VSMPX vs VTI
Vanguard Total Stock Mkt Idx Instl Pls against Vanguard Morningstar Total Stock Market ETF: 4 years of returns, risk and today’s technical read, from Kavout’s own data.
VSMPX did slightly better over the period, with $1,000 growing to $2,018 (+101.8%) versus $2,017 (+101.7%) for VTI. The difference was negligible: both funds had identical returns over the 1-, 3-, and 6-month periods and YTD, while VSMPX led by 0.1 percentage point over one and three years. Their daily moves were nearly identical, with 0.998 correlation overall and 0.999 over the last 12 months; VSMPX moved 0.99% for each 1% move in VTI. Risk was also almost the same: VSMPX had 13.0% volatility and a -19.4% maximum drawdown, compared with VTI’s 12.9% volatility and -19.3% drawdown. VTI’s 0.03% expense ratio and ETF structure may matter more for implementation, but performance differences were immaterial.
