On Thursday, March 5th there are four notable earnings reports we keep an eye on. They include mining equipment maker Joy Global (JOY), supermarket chains Kroger (KR) and Fresh Market (TFM), as well as membership retailer Costco Wholesale (COST). The retailer recently ditched American Express (AXP) as its only accepted credit card in its stores, replacing it with Citigroup (C) and Visa (V) as its new partners. On the U.S. economic calendar, we point out nonfarm business productivity and unit labor costs, as well as the weekly jobless claims and factory orders.
