Price Correlation
Methodology
What this report can and cannot establish
Known overlap: for each shared security, we add the smaller reported fund weight. Reported weights remain in their original scale.
Possible overlap: the upper bound adds only the smaller unreported portion. It is uncertainty, not an estimate that the missing positions actually match.
Prices: returns and risk use adjusted-close observations, so distributions and splits are reflected when supplied by the market-data source.
No recommendation: EigenDex does not assign a winner. Costs, tax treatment, liquidity and mandate should be verified with each issuer before acting.
