Come on, not all retailers are created equal, they just trade like that. Home Depot (HD) , which was, quite curiously, downgraded today, might be a good opportunity ahead of its big weekend kickoff for gardening.
Costco (COST) has now sold off hard since the dividend.
I think that any of these could make sense and I am really partial to HD at the moment. Buy more and then if the group gets hammered again, buy more tomorrow.
