I'm Reiterating my Buy rating for Tesoro (NYSE: TSO), first recommended on April 23, 2009 at a price of $14.30.

Tesoro's Q2 performance disappointed, but the New York Rangers will win the National Hockey League's Stanley Cup again before I'll sell a U.S.-based refiner.

A new U.S. administration's promise to create a more self-reliant, energy-independent nation and the impact of efforts to first limit, then eliminate global warming from fossil fuels opens the door to alternative energy source development.

But, as Saudi Arabia reminds us, barring a breakthrough technology, fossil fuels will remain a major energy source for at least the next thirty to fifty years. In other words, oil is down now, but it's not out and it isn't going away anytime soon, which is why investors who can tolerate moderate risk should consider Tesoro (NYSE: TSO).

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.

SuccessFactors (NASDAQ: SFSF): The stock prices secondary at $11.80 and is holding pretty tough. I'm watching this one pretty closely and was hoping for some post-secondary weakness to possibly add a starter here. A pretty good balance sheet just got better, but I guess the question is, "What is it going to do with that cash?"

Digital TV Holding (NYSE: STV): This company may have made a bottom recently and the deal announced today is exactly what the company talked about in its last quarterly call. I've commented on the possibility of it securing more revenue streams (partnering for recurring advertising revenue) in the past. It looks to be developing the conduits to deliver on that.

comScore (NASDAQ: SCOR): Google (NASDAQ: GOOG) news is hurting the stock badly. I sold my mine some time back after that series of paid click reports ahead of Google's last quarter that proved to be quite inaccurate. All that aside, I don't think comScore's core business is going to disappear within a compressed time frame and may be worth a long side trade if it moves near or under $20. I'll leave it be and see what develops, as the knife could cut further.

Over the past year, we have been hearing a lot of news about soaring crude oil prices. The easiest thing that we could think about is investing our money into independent oil refiners. Companies such as Frontier Oil (NYSE: FTO), Valero Energy (NYSE: VLO), Tesoro (NYSE: TSO), Alon USA Energy (NYSE: ALJ) or Western Refining (NYSE: WNR) are among those potential stocks on the waiting list.

Though it may seem surprising, Kiplinger.com advises us of exactly the opposite. Kiplinger underlines the fact that refiners represent a way to loose a lot of money... contrary to pipelines, oil producers and energy service companies. This came as the result of people's needs to transform crude oil into gasoline, diesel, jet fuel or heating oil.

The big difference between the cost of crude and the price of refined products is called the "crack spread", and this is where the problem comes in. In May of last year, the crack spread peaked at $27, and even moved up as high as $40 in some locations. This compares to the historical norm of closer to $20. But starting with the spring of 2007, things started changing, and the spread began to narrow... now the spread has fallen down to around $8.50 for some companies.

Tesoro Corporation (NYSE: TSO) stock is falling this morning after billionaire investor Kirk Kerkorian's Tracinda said today that the company's decision to adopt a "poison pill" shareholder rights plan could jeopardize Tracinda's decision to acquire a 16% stake in the company. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on TSO.

The stock hit its 52-week high of $65.98 in October and set its 52-week low of $31.46 in January. This morning, TSO opened at $54.00. So far today the stock has hit a low of $53.14 and a high of $55.49. As of 12:15, TSO is trading at $53.71, down $2.18 (-3.9%). The chart for TSO looks bullish and possible trend reversal while S&P gives TSO a negative 2 STARS (out of 5) sell rating.

For a bearish hedged play on this stock, I would consider a January bear-call credit spread above the $65 range. A bear-call credit spread is an options position that combines the purchase and sale of call options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 4.2% return in 9 weeks as long as TSO is below $65 at January expiration. Tesoro would have to rise by more than 21% before we would start to lose money.

News of corporate stupidity rarely shocks me, but this insensitive, silly, and stupid case does: The Associated Press coverage of the incident involving Tesoro (NYSE: TSO) pretty much sums it up:

LODI, Calif. -- A gas station cashier who was held up on the job and helped track down the robber has been fired.

The company that owns the station said Cynthia Lopez lost her job because her cash drawer was $16 over its $50 limit.

If you've recovered from the panic attack you just suffered as a result of this shocking news, consider the explanation given by the company's spokesperson: "We do have policies on cash limits in registers to protect our employees' safety. We have a zero-tolerance policy."

So an employee's safety was jeopardized over $16? It's a good thing it wasn't $27 or it could have started World War 3. This woman, who was threatened by a masked robber at gunpoint, had the presence of mind to jot down the license plate number of the getaway car, and note the man's clothing.

If you're as disgusted by this case of corporate stupidity as I am, send an e-mail to the company, and let's try to help Cynthia Lopez get her job back.

In his Block Traders Oil & Gold Monitor, advisor Peter Way follows hedge fund and block traders to find stocks with the best prospects.

He explains, "When we look at the guys hedging trades in crude oil futures, it tells us they see far more upside for crude than downside."

Meanwhile, he adds, it looks like the oilpatch stocks should continue in a favorable environment. He notes that many attractive investment prospects are to be found in the smaller independent oil exploration and production (E&P) stocks.

The advisor explains, "These are typically companies that have their own reserves in the ground, and benefit from the industry's supply/demand imbalance situation like the majors. They may acquire each other or be acquired by major producers as the need for and value of reserves becomes even more obvious and pressing in the future."

Among those that appear to have better potential, he believes, are Holly Corp. (NYSE: HOC), along with Tesoro (NYSE: TSO). He observes that both are benefiting from a long-term inadequacy of refining capacity in the US.

Peter Way adds, "Their current value is not in reserves, but in a fattening of profit margins in the process chain from upstream operations (reserves and extraction) to downstream (refining and distribution)."

Overall, he notes, "Given the worldwide energy reserves shortage and the high crude and natural gas prices it engenders, this fattening is not likely to be a temporary condition."
