Why use a Form 4 tracker?

Form 4 filings are public, but reviewing them company by company is slow. insider screener brings the filings into one searchable feed and helps separate relevant activity from routine transactions.

SEC filings

Open and review individual filings

Find the activity that matters

Built around the workflows of investors who follow US insider activity — not raw regulatory feeds.

Screeners

Go beyond the latest filings

Use pre-built screeners to narrow the US market to the types of activity relevant to your research.

  • Top insider buys — companies with strong recent insider buying
  • Largest purchases — purchases ranked by transaction value
  • Cluster buys — several insiders buying the same company
  • Executive buys — purchases by senior executives
  • Buying after price declines — purchases following a fall in the share price

Understanding Form 4

What is Form 4?
Form 4 is used to report changes in the ownership of company securities by directors, officers and certain major shareholders.
When is Form 4 filed?
Most reportable transactions must be disclosed within two business days.
Does every Form 4 represent an open-market trade?
No. Filings can also include share awards, option exercises, gifts and other ownership changes. insider screener classifies transactions so that purchases and sales can be viewed separately.
What is Form 144?
Form 144 reports a proposed sale of restricted or control securities. It indicates an intention to sell, rather than confirming that the sale was completed.
Is insider buying legal?
Yes. Insiders can legally trade company shares, subject to securities laws and company trading policies. These disclosed transactions are different from illegal trading based on material non-public information.
Where does the data come from?
US transaction data is sourced from filings submitted to the Securities and Exchange Commission.
