Head-to-head over the 11-year window both funds have in common (2015-07-27 → 2026-07-24): VOO (Vanguard S&P 500 ETF) vs SPY (SPDR S&P 500 ETF) — total return with dividends reinvested, both starting at $10,000 on the same date.
On risk-adjusted return, VOO came out ahead of SPY —
but the gap is only half the story. Drawdown and yield often matter more.
