Overlap = Σ min(weight A, weight B) across shared positions, computed only from the mapped positions of both managers.

13F filings cover long US equity positions only — no shorts, bonds or cash. “% of portfolio” refers to the manager’s reported 13F portfolio, not the entire fund. All facts come from public SEC filings with a link to the original document; this is not investment advice.
