Fairfax Financial Holdings has boosted its position in Under Armour to nearly 42 million shares, representing approximately 22% of the company’s outstanding common stock. This move comes after a challenging year for the sportswear maker, during which its share price experienced an 18% gap lower in early August. Since late November, the stock has recovered more than 30%, driven in part by growing confidence from large institutional investors. Under Armour’s stock has closed higher in nine of the past ten trading sessions and today cleared its 200-day moving average, signaling a potential shift in long-term technical momentum.

Short interest in Under Armour remains high, with nearly 30% of the float sold short, implying it would take almost six trading days to cover all short positions at average daily volume. Such elevated levels raise the prospect of a short squeeze if bullish catalysts emerge. On the analyst front, three firms maintain a buy rating or better, while 22 assign hold or underperform ratings, leaving room for potential upward revisions. Options traders have taken notice: call volume has doubled the intraday average, with over 3,000 contracts traded today. The most active positions are in near-term January calls, followed by longer-dated January 2027 contracts with a strike well above current levels, reflecting varied bullish sentiment across time horizons.
