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.

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.

MOST NOTEWORTHY: Goldman Sachs, Alexza Pharma and SAP AG were today's noteworthy upgrades:

• Wachovia upgraded Goldman Sachs (NYSE: GS) to Outperform from Market Perform, as they believe Goldman has a superior capital position relative to competitors and will likely benefit more than any firm from Bear Stearns' (NYSE: BSC) collapse. They have a $180-$185 target range for the stock.
  
• Following Alexza Pharma's (NASDAQ: ALXA) Q4 report, JMP Securities said they have reduced concerns regarding Loxapine timelines and risks. The firm raised Alexza to Outperform from Market Perform.

Among the companies reporting on Monday were Verizon Communications Inc. (NYSE: VZ), SanDisk Corp. (NASDAQ: SNDK), and Tyson Foods Inc. (NYSE: TSN).

Verizon reported fourth-quarter earnings that were in line with expectations of analysts surveyed by Thomson Financial. The company earned $1.07 billion, or 37 cents per share, in the period ending in December, compared to $1.03 billion, or 35 cents per share, in the same period a year earlier. Excluding charges for severance costs related to layoffs and a loss on the sale of Verizon's operations in the Dominican Republic, the latest earnings were 62 cents per share.

Revenue for the fourth quarter was $23.8 billion, up 5.5% from $22.6 billion a year ago. The average analyst forecast had been $23.96 billion. For all of 2007, Verizon earned $5.5 billion, or $1.90 a share, on $93.5 billion in revenue, compared to a profit of $6.2 billion, or $2.12 a share, on $88.2 billion in revenue the year before.

Shares were up almost 1% on Monday, to close at $38.11. Shares were at 52-week low of $35.40 last week.

Proxy Governance Inc. has recommended that shareholders withhold their support for the board of directors at Tyson Foods, Inc. (NYSE: TSN), in light of excessive executive compensation in the face of operational underperformance.

Tyson has underperformed its peer group over the past few years, and Proxy argues that the company's management has not done enough to respond to industry challenges including increased feed costs and export restrictions on beef.

In 2007, Tyson stock declined in value while Richard Bond was paid $24.6 million. Tyson says that "it's apparent they haven't done all their homework." But I think that a CEO getting paid $24.6 million while presiding over the destruction of shareholder value is indicative of a compensation committee that hasn't done its homework: Proxy estimated that Tyson chief executives have been paid 82% more than CEOs at other companies in the peer group.

Executive pay is, as a whole, so out of touch with reality that any company that is overpaying so egregiously that it gets the attention of a proxy advisory firm really doesn't have a leg to stand on. Hopefully Tyson shareholder will send a message to the board.
