FXAIX vs SPY
Fidelity 500 Index Fund against State Street SPDR S&P 500 ETF: 4 years of returns, risk and today’s technical read, from Kavout’s own data.
SPY did better over the period: $1,000 invested on October 28, 2022 would be worth $2,052 versus $2,023 in FXAIX, a 105.2% gain versus 102.3%. SPY also led over one year and three years, while its recent returns were generally higher. The difference was modest, reflecting their highly similar S&P 500 exposure: daily-move correlation was 0.981, and the typical monthly performance gap was only 0.05 percentage points. Risk was nearly identical. Twelve-month volatility was 12.7% for SPY versus 12.6% for FXAIX, while worst drawdown was -18.8% versus -19.0%, respectively. SPY’s 0.09% expense ratio and ETF structure may matter for investors prioritizing tradability and transparency; FXAIX’s slightly lower observed volatility and comparable results may appeal to investors focused on mutual-fund investing.
