INBXInhibrx Biosciences, Inc.
What is the market doing?
No clear lean: insiders cluster-buying, but a crowded short (+22% of shares).
Choppy, but holding above its 200-day average. Oversold (RSI 24). Price is +5% vs its 200-day average.
Multiple insiders bought with their own money, the strongest form of the signal (the 90 days ending Oct 8, 2026).
A crowded short, settled Sep 15, 2026, more than a week of normal trading to cover, a crowded exit.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. Insider selling is often routine (taxes, diversification); only cluster buying is a strong tell.
