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.

How is investor similarity calculated?

HoldLens uses Jaccard similarity on shared tickers: |A ∩ B| / |A ∪ B|. For each pair of investors, count tickers held by both, divide by tickers held by either. Range 0% (no overlap) to 100% (identical portfolio). Computed from latest SEC 13F-HR filings for Howard Marks and the 29 other tracked superinvestors.

Why does Howard Marks's portfolio overlap with these investors?
