The focus of last week's preview was on oil and energy companies, and we saw that big oil had a good week, reporting better-than-expected results and record profits driven by high prices in the third quarter. Energy-related companies are well represented again this week and expectations in general remain high.

Early in the week, analysts surveyed by Thomson Financial anticipate that the big earnings gainers will include EOG Resources Inc. (NYSE: EOG), Anadarko Petroleum Corp. (NYSE: APC), and Cimarex Energy Co. (NYSE: XEC), which are expected to post profits of $2.24 per share (up 64.7% from a year ago), $1.48 per share (up 52.7%) and $2.26 per share (up 61.1%) respectively. All three of them have offered positive surprises in recent quarters, and analysts on average recommend buying EOG and Anadarko. Other expected big earnings gainers early in the week include Forest Oil Corp. (NYSE: FST), Pioneer Natural Resources Co. (NYSE: PXD), Comstock Resources Inc. (NYSE: CRK), and MasterCard Inc. (NYSE: MA). The earnings of phosphates producer Innophos Holdings Inc. (NASDAQ: IPHS) are expected to have risen 92.3% to $3.37 per share. Innophos beat estimates in the previous quarter by a whopping 210%, and analysts have been impressed with Innophos's lack of debt and pricing gains despite the slowing economy, so, on average, they recommend buying IPHS.

Also early in the week, analysts expect Goodyear Tire & Rubber Co. (NYSE: GT), Kaiser Aluminum Corp. (NASDAQ: KALU), and Oshkosh Corp. (NYSE: OSK) to report that their profits fell 52.9% to $0.33 per share, 45.1% to $0.67 per share, and 41.2% to $0.67 per share, respectively. These companies have tended to beat estimates in recent quarters, and the consensus recommendations of analysts are to buy them. However, PMI Group Inc. (NYSE: PMI), one of the largest private mortgage insurance providers in the U.S., is expected to take another hit as the housing slump drags on. The California-based company is expected to have widened its net loss from $1.04 per share a year ago to $2.43 per share in the most recent quarter. Its shares are down 84.5% from a year ago, and have been trading recently near their 52-week low.

With a turn of the calendar page, we drift into the middle portion of the current quarter, but the earnings season rolls on. Among the many companies scheduled to report quarterly results this coming week are Time Warner Inc. (NYSE: TWX), Cisco Systems Inc. (NASDAQ: CSCO), News Corp. (NYSE: NWS), and Whole Foods Market International (NASDAQ: WFMI). Let's take a look at which companies Wall Street analysts are expecting to be among the top earnings gainers and decliners this week.
