CERSCerus Corporation
What is the market doing?
No clear lean: rangebound and heavily shorted.
Rangebound, no clear trend. Price is −5% vs its 200-day average.
Heavily shorted, settled Sep 30, 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.
