VFIAX vs VTSAX
Vanguard 500 Index Fd Admiral Shs against Vanguard Total Stock Market Index Fund: 4 years of returns, risk and today’s technical read, from Kavout’s own data.
VFIAX did better over the period: $1,000 invested on October 28, 2022 would be worth $2,063 versus $2,016 for VTSAX, a 4.7 percentage-point advantage in cumulative return. VFIAX also led over the latest 1-, 3-, and 6-month periods, YTD, 1 year, and 3 years. The difference was modest because the funds were highly correlated, with daily-move correlation of 0.997; VFIAX moved 0.97% for each 1% move in VTSAX. VFIAX also had slightly lower risk: 12.8% versus 13.0% volatility over the last 12 months, and a less severe worst drawdown of -18.8% versus -19.4%. VFIAX therefore delivered the better combination of return and measured risk, while VTSAX’s broader market exposure did not overcome VFIAX’s stronger performance during this period.
