Insiders were net sellers over the 90 days ending Oct 22, 2026; selling is often routine (taxes, diversification).

Short interest1.5% of sharesFINRA · Sep 30, 2026

Lightly shorted, settled Sep 30, 2026, a few days of normal trading to cover. Up 4.3% since the previous count, down from 1.6% of shares outstanding three months ago.
