109 Form 4 transaction lines observed in the same window
2 sales · 105 option, withholding, award, gift or other lines
WHY NO ACTIVE SIGNAL?
Score anatomy
No score is calculated because there is no qualifying purchase in the active window. Unavailable inputs are not treated as zero or as a bearish signal.
Why is there no score?
- No qualifying open-market purchase supplies cluster, size, role, recency or conviction inputs.
- Sales and other Form 4 activity remain visible as context and do not create a negative score.
Sales and other Form 4 activity are shown separately and do not create a negative buy signal. Absence of buying is not scored as bearish.
Purchase breadth & concentration
Roles in the peak window: VP, CAO & Assistant Treasurer. Concentration uses priced qualifying P lines only and does not change the saved score.
Insider activity timeline
Owner lanes show the latest 180 days. Symbol shape identifies the transaction type; sales remain context only.
Showing the six most active owners; 5 additional owner(s) remain in Form 4 evidence.
SIGNAL HISTORY

Recent Form 4 activity
P is an open-market or private purchase. S is a sale. M, F, A and G usually describe exercises, tax withholding, awards and gifts. These categories remain visually separate.
