% of Shares Out counts only shares held with sole investment discretion. Where two managers share discretion, Form 13F requires each to report the full position, so summing every filer exceeds 100% of shares outstanding for widely-held names.

Quarterly holdings from SEC Form 13F-HR structured data sets (filed within 45 days of quarter end); 5%+ ownership events from Schedule 13G/13D filings scanned daily via EDGAR. Each row links to the source filing. Est. Avg Cost is a rolling-average estimate — each quarter's added shares priced at that quarter's 13F value ÷ shares, split-adjusted, with history beginning 2024-Q2; positions with one quarter of history or a data-quality flag show “—”.
