WTMWhite Mountains Insurance Group, Ltd.
What is the market doing?
No clear lean: rangebound and moderately shorted.
Choppy, but holding above its 200-day average. Overbought (RSI 88). Price is +4% vs its 200-day average.
Moderately shorted, settled Sep 30, 2026, more than a week of normal trading to cover, a crowded exit.
Where this answer is blind. Insider selling is often routine (taxes, diversification); only cluster buying is a strong tell.
