Wing sales are harder to predict than you might think. Buffalo Wild Wings' (NASDAQ:BWLD) stock is up more than 10% since it booked third-quarter earnings results, and shares are now approaching double what they were at the beginning of the year. Yes, analysts were surprised by Buffalo Wild Wings' reported profit and revenue growth last quarter. But that's only part of the story.
In the video below, Fool contributor Demitrios Kalogerpoulos argues that three deeper factors are helping to lift the wing-slinger's results beyond expectations right now: spiking traffic at existing locations, plunging costs, and a quickly growing store base. What's more, these trends point to continued earnings outperformance over other restaurant operators like Chipotle Mexican Grill (NYSE:CMG), Panera Bread (NASDAQ:PNRA.DL), and McDonald's (NYSE:MCD), Demitrios says.
