Methodology and caveats
QuantLink fetches this holder profile from the verified FastAPI 13F holder endpoint and renders a limited public teaser from the returned portfolio fields. We sort holdings by returned portfolio weight and do not fabricate missing issuers, market values, shares, weights, or performance.
A Form 13F is a quarterly snapshot that institutional investment managers generally file about 45 days after quarter-end. The data can lag the manager's current portfolio.
13F filings cover US-listed long equity positions only. They do not show shorts, cash, bonds, many foreign securities, private investments, derivatives outside required reporting, or smaller positions below reporting thresholds.
Position changes can reflect buys, sells, corporate actions, price movement, portfolio rebalancing, manager reporting changes, or security identifier changes between quarterly filings.
