FNILX vs VOO
Fidelity ZERO Large Cap Index Fund against Vanguard S&P 500 ETF: 4 years of returns, risk and today’s technical read, from Kavout’s own data.
VOO did better over the period: $1,000 invested on Oct 28, 2022 would be worth $2,065, versus $2,039 for FNILX, a difference of $26. VOO also led over three years (+83.6% versus +80.4%), one year (+15.1% versus +13.4%), and YTD (+12.4% versus +12.0%), while both returned +3.1% over three months. FNILX led in 27 of the last 48 months, but VOO’s stronger cumulative result indicates a modest long-term advantage. Risk was similar: VOO had slightly lower 12-month volatility (12.7% versus 12.9%) and a less severe worst drawdown (-18.7% versus -19.1%). VOO’s 0.03% expense ratio and $1,671B in assets add cost and scale advantages; FNILX’s principal advantage was its slightly more frequent monthly outperformance.
