Alcoa Inc. (NYSE: AA) kicks off the new earnings seasons when it reports third quarter results on Tuesday. The Pittsburgh-based aluminum producer, which celebrated its 120th anniversary with the launch of its website, is expected to post a profit of 54 cents per share, down 15.6% from the same quarter of last year, on revenue of $7.2 billion, down 2.1%. While Alcoa has tended to fall short of estimates in recent quarters, in the second quarter it did offer a positive surprise of almost 3%. Its long-term earnings per share growth forecast is 14.8%, a little less than the S&P 500, and analysts polled by Thomson Financial on average recommend buying Alcoa, and have for more than 90 days. Shares reached a new 52-week low last week, and are down 48.9% from a year ago.

General Electric Co. (NYSE: GE) is also expected to report a slip in earnings this week. Analysts anticipate that the conglomerate will post a third-quarter profit of 45 cents per share, down just 6.3% from a year ago, on revenue of $47.7 billion, which is up 12.1%. GE has tended to eke out small positive surprises in recent quarters, by less than 1% in the second quarter. GE's long-term earnings per share growth forecast is only 11.0%, which is less than the sector average and the S&P 500. The consensus recommendation has recently swung to hold GE, but Warren Buffett has bought in to the tune of $3 billion. GE also reached a new 52-week low last week as the markets tumbled. GE shares are down 48.1% from a year ago.

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).
