What this means
RSP and SPY share a material portion of their portfolio weight in the same underlying stocks. OverlapCheck labels this "moderate 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.

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.
