ITOT vs VOO
iShares Core S&P Total U.S. Stock Market ETF 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 October 28, 2022 grew to $2,065, versus $2,018 for ITOT, a 106.5% gain compared with 101.8%. VOO also led across the 1-month, 3-month, 6-month, YTD, 1-year, and 3-year periods. The difference matters because VOO delivered higher returns with slightly lower risk: 12.7% volatility versus 13.0% for ITOT, and a less severe worst drawdown of -18.7% versus -19.4%. Both funds had the same 0.03% expense ratio and moved almost identically, with a 0.996 correlation. ITOT provides broader U.S. stock-market exposure, but that diversification did not improve results over this period; VOO’s S&P 500 exposure was the stronger performer.
