"Over the next five years the energy patch should offer some of the best investments around, and one standout is Schlumberger (NYSE: SLB)," says Stephen Leeb in The Complete Investor.

"Schlumberger, by a wide margin, is the best and most dominant. Its services range from well testing to pressure pumping to seismic testing, and it's No. 1 in virtually every area it occupies.

"Some of its operations, especially those that maintain the health of existing wells, are highly recession-resistant.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Amazon.com Inc. (NASDAQ: AMZN) reported strong Q1 results easily beat expectations.
• Bank of America Corp. (NYSE: BAC) posted better-than-expected Q1 earnings, helped by home refinancing.

Early this morning, oil firm Schlumberger (NYSE: SLB) reported earnings of 78 cents per share -- which was considerably lower than last year's same-quarter results of $1.09 per share. While the results were worse than a year ago, SLB managed to top the consensus estimate by three cents. Quarterly revenue totaled $6.0 billion, which was off from last year's revenue of $6.29 billion.

SLB, which is the world's largest oilfield services company, attributed the lower results to a slump in energy demand, which forced customers to reduce activity and search for price reductions. The company also noted that the rate of decline in its oilfield services division dropped considerably compared to the fourth quarter, thanks mainly to a sharp drop in the firm's North American natural gas rig count. SLB stated, "Our visibility on 2009 has not materially changed from the end of the fourth quarter."

"Many experts believe that oil prices are at unsustainably low prices now, and they expect a sharp rise in the commodity price as supply and demand come back into line again," says turnaround expert George Putnam.

In The Turnaround Letter, he suggests, "If oil does begin to rise again, the oilfield service stocks could rebound sharply." Here, he takes a look at large cap plays on a rebound within the oilfield services sector.

"We all know that oil prices have fallen dramatically from their highs in the summer of 2008. But different types of oil-related stocks have reacted quite differently to the price change in the underlying commodity.

"For example, while oil itself has dropped nearly 70% from its 12-month high, the stock of the largest integrated oil company, Exxon-Mobil (NYSE: XOM), is down only 26%, less than the stock market as a whole.

"Long term, supply remains the key issue to watch in the crude oil market; depressed prices continue to force producers to scale back on exploration and development spending," says energy expert Elliott Gue.

In The Energy Strategist, he says, "I watch oil service giant Schlumberger (NYSE: SLB) as a gauge of overall health in energy markets; it has its hands in just about every imaginable oil- or gas-producing market on the planet."

"Schlumberger's fourth quarter earnings release and conference call were far and away the most bearish from the company in at least five years.

"CEO Andrew Gould was notably downbeat, particularly during the analysts' question and answer (Q&A) session. Predictably, earnings estimates have plummeted since that call.

I think it's fair to say that there's much trepidation about the earnings season that picks up steam this week. And for better or worse, numbers from the big financials have begun to roll in. Last week we saw profit sink for JPMorgan Chase (NYSE: JPM) and significant losses from Bank of American Corp. (NYSE: BAC), Citigroup Inc. (NYSE: C), and Deutsche Bank (NYSE: DB).

Analysts surveyed by Thomson Reuters expect Bank of New York Mellon Corp. (NYSE: BK) to be among those financials reporting fourth-quarter earnings growth this week. They anticipate that Bank of New York will post a profit of $0.70 per share, compared to $0.67 per share a year ago and $0.72 in the previous quarter. Revenue is expected come to $3.8 billion, about the same as it was a year ago. Bank of New York has fallen short of earnings estimates in two of the past five quarters, by as much as 11.1%. For the full year, analysts are looking for $2.78 per share (+5.8%) on $14.8 billion (+4.2%). The consensus recommendation of analysts is to buy BK, and the long-term EPS growth rate forecast is 10.7%. Shares are 48.7% lower than a year ago. Other financials expected to report quarterly earnings growth this week include SunTrust Banks Inc. (NYSE: STI) and M&T Bank Corp. (NYSE: MTB).
