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.
Congress
No congressional trades in SI on record.
Members of Congress report trades within 45 days of the trade date, so these are never real-time. Amounts are disclosed as ranges; the net uses each range's midpoint (≈).
