Why OpenStocks
A single source of truth. Manager portfolios, insider trades, and Congress disclosures — one schema, one URL per entity, every signal cross-linked.
Composite signals. When institutions, insiders and Congress all agree, you'll see it on /smart-money-signals.
Open & inspectable. Every page links straight back to the original 13F, Form 4, or PTR PDF on EDGAR or the House Clerk.
Every quarter, the SEC publishes 13F filings disclosing the U.S. equity holdings of institutional investors managing $100M+ in assets. OpenStocks decodes those filings into clean, comparable super-investor portfolios — from Berkshire Hathaway to Pershing Square — with quarter-over-quarter position deltas, sector exposure, and a permanent URL per investor.
We also normalize every U.S. corporate insider trading disclosure filed on Form 4 (officers, directors, and 10%+ owners) into a unified timeline, with net-flow rankings by ticker, by insider person, and by company.
On the legislative side, every U.S. House congress stock trade disclosed under the STOCK Act is parsed straight from the official PTR PDFs and mapped to individual members and committees.
Browse holdings by ETF, sector, or industry. Read the daily market digest to see the most consequential disclosures from the prior trading day, and check smart money signals for the rare moments when institutional, insider, and Congress flow all converge on the same name.
