With earnings season in full swing, the FOMC meeting on interest rates, the GDP estimate, and housing numbers due out, the coming week is shaping up to be a busy one. So here's a peek at what's on the economic calendar.

Monday

Quarterly reports from American Express (AXP) and McDonald's (MCD) will highlight Monday. Amgen (AMGN), CSX (CSX), Halliburton (HAL) and Texas Instruments (TXN) are also expected to report strong earnings results.

"Aerospace & defense contractor General Dynamics (GD) is a buy based on our value criteria," says J. Royden Ward.

The editor of Cabot Benjamin Graham Value Letter explains, "In our view, the shares are undervalued at 9.4 times forward 12-month EPS. Dividends have been paid since 1979 and currently provide a solid yield of 2.5%

"The company has an impressive record of increasing sales, earnings and dividends during the past 20 years which will continue unabated during the foreseeable future.

The list of stocks has been whittled down to four. Chevron Corporation (CVX) made the cut to become the oil company stock. Three defense sector powerhouses are competing for one spot in Chasing Value: 2011 Stock Picks -- The Journey Begin.

Today we take a more comprehensive view returning to earlier metrics, and adding some other criteria in order to reach a conclusion. This series began with the contention that making specific predictions was a fools errand with the danger to your portfolio coming from "black swans". To try and add some general counter measures to this possibility I decided that the defense and oil sectors might provide protection against the greatest of threats, war and terrorism. On that basis I posted Chasing Value: You Must Own Defense and Oil for Safety.

The list of stocks under consideration has been reduced from eleven to ten, to seven and now in today's story four. Starting with five major defense contractors and six major oil companies (see Chasing Value: You Must Own Defense and Oil for Safety), I began a search to find one stock in each sector that might be suitable for inclusion in my list of 2011 stock picks posted last week Chasing Value: 2011 Stock Picks -- The Journey Begin.

Today we continue our analysis by examining return on equity (ROE), return on invested capital (ROIC), and price-to-earnings-to-growth (PEG). Each stock is ranked by sector and metric from best to worst. Sometimes there are clear winners and others there is little to separate one stock from the next. However, in total, a picture can be drawn that does portray a superior opportunity.

This series started with five major defense contractors and six major oil companies that are worthy considerations to help your portfolio survive a global crisis (see Chasing Value: You Must Own Defense and Oil for Safety). After the first review, one stock was eliminated from consideration: Petroleo Brasileiro (PBR). The reason is in the first story.

Today we continue our analysis by examining price-to-book (P/B), price-to-cash-flow (P/CF), and dividend yield. Each stock is ranked by sector and metric from best to worst. In the end we hope to narrow down our choices for candidates that might be added to Chasing Value: 2011 Stock Picks -- The Journey Begins.

• Lockheed Martin: 3.77%
• Raytheon Company: 3.16%
• Northrop, Grumman: 2.89%
• General Dynamics: 2.59%

Analyst Upgrades

• Credit Suisse upgraded Netflix (NFLX) to neutral from underperform and raised its price target to $140 from $90. The firm's survey work indicates Netflix's streaming offering is compelling and will continue to grow as it acquires additional streaming content.
• Barclays upgraded Ford (F) to overweight from equal weight, citing the company's earnings power, reduced cost base, expectations for a return to prior peak margins and valuation. The firm raised its target to $16 from $15.
• Merriman upgraded OpenTable (OPEN) to buy from neutral based on increased visibility into international expansion from the toptable.com acquisition and upside from its Spotlight product.
• Siemens (SI) was upgraded to conviction buy from buy at Goldman.
• Medicis (MRX) was upgraded to buy from hold at Jefferies.
• IDEX (IEX) was upgraded to outperform from neutral at Baird.

Northrop Grumman (NOC) may be a U.S. Air Force favorite, but it does not deserve a place in your portfolio right now.

Northrop announced it received an indefinite-delivery/indefinite-quantity (ID/IQ) award from the Air Force that has a potential value of $919 million collectively over 10 year. Northrop will compete to provide mission planning software systems and tools that enable warfighters to plan missions and transfer required data to aircraft avionics.

Unfortunately for Northrop, this announcement was overshadowed by Goldman Sach's announcement that it has added Northrop to its "conviction sell" list today.

Frankly, even with the announcement of this new contract, I agree with the folks at Goldman. Northrop has been in a persistent downtrend since the end of April and is continuing to form lower highs and lower lows. A temporary support level has established itself at $54, but I don't expect this level to hold up for long.

Analyst Upgrades

• Deutsche Bank upgraded Barrick Gold (ABX) to buy from hold and reiterates a buy rating on Newmont Mining (NEM) after upping its 2011 gold forecast to $1,450 per ounce and 2012 forecast to $1,600 per ounce. The firm upped its target for Barrick shares to $53 from $45, for Newmont shares to $74 from $72, and on hold-rated Goldcorp (GG) and Kinross Gold (KGC) to $40 and $20, respectively.
• Citigroup upgraded General Dynamics (GD) to hold from sell following the recent pullback in shares. The firm keeps a $67 price target for the stock.
