How to read the signal
- Start with the Form 4 transaction code, then separate voluntary trades from compensation mechanics.
- Compare buy volume against sell volume to determine whether capital is entering or leaving the stock.
- Weight executive rank, transaction size, active insider count, and remaining ownership before drawing conclusions.
- Use footnotes to identify 10b5-1 plans, tax withholding, gifts, trusts, or non-market transfers.
