GKOSGlaukos Corporation
What is the market doing?
No clear lean: rangebound and insiders net selling (often routine).
Choppy, but holding above its 200-day average. Price is +24% vs its 200-day average.
Insiders were net sellers over the 90 days ending Oct 9, 2026; selling is often routine (taxes, diversification).
Moderately shorted, settled Sep 30, 2026, about a week of normal trading to cover. Down 7.6% since the previous count, down from 7.7% of shares outstanding three months ago.

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.
