What this means
SPY and VTI share most of their portfolio weight in the same underlying stocks. OverlapCheck labels this "high holdings overlap" using house ranges of 70% or more, 30% to under 70%, and under 30%. These descriptive ranges are not industry standards or investment guidance. Holdings overlap does not measure correlation, volatility, geographic or factor exposure, fees, or suitability.
Overlap by weight sums the smaller of the two funds' weights for every stock they both hold. It answers "how much of my money is in the same stocks either way?" See methodology.
This comparison covers normalized equity positions represented in the dataset. Cash, derivatives, options, structured notes, and other non-equity assets are not included, so the result is not a complete comparison of every asset or risk in either fund.
