Q&A

Open-market purchases of $100,000 or more by officers, directors and ten percent owners at NYSE- and Nasdaq-listed companies, taken from their SEC Form 4 filings.

Pre-scheduled 10b5-1 plan purchases, option exercises and awards, blank-cheque and SPAC issuers, companies below $300m in market capitalisation, recently listed companies, and anything under the threshold. These filters are the reason the list is short: most Form 4 activity is not an open-market purchase at all.

Yes. A director who buys through an entity they control has the same reporting duty and the same information, so it is included and labelled as an indirect holding. Most services do not make that distinction visible.

SEC Form 4 filings, read directly from EDGAR within minutes of publication. Closing and opening prices come from an end-of-day market data provider and are cross-checked.

The Uber filing on 10 September was accepted by the SEC at 12:40:37 ET and the alert went out at 12:43:16 ET — two minutes and thirty-nine seconds later.

Both are filings where the purchase and the filing fall on the same day. Same-session means the filing arrived while the market was open, so the alert carries a live price. Same-day means it arrived after the close, so the alert goes out that evening and the tracked entry price is the next morning's opening auction.

Two or more different insiders at the same company filing within five trading days of each other. One alert goes out when the second one files; if more join, the count on the dashboard grows but no second alert is sent.

Because most Form 4s report a purchase from an earlier day, sometimes days earlier. Those go to the dashboard and the daily email but not to an alert, since the price has already moved.

Roughly ten to fifteen a week at the current rate. That is an approximation, not a promise.

Enable them per device from the dashboard or the Account page. On an iPhone the site must first be added to the home screen and opened from that icon, because Safari only allows it there. Email alerts need no setup.

Yes. The daily email and the per-filing alerts are separate switches on the Account page.

Half an hour after the SEC filing window shuts: 22:30 in New York, 04:30 in Amsterdam. It contains everything filed that session.

Each alert is tracked from the price a subscriber could actually have paid, on settled closing prices only, never sold. The Portfolios page has the full method.

Because the members often buy days apart at prices that differ by several percent, so any single entry price for the group would be arbitrary. The cluster is a signal, not a portfolio.

No. Anything with NYSE and Nasdaq access works.

$20 a month or $200 a year, charged in USD, taxes included where applicable. Fourteen days free, and cancelling before day fourteen costs nothing. Cancel any time through the Stripe portal from the Account page.

No. It is an information service reporting public filings. It makes no recommendation and nothing on the site should be read as one.
