Questions

What the page counts, where the filings come from and how current it is.

What counts as an insider trade on this page?

A purchase or sale of a company’s own stock, on the open market or in a private sale (Form 4 codes P and S), reported on SEC Form 4 by one of its officers, directors or holders of more than 10% of its shares. Stock awards, shares withheld for tax, option exercises, gifts and trades in options, warrants or preferred stock are filed on the same form and are not counted here. Each company’s page lists them.

What is a 10b5-1 plan?

A trading plan set up in advance under SEC Rule 10b5-1, which then buys or sells on its own schedule or formula. A sale or a purchase is marked 10b5-1 here only when its Form 4 says it was made under such a plan. Of the 656 sales filed from Oct 7 to Nov 5, 2026, 449 say so, as do 12 of the 54 purchases.

How current is this page?

It is rebuilt every night from the Form 4 filings GetSignal holds for the 1,630 companies it covers, and this build covers filings dated Oct 7 to Nov 5, 2026. A Form 4 is due within two business days of the trade, so the newest trades reach the page a day or two later. The GetSignal app shows each filing as it comes in.

Where can I see one company’s filings?

On its company page. A ticker or company name here opens it, and an insider’s name opens its insider table, which lists the company’s 20 newest open-market filings with the shares, the price, the days each took to file and a link to the original on SEC EDGAR. A holder with its own page on GetSignal, such as a fund manager, opens that page instead. Each filing date on this page opens its Form 4 on EDGAR.
