Also, Peter Cohan points out that a bear market means low earnings expectations, and also that negative surprises are likely to outweigh positive ones in the second half of the year. Aaron Katsman, on the other hand, predicts a rebound for earnings in the second half. And BusinessWeek reminds us that cheap stocks -- even with big names such as Ford Motor Co. (NYSE: F), Sprint Nextel Corp. (NYSE: S), and Northwest Airlines (NYSE: NWA) -- are no bargain if they have no earnings.

Upcoming results to watch for include Alcoa (NYSE: AA), Pepsi Bottling Group (NYSE: PBG), Marriott International (NYSE: MAR), and General Electric (NYSE: GE).
