BSXBoston Scientific
What is the market doing?
No clear lean: nothing decisive, though insiders cluster-buying.
Rangebound, no clear trend. Price is −22% vs its 200-day average.
Multiple insiders bought with their own money, the strongest form of the signal (the 90 days ending Oct 22, 2026).
Lightly shorted, settled Sep 30, 2026, a few days of normal trading to cover. Down 11% since the previous count, up from 1.9% 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.
