Why IPOs matter for insider data
A newly listed company has no insider history, which is why the first few months are worth watching. Officers and directors start filing Form 4 once the registration takes effect, so the first purchase by a founder or a new chief financial officer lands on a blank record instead of a pattern.
The lockup end is the other date to note. Insiders are usually barred from selling for 90 to 180 days after listing, so a wave of Form 4 sales right after the lockup ends says more about the calendar than about the business. Buying during a lockup is rarer, and more deliberate.
Price range and status come from the S-1 and its amendments, so both change as an offering moves from filed to priced. A missing range means the company has not published one yet.
