PTGXProtagonist Therapeutics, Inc.
What is the market doing?
No clear lean: nothing decisive, though heavily shorted (+12% of shares).
Choppy, but holding above its 200-day average. Price is +31% 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.
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.
