If I Could Invest $500 in Just 1 ETF in September, Here's What I'd Buy

A Motley Fool analyst recommends the Vanguard Total International Stock ETF (VXUS) as a single $500 investment choice for September 2026, citing concerns about S&P 500 valuations driven by AI stocks. VXUS has delivered 26% returns over the past year and 19.8% annualized returns over three years. Vanguard research forecasts international stocks may outperform U.S. stocks by 1.2-2.2% annually over the next 30 years.
