The shares of food producer Tyson Foods (TSN), first discussed on May 11, 2009 at a price of $12.35, have meandered this summer, but that sideways action does not change the positive story, and I obviously still like the shares here.

Tyson's 2010 revenue should increase about 3-4% as food demand rises in-sync with the U.S. and global economic expansions. Chicken and beef margins should widen. Modest pricing power also will occur.

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

• Blockbuster Inc. (BBI) Q1 net loss was in line with estimates and same-store sales declined, shares also fell.
• CA Inc. (CA) shares sold off on high volume following the Q4 earnings miss and disappointing guidance.
• Cigna Corp. (CI) reported better-than-expected Q1 earnings and higher revenue, and reaffirmed its full-year outlook.
• Cisco Systems Inc. (CSCO) beat Q3 earnings and revenue expectations in the "strongest quarter in our history."
• Dean Foods Co. (DF) lower Q1earnings beat analysts' estimates, but shares fell on heavy volume afterward.
• Denny's Corp. (DENN) bested consensus estimates and year-ago EPS by a penny, but said same-store sales fell.

Tyson Foods' (TSN) stock has meandered since first recommended on May 11, 2009 at a price of $12.35, but I'm sticking with the stock. Here's why:

First, Tyson has the product diversity to adjust to increasingly demanding, educated U.S. consumers, who may, for example, favor chicken over pork one month, then do an end-run and return to red meat when steak prices drop.

Pigs at the Minnesota state fair have tested positive for the H1N1 "swine" flu virus in preliminary tests.

Confirmation tests are pending, but this could be bad news and cause panic within the pork industry. Pork belly futures and companies like Smithfield Foods (NYSE: SFD), Tyson (NYSE: TSN), and Hormel (NYSE: HRL) are a few that could be affected.

Tyson Foods (NYSE: TSN) is up 9% in early afternoon trading as I write this. The company's second-quarter earnings release is driving the buying. According to this article, Tyson reported an adjusted loss of $0.05 per share. The market was expecting a loss of $0.06 per share. So I guess the market was pretty happy about that.

Wall Street was probably encouraged by something else as well. If you take a look at the actual release, head on down to the statement of cash flows. Last year at this time, Tyson generated $144 million in cash from operations during the six-month period. This year, the company made $407 million from operations. Some nice changes in working capital helped out.

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

• Amazon.com Inc. (NASDAQ: AMZN) shares surged after earnings easily topped Q4 expectations.
• AT&T Inc. (NYSE: T) reported that its Q4 earnings fell while its revenue rose marginally.
• Boeing Co. (NYSE: BA) posted a big loss and lower revenue due to strikes and design changes.
• Caterpillar Inc. (NYSE: CAT) reported that Q4 profit fell despite higher revenue and lowered its guidance.
• Danaher Corp. (NYSE: DHR) lower Q4 profit topped analysts' estimates, sending shares higher.
• Eastman Kodak Co. (NYSE: EK) reported a Q4 net loss and announced additional job cuts.

Here's a quick look at some of Monday's earnings results:

Netflix Inc.'s (NASDAQ: NFLX) fourth-quarter earnings jumped 45% percent to nearly $23 million, or 38 cents per share, which surpassed analysts' estimates. Revenue in the period rose 19% to $360 million. The company ended 2008 with 9.4 million subscribers, a gain of 718,000 customers from the end of September. Shares fell $0.29, less than 1% Monday.

Amgen Inc.'s (NASDAQ: AMGN) fourth-quarter profit grew 15% percent to $961 million, or 91 cents per share, mostly due to lower expenses. Revenue was $3.75 billion about the same as last year. Results included $60 million in restructuring costs a year ago. Shares rose $1.22, or 2.3%, but fell in after-hours trading.

Egg producer Cal-Maine Foods Inc. ( NASDAQ: CALM) reported on Monday that its fiscal second-quarter earnings fell 32% to $27.2 million, or $1.14 per share. Revenue rose 7% from a year ago to $238.3 million.

Analysts surveyed by Thomson Financial had on average expected a $1.26 per share profit. The company said sales to the institutional and food-service sector in the quarter ended Nov. 29 were slower while feed costs remained high. They added that those prices are likely to remain relatively high and volatile over the year ahead.

Shares fell Monday by $1.97, or 6.7%, and continued to fall in after-hours trading. The share price is still up 4.4% in the past three months, and about the same as it was a year ago.

Shares of rivals Kraft Foods Inc. (NYSE: KFT), Tyson Foods Inc. (NYSE: TSN), and ConAgra Foods Inc. (NYSE: CAG) also declined on Monday.

Based in Jackson, Miss., Cal-Maine is one of the largest fresh shell egg producers in the U.S., selling its products to supermarkets in 29 states. It has a market cap of $588.4 million and its operations include breeding facilities, hatcheries, wholesale distribution centers, feed mills, shell-egg production facilities, pullet-growing facilities, and processing and packing facilities.

Pilgrim's Pride's home roots in the small town of Pittsburg, Texas, perhaps explain why it is the largest chicken producer in the U.S., even ahead of competitor Tyson Foods, Inc. (NYSE: TSN) in Arkansas. In 1946, Lonnie "Bo" Pilgrim dressed like a standard Pilgrim and tucked a small chicken under his arm when completing orders for customers. He gave away free chicks when he sold chicken feed as a way to expand his market for chicken feed. As of today, Pilgrim's Pride operates chicken processing plants in 13 states and Mexico and processes 44 million chickens per week, resulting in 9 billion pounds of chickens per year and over 528 million chicken eggs per year.

Pilgrim's Pride's operations are almost exclusively located in the U.S. close to its farms, and it has become the second-largest chicken supplier to Mexico as well. It does have processing plants in Mexico and Puerto Rico. Along with such huge chicken-producing numbers come a few problems, as a huge product recall in 2002 due to Lysteria contamination killed seven people and made over 40 customers sick. In 2004, more than 24,000 hens were destroyed after a strain of avian flu was found in Hopkins County, Texas.

Pilgrim's Pride is still based in the same location where it was founded over 60 years ago, but today stands as a completely vertically-integrated company: it owns every process and facility from egg to table, as it says. Wal-Mart Stores Inc. (NYSE: WMT), Publix Super Markets (OTC: PUSH) and KFC, a division of Yum! Brands (NYSE: YUM) ,can be counted as some of Pilgrim's Pride's largest customers.

Like most big companies located in small towns, Tyson Foods (NYSE: TSN) has a delightfully quirky origin. John Tyson, owner of a battered truck and 500 chickens, opportunist, and debtor in the Depression-era 1930s struck an idea that probably seemed like folly to his neighbors: he'd deliver chickens to Chicago and Kansas City, where they'd get more money.

I'm sure for every story like Tyson's, there were 100 that didn't turn out so auspiciously. But in this tale, the hero comes back to his little Arkansas hometown with a profit and pays off his debts. He keeps on raising and selling birds in points north, eventually devising a plan to keep more of the profits by "vertically integrating" (I'll bet dollars-to-doughnuts he didn't call it that) and incubating his own chicks instead of buying them from a hatchery, as well as milling his own feed instead of buying it from a feed store.

This wasn't the end of Tyson's forethought. He bought a broiler farm in Springdale, Arkansas (beginning the company's history in that town) and started to cross-breed birds designed for meat production, instead of using heritage (or "pedigree") breeds.
