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.
