Factset Research Systems Inc.
A financial data and analytics platform that delivers market data, research tools, and AI-powered technology to investment professionals around the world, serving buy-side investors, dealmakers, and wealth managers through subscriptions. It traces to 1978, when two colleagues at a Wall Street firm began delivering computer-based financial information directly to investors. The name comes from the "fact set," a four-page report one founder invented that packed a company's key numbers onto a single page.
Estimated from filings — the split-adjusted price range over the quarters each manager built the position. A range, not a fill price; 13F reports a quarter-end snapshot, not a trade date.
