What is the market doing?
No clear lean: rangebound and insiders net selling (often routine).
Choppy, but holding above its 200-day average. Oversold (RSI 27). Price is +15% vs its 200-day average.
Insiders were net sellers over the 90 days ending Oct 8, 2026; selling is often routine (taxes, diversification).
Moderately shorted, settled Sep 15, 2026, about a week of normal trading to cover. Down 2.1% since the previous count, up from 4.3% of shares outstanding three months ago.
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.
