Under Armour Inc shareholders shouldn’t be too concerned about CEO Kevin Plank selling more than 2 million shares of Under Armour stock. According to Baird analyst Jonathan Komp, Plank has been selling for years and his timing hasn’t been particularly good.“In fact, we estimated that UA’s stock has returned an average of +5 percent during the 9 days following the historical sales since 2011 and that the stock has been positive over the 90-days post sale in about two-thirds of the occasions,” Komp explained.“Separately, we think UA is having a relatively good Back to School period,” he added.Source
