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.

We at BloggingStocks and everywhere else make the full gambit of prognostications, suggestions, predictions, guesses, analogies, and so forth in an attempt to improve potential investment opportunities for all our readers and provoke discussion.

All of this has its limits, but, if you are a fan of Professor Nassim NicholasTaleb and his best seller The Black Swan then you already have been warned that the events that have the greatest impact on our lives and our investments are most often unpredictable. We cannot predict the future nor can we anticipate the tragedies that will tank our portfolio's.

While I do believe predicting the future is, how should I say, futile, there are general clues as to which way the wind blows.

The earnings crunch continues this week, and analysts surveyed by Thomson Reuters are anticipating lots of strong quarterly reports.

For example, year-over-year earnings growth from big oil Chevron (CVX), ConocoPhillips (COP), ExxonMobil (XOM) and Royal Dutch Shell (RDS.A) are expected to be in double digits. The same is true of many other energy and mining concerns reporting this week: Allegheny Technologies (ATI), Alliant Energy (LNT), Arch Coal (ACI), Cliffs Natural Resources (CLF), CMS Energy (CMS), CONSOL Energy (CNX), DPL (DPL), Hess Corp. (HES), Minerals Technologies (MTX), Pioneer Natural Resources (PXD), PPL Corp. (PPL), Southwestern Energy (SWN), Total (TOT), Whiting Petroleum (WLL), Williams Companies (WMB) and Wisconsin Energy (WEC).

Yesterday I began a review of the five major U.S. defense contractors, searching for potential stock value. The group included General Dynamics (GD), Lockheed Martin (LMT), Boeing (BA), Northrop, Grumman (NOC) and Raytheon (RTN). After examining the P/E, PEG, P/CF, P/S, and P/B, Boeing did not make it through the screens.

Today I continue the exercise, hoping to find a stock worthy of placing a bet.

Dividend Yield

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

The defense sector is down, but don't count it out. We give lip service to the likelihood of defense being a target of budget hawks in Congress, but truth be told, the same fiscally conservative members are often the biggest supporters of defense.

Equally important is that unlike many other industries, this is one tech sector that keeps most of its jobs at home and well-distributed through the country. This, too, preserves defense spending.

The major players in the industry after 20 years of consolidation are General Dynamics Corp (GD), Lockheed Martin (LMT), Boeing Co (BA), Northrop, Grumman (NOC), and Raytheon Company (RTN). In addition there are hundreds more making specialized parts in support of the majors and more still supplying basic elements like tires, wiring, computer processors, steel, aluminum, specialty glass, and ammunition. Then there are suppliers of manpower and smaller manufacturers producing unmanned aircraft drones and robots.

"In our newsletter, we maintain numerous model portfolios based on the strategies of leading investors, such as Warren Buffett, Ben Graham and Peter Lynch," explains John Reese.

The editor of Validea asserts, "Our Kenneth Fisher-based Portfolio has shown a 7-year annualized return of 11.9%; this approach focuses on a metric Fisher pioneered: the price/sales ratio.

"While investors for decades relied heavily on the P/E ratio, Fisher found that earnings -- even the earnings of good companies -- can fluctuate greatly from year to year.
