Insider conviction−$24.9M (90 days to Oct 22, 2026)SEC EDGAR · Oct 22, 2026

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

Short interest8.4% of sharesFINRA · Sep 30, 2026

Heavily shorted, settled Sep 30, 2026, about a week of normal trading to cover. Up 17% since the previous count, up from 5.4% of shares outstanding three months ago.

Where this answer is blind. Insider selling is often routine (taxes, diversification); only cluster buying is a strong tell.
