What is the market doing?

Choppy, but holding above its 200-day average. Oversold (RSI 27). Price is +3% vs its 200-day average.
Heavily shorted, settled Sep 15, 2026, about a week of normal trading to cover. Up 7.6% since the previous count, down from 17.3% 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.
