Method
Jaccard similarity = |A ∩ B| / |A ∪ B| where A and B are the sets of tickers each investor holds in their most recent 13F filing.
A score of 100% means both investors hold exactly the same tickers. A score of 0% means no overlap. In practice, tracked superinvestors rarely exceed 40% — they pick unique spots even within similar philosophies.
Source data: SEC EDGAR 13F-HR filings, latest quarter available per investor. v1 uses unweighted Jaccard (set membership). v2 will add position-weighted similarity for a finer-grained score.
