One of last week’s biggest winners was Skechers (NYSE: SKX), soaring 18.5% after posting stronger growth and heartier guidance than analysts were expecting. The footwear maker saw net sales climb 6% to $764.3 million during the fourth quarter. It’s true that 6% growth doesn’t sound very titillating, but Skechers’ own guidance three months earlier was calling for flattish top-line growth with just $710 million to $735 million in net sales for the period.
