Method and sources
Source: SEC Form 13F data sets (bulk). Each row links to the holder’s own 13F-HR filing. Holder names exactly as filed; one group can file under several names and CIKs (for example two Vanguard entities), and they are listed separately, as filed.
% = the holder’s shares ÷ all shares reported in 13F filings for this company and quarter (calculated by Hollsteen). This is not a share of shares outstanding. Change = shares vs the same filer’s 13F for the prior quarter (Mar 31, 2026).
Erroneous filings and rows are handled by a fixed rule set (restatements replace originals; non-equity rows and implausible rows excluded): 9 erroneous filings excluded or replaced this quarter. No market values are shown.
SEC filings only. No price or market data.
