Insider Trading Activity (Form 4 Filings)

An insider trade occurs when an individual that has non-public information about a company buys or sells shares of that company’s stock. Examples of insiders include a company’s executive officers (CEO, CFO, COO), its board of directors, and its major shareholders. Insiders are required to submit their trading activity to the SEC through Form 4 filings.

What these mean— the action is the SEC’s own Form 4 transaction code. Only a buy or a sell is an open-market trade; the rest are transfers, awards and exercises, which is why they carry no price.
  • Award (A) — Grant or award from the company, not a purchase
  • Tax withheld (F) — Shares withheld to pay tax or an exercise price
  • Option exercise (M) — Exercise or conversion of an exempt derivative
