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.
VOO did best over the period: $1,000 grew to $2,065 (+106.5%), compared with $2,052 (+105.2%) for SPY and $2,023 (+102.3%) for FXAIX. VOO also led across the reported shorter periods, including 1 year (+15.1%), YTD (+12.4%), 6 months (+7.0%), and 3 months (+3.1%). Its advantage likely reflects its lower 0.03% expense ratio versus SPY’s 0.09%; FXAIX’s expense ratio was not provided. SPY and VOO had nearly identical risk: 12.7% trailing-12-month volatility, with worst drawdowns of -18.8% and -18.7%, respectively. FXAIX was slightly less volatile at 12.6% but had the largest drawdown at -19.0%. The differences are small because the funds closely track the same S&P 500 exposure, but VOO’s persistent cost advantage mattered over this period.
