Officers, directors and 10% owners file SEC Form 4 within two business days. Unplanned: the insider chose to trade now, the trades worth attention; their dollars make the net above. 10b5-1 plan: scheduled in advance, kept for the record. Tax: shares withheld on vesting stock, not a market trade. Awards, option exercises and gifts are left out. Source: SEC EDGAR, collected daily for the stocks discussed on Reddit.
