The Vanguard S&P 500 ETF (VOO) Beat the Vanguard Morningstar Total Stock Market ETF (VTI) for 4 Straight Years. Here's Why That's About to Change.

After outperforming for four years due to mega-cap growth stock concentration, the Vanguard S&P 500 ETF (VOO) is losing ground to the Vanguard Total Stock Market ETF (VTI) in 2026. VTI's exposure to cheaper small and mid-cap stocks, combined with its flexibility to quickly add new IPOs like SpaceX, makes it a better choice for broad market exposure despite both ETFs' identical 0.03% expense ratios.
