What is the market doing?
No clear lean: in an uptrend, but heavily shorted (+10% of shares).
In an uptrend, above its rising 50- and 200-day averages. Price is +22% vs its 200-day average.
Insiders were net sellers over the 90 days ending Oct 8, 2026; selling is often routine (taxes, diversification).
Heavily shorted, settled Sep 15, 2026, more than a week of normal trading to cover, a crowded exit.
Where this answer is blind. Insider selling is often routine (taxes, diversification); only cluster buying is a strong tell.
