Analyst Upgrades

• BB&T (BBT) and Aflac (AFL) to buy from hold at Deutsche Bank.
• Kodiak Oil & Gas (KOG) to outperform from neutral at RW Baird.
• Zhongpin (HOGS) to neutral from reduce at Global Hunter.
• Marathon Oil (MRO), Noble Energy (NBL) and Manulife Financial (MFC) to buy from neutral at UBS.
• Carrizo Oil & Gas (CRZO) to buy from hold at Canaccord.
• Comerica (CMA) to buy from neutral at Rochdale.

Institutional investors (IIs) have made up for lost time with Marathon Oil Corp. (MRO), first discussed here on April 20, 2009, at a price of $28.55. The shares have surged higher this winter, rising from about $35 to about $49.

Hence, it goes without saying that now would be a good time to consider taking some profits off the table with MRO, if you're in at/near $28.55.

However, those investors who can tolerate the risk can maintain their full position with MRO and go for an even bigger gain.

Analyst upgrades:

• Verizon (VZ) to conviction buy from buy at Goldman.

It will be a busy week. Republicans are poised to gain control of the House of Representatives and gain governorships in Tuesday's mid-term elections. Also, the Federal Reserve is expected to announce another round of quantitative easing Wednesday, following the FOMC meeting. Major retailers are scheduled to report October same-store sales Thursday, while the October unemployment rate, announced on Friday, is expected to remain at 9.6%.

Toyota's (TM) fiscal second-quarter results will be one of the highlights on the earnings front this week. After three periods of way underestimating Toyota's earnings, have the analysts surveyed by Thomson Reuters got it right this time? The stock sure could use a boost. Teva Pharmaceuticals (TEVA) is in a similar situation; i.e., high expectations for this week's quarterly results but a stock in need of a boost. Marathon (MRO) and Starbucks (SBUX) are also expected to post strong earnings growth this week, but both stocks are riding high.

It's a difficult call, but I'm Reiterating my Buy rating for Marathon Oil (NYSE: MRO), first recommended on April 20, 2009 at a price of $28.55.

Marathon's stock has meandered, largely due to reduced demand for Marathon's heavy/sour crude -- a negative trend that's likely to continue through at least mid-Q3.

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

• Akamai Technologies Inc. (NASDAQ: AKAM) earnings prospects garnered an analyst's upgrade.
• Applied Materials Inc. (NASDAQ: AMAT) warned of a loss for the quarter due to the economic slowdown.
• Burger King Holdings Inc. (NYSE: BKC) posted lower Q2 profit and revenue that missed estimates.
• Clorox Co. (NYSE: CLX) Q2 profit fell but beat estimates, and it reaffirmed its full-year guidance.
• Dow Chemical Co. (NYSE: DOW) swung to a Q4 loss and warned that low demand will continue.
• Hartford Financial Group Inc. (NYSE: HIG) posted a loss, cut its dividend, and offered weak guidance.

Both Northrop Grumman Corp. (NYSE: NOC) and Marathon Oil Corp. (NYSE: MRO) Tuesday reported losses in their respective fourth quarters due to large impairment charges.

Los Angeles-based defense contractor Northrop posted a loss of $2.54 billion, or $7.76 per share, compared with a profit of $457 million, or $1.32 per share, in the same period a year earlier. Results were hurt by a $3.06 billion charge related to overestimating the value of past acquisitions in its shipbuilding and space operations.

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.

Motorola Inc. (NYSE: MOT), Dow Chemical Co. (NYSE: DOW), Anadarko Petroleum Corp. (NYSE: APC), IAC Interactivecorp (NASDAQ: IACI), Moody's Corp. (NYSE: MCO), Elizabeth Arden Inc. (NASDAQ: RDEN), Devon Energy Corp. (NYSE: DVN), Diebold Inc. (NYSE: DBD), Tyco International Ltd. (NYSE: TYC), United Parcel Service (NYSE: UPS), Cisco Systems Inc. (NASDAQ: CSCO), Polo Ralph Lauren Corp. (NYSE: RL), ITT Corp. (NYSE: ITT), and Walt Disney Co. (NYSE: DIS) are scheduled to report quarterly results this week, and they're all expected to report double-digit declines in earnings.

But again this week, let's take a look who Wall Street feels may have done well in the past 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.

TheStreet.com's Jim Cramer says you have to be bullish on the commodity when we're using more of it than ever, it's running out and $100 a barrel doesn't even sound crazy anymore.

Can you trust the International Energy Agency to be right about how oil demand will be blunted by high prices and how consumption will decline?

First, let's deal with demand. I haven't seen any slowing in demand in any of the indicators I use, in part because gasoline hasn't kept pace with the commodity. Cars, certainly, haven't made any strides in using less gasoline, and news right now out of Ford (NYSE: F) (Cramer's Take) is that there's really been no progress whatsoever.

How about heating demand? I have seen no switch whatsoever to another fuel because of the rise. Not one bit, or you would see a nat gas rally.

How about power plant demand? I am willing to think that some power plant manufacturers will debate switching, but building a new coal plant is something no one feels comfortable with without new standards. Nothing's happened along these lines, though.
