While the release of economic data doesn't stop next week (see economic schedule highlights below), the earnings season does wind down dramatically. Most of the S&P 500 companies already have reported on the past quarter, which means dismal earnings news is largely behind us, at least for a while. About the only companies of note expected by analysts surveyed by Thomson Reuters to report falling earnings this week are Costco Wholesale Corp. (NASDAQ: COST), Wendy's/Arby's Group Inc. (NYSE: WEN), Foot Locker Inc. (NYSE: FL), Bank of Montreal (NYSE: BMO), and Steinway Musical Instruments Inc. (NYSE: LVB).

While PetSmart Inc. (NASDAQ: PETM) and Big Lots Inc. (NYSE: BIG) quarterly profits are expected to be about the same as a year ago, Liz Claiborne Inc. (NYSE: LIZ), Kenneth Cole Productions Inc. (NYSE: KCP), Ciena Corp. (NASDAQ: CIEN), and Trina Solar Ltd. (NYSE: TSL) are expected to have swung to losses in the most recent quarter.

While other earnings may have disappointed last week, the news was good for oil giant ConocoPhilips (NYSE: COP). In what some took as a good sign for big oil, the Houston-based company reported that third quarter net income surged 41% year over year to $3.39 per share, and that revenue also surged 52% to $70 billion. We'll see whether the good news extends to other petroleum giants scheduled to report quarterly results this week.

Analysts surveyed by Thomson Financial are looking for BP (NYSE: BP) profits to have grown 43.2% in the most recent quarter to $2.34 per share on revenue of $109.7 billion, and Chevron Corp. (NYSE: CVX) to post earnings up 39.4% to $3.25 per share on revenue of $86.8 billion. Marathon Oil Corp. (NYSE: MRO), ExxonMobil Corp. (NYSE: XOM), and Royal Dutch Shell (NYSE: RDS.A) likewise are expected to report higher net income of $2.33 per share (sales of $23.4 billion), $2.40 per share (sales of $131.4 billion), and $2.65 per share, respectively. Even Valero Energy Corp. (NYSE: VLO) is expected to post earnings slightly higher to $1.46 per share (sales of $36.4 billion), despite the effects of Hurricane Ike. Among these companies, only BP and Valero beat earnings expectations in the previous quarter. Not surprisingly, analysts on average recommend buying all except Valero, and shares of all of these companies have recently hit 52-week lows.
