Source: quarterly 13F filings, via EDGAR. A 13F reports positions by CUSIP alone; each CUSIP here has been confirmed against OpenFIGI rather than matched by name, because a name match would attribute one company's shareholders to another. Positions are as of quarter end and can be months old by the time they are filed, and 13F covers long equity positions only — not shorts, and not most debt. The summed value is what these filers reported, not the company's institutional ownership.
