This Vanguard ETF Is Up 12% in 2026. Here's Whether Long-Term Investors Should Still Be Buying at These Levels.

Vanguard's S&P 500 ETF (VOO) has risen 12% year-to-date and hit an all-time high, but faces near-term challenges including elevated valuations at 21x forward earnings, heavy concentration in tech stocks, and AI market dependency. However, the S&P 500's historical 10% average annual return makes VOO suitable for long-term investors with a decade-plus time horizon, though short-term investors should consider alternatives like CDs or T-bills.
