Does following Under Armour, Inc.’s insiders pay?
From February 16, 2010 to August 12, 2026, 41 insiders reported 17 open-market purchases and 128 sales not made under a pre-set plan in Under Armour, Inc. Twelve months after each purchase was reported, the shares were −6.4% against the S&P 500 on average (median −21.1%), over 10 purchases with a full year of prices; 30% beat the index. After sales, the shares moved +2.1% against the index over 12 months (a negative figure means selling was the right call). That rests on fewer than 20 purchases, too few to read much into. Buying each purchase the day after it was reported, an equal amount each, held 12 months or until that insider reported a sale, would have turned $10,000 on August 17, 2015 into $3,838 by November 2, 2026, −8.2% a year. It held shares 42% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $17,266 (+5.0% a year), and held throughout $43,193 (+14.0%).
