforms #2's typical target-date blend by 50%. With US stocks trading at P/E ratios 30–50% above equivalent European and Asian firms, VXUS positions investors for secular mean reversion. A 60/40 VTI-to-VXUS split mirrors global cap weights, offering true world ownership.
