Walgreen (WAG) is down 1.9% after reporting FQ4 results. Investors could be upset over remarks about "no substantial progress" being made in Walgreen's contract renewal negotiations with Express Scripts (ESRX). Walgreen announced in June it didn't expect to be part of Express Scripts' pharmacy provider network after this year.
