Overlap matrix

Shared top-10 positions · darker = more overlap

Every cell counts how many tickers two managers share in their top-10 holdings. Click any cell to see the full side-by-side comparison. Darker = more consensus. Dataroma has nothing like this — it's a raw holding count per manager and you're left to eyeball overlaps yourself.
