What the record says
Description, identity and filings, each with its source.
Every block cites its source. The colour of a finding marks its category — which document, who filed it — not how much it matters.

Sale intention announced
On Oct 1, Thiel Frederick G filed notice of intent to sell up to $309K. It is filed under a scheduled plan (10b5-1), arranged in advance.
A notice is not a sale: it may not go ahead, may happen in part, or at a different price.
After the notice, they sold $309K on Oct 1, per their Form 4. That is 100% of the shares announced so far, and the window is still open.

This profile for every company we cover: closing prices with the record's facts on the curve, the SEC file in plain language, insider trades included, and links to its sector and exchange.
- Pro
What matters today, with its reason, is free with an account. Pro adds, in the profile, each company's notices and their explanation and the analysis of its insiders; in Radar, all the lenses, which notice each candidate carries, filters by notice type and «no dilution», and the cycle cohort filter; and in Watchlist, more companies and notice changes with their reason.
- Pro+
Adds the Lab: test a hypothesis on comparable cohorts before reusing it; and bring your lenses to Radar.
Are the prices real time?
No. It is one close per session, from the provider and with the date shown on the profile; it does not update during the trading day.
Which SEC documents appear here?
Those filed with the SEC by the company, its insiders and its major shareholders, within our coverage: periodic reports (10-K, 10-Q, 20-F), material events (8-K), proposed sale notices (Form 144), insider transactions (Form 4) and stakes above 5% (13D/13G). Each links to the original on EDGAR.
Why does a European company show no SEC records?
It depends on the company: some European issuers file a 20-F or 6-K with the SEC and others don't. The profile shows whatever is on record; when there is nothing, it says so rather than guessing why. Europe does not yet have a common filing archive like EDGAR in the United States. The EU will open its own, ESAP, in July 2027 (managers' transactions arrive in January 2028), and we plan to add it once it is available.
