Many shoe sellers saw sales slow as the fall shopping season wrapped up earlier this month. But for investors, that could lead to new buy opportunities. Skechers (SKX) stumbled 8% on Sept. 17 in huge volume after Sterne Agee cited a sharp slowdown in weekly sales, but said it was a temporary issue stemming from the end of back-to-school sales. The analyst maintained a buy rating and 70 price target on the stock.
