Vanguard's VOO and State Street's SPY both closely track the S&P 500 and show nearly identical performance and risk profiles—each posted a 12.3% one‑year total return, beta of 1.00, similar sector weights (technology ~36%, financials ~13%, consumer cyclical ~11%), five‑year growth of $1,000 to about $1,823 and five‑year max drawdowns near -24.5% to -25.5%. The primary distinctions are structural: VOO charges a lower expense ratio (0.03% vs. SPY's 0.09%) and manages roughly $1.5 trillion versus SPY's $683.1 billion, so VOO is the fee‑efficient pick for long‑term holders while SPY offers scale and entrenched liquidity—otherwise there are no material tracking or portfolio differences.
Both Vanguard S&P 500 ETF (VOO) and SPDR S&P 500 ETF Trust (SPY) track the S&P 500 with effectively identical short‑ and medium‑term results: each posted a 12.3% one‑year total return, a beta of 1.00, a 1.1% dividend yield, and five‑year growth of $1,000 to about $1,823. Five‑year max drawdowns are comparable at roughly -24.5% (SPY) and -25.5% (VOO), and holdings counts are similar (VOO 505, SPY 503) with sector weights concentrated in technology (~36%), financials (~13%) and consumer cyclical (~11%). The clearest structural difference is cost and scale: VOO charges a 0.03% expense ratio versus SPY's 0.09%, while AUM figures in the article list VOO at $1.5 trillion and SPY at $683.1 billion; the fee gap favors VOO for long‑term compounding, but the piece stresses both funds have ample liquidity and negligible tracking differences. Portfolio composition shows concentration in mega‑cap tech (VOO top positions include NVIDIA 3.17%, Apple 0.86%, Microsoft 1.61%; SPY lists Netflix 3.88% among top holdings), which explains the correlated drawdown behavior. Because neither fund uses overlays or unique indexing rules, selection is primarily a function of fee sensitivity and incidental operational preferences rather than performance expectations; investors should therefore weigh the modest fee advantage of VOO against any personal trading or structural reasons to prefer SPY and monitor sector concentration and drawdown metrics when sizing positions.
