Retailers were rocked on Friday with the five worst performing industry groups all in the retail space. The S&P Retail index (XRT) dropped nearly 4% on Friday and more than 8% last week. Many of the retail industry groups and stocks within those groups are at or challenging October 2014 lows on the heels of a poor monthly retail sales report that was released in pre-market action on Friday. One of those companies, Dick’s Sporting Goods (DKS), is testing an area of price support it’s tested on several previous occasions over the past 3-4 years.
