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.
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; 7 additional owner(s) remain in Form 4 evidence.
Purchase breadth & concentration
Roles in the peak window: Director. Concentration uses priced qualifying P lines only and does not change the saved score.
SIGNAL HISTORY
Scores are archived only when the company qualifies for a published US buy-signal snapshot. Last qualifying purchase: 2026-08-14 · Phanstiel S. Louise.
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.
