According to Eric Balchunas, American Eagle Outfitters' stock experienced significant gains following its marketing campaign featuring actress Sydney Sweeney. The stock's performance outpaced traditional assets such as silver, gold, and even high-growth sectors like junior uranium miners and QQQ. This highlights the potential impact of celebrity endorsements on stock market performance.
