I'm Reiterating my Buy rating for Sunoco, Inc. (NYSE: SUN), first recommended on April 20, 2009 at a price of $26.58, but there are qualifiers, so close attention is warranted. If you bought SUN in April, you're up about 19%.

Sunoco has been hurt by the high oil price/low gasoline demand condition pervasive in the giant U.S. market that's squeezed margins. Further, Sunoco's primarily sweet crude oil refining operation prevents it from capitalizing on larger-margin sour crude refining. However, the sweet focus has enabled SUN to produce larger amounts of higher-grade products.

Sunoco, Inc. (NYSE: SUN) has underperformed, but I'm nevertheless Reiterating my Buy rating for the shares, first recommended on April 20, 2009 at a price of $26.58. Here's why:

Sunoco focuses on refining a relatively high percentage of higher-grade products, but demand has been depressed, due to the recession. Given a likely stabilization in U.S. gasoline demand later in 2009, revenue should rebound, which should send institution investors back into SUN.

The world is awash in oil. For now. Gasoline prices are at moderate levels. For now. And analysts say slack demand will keep a lid on gasoline prices this summer. Well, as the singer Meatloaf would say, two out of three ain't bad.

Given the continuing U.S. recession (which has taken many drivers off the road), all signs point to moderate gasoline prices for the duration of the summer, unless the unexpected occurs, such as a refinery outage or a damaging hurricane season. At that point gasoline prices could spike and begin to trend higher -- as they so often do in the summer -- exasperating many, unless you've purchased shares in Sunoco (NYSE: SUN).

Four weeks in a row of gains were met with at least the first day of the week having sellers win over buyers. The good news is that the market came back at the end of the day. We might have closed up if we had another hour of trading on the clock.

Geithner's comments about running out management and boards of directors at banks which need capital did not help, nor did an influential banking analyst coming out with very negative coverage of the sector at a new firm. Here were today's closing bell levels:

Dow 7,975.85 -41.74 (-0.52%)
S&P 500 835.48 -7.02 (-0.83%)

If you've been watching earnings this past week, or if you read last week's Week in Preview, then this coming week may leave you feeling a bit like Bill Murray in Groundhog's Day. That is, again analysts surveyed by Thomson Reuters expect earnings declines to be more frequent and deeper than earnings gains.

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.

Sun Microsystems (NASDAQ: JAVA) showed, once again, that it is one of the worst performing large-tech companies in America. The firm said its loss will be between 25 cents and 35 cents per share for the three months ended Sept. 28. Excluding one-time charges, the drop is between 2 cents and 12 cents per share. To make matters worse, it will probably take goodwill impairment charges for companies it has bought over the last two years. In other words, Sun paid too much.

Sun's revenue is also expected to be light, at about $3 billion.

It is old news to say that Sun has not come up with a single product compelling enough to get it out of the mud. Its servers are no better than those marketed by IBM (NYSE: IBM) or other large hardware companies. Corporate customers tend to go with the supplier that has the largest service force and best balance sheet.

The announcement does raise the question of why Sun is not being sold by its board. The stock trades at just above $5, down from a 52-week high of $24.08. So far this year, it is off nearly 70% while IBM is down only 12%.

Sun has a clean balance sheet with plenty of cash and modest debt. It would fit well with a number of larger companies that would like a larger part of the global server market.

Let the auction begin.
