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.

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

• Applied Materials Inc. (NASDAQ: AMAT) posted better-than-expected Q3 results, sending shares higher.
• AutoDesk Inc. (NASDAQ: ADSK) reported better-than-expected Q2 earnings, sending shares higher.
• Blockbuster Inc. (NYSE: BBI) had another disappointing quarter as same-store sales declined.
• CIT Group Inc. (NYSE: CIT) delayed its Q3 report due to ongoing debt restructuring and a possible bankruptcy.
• Dr Pepper Snapple Group Inc. (NYSE: DPS) Q2 earnings came in well ahead of Wall Street expectations.

Hormel Foods Corp. (NYSE: HRL) pleased Wall Street this morning with an upwardly revised 2009 forecast. Thanks to a strong third-quarter performance from its Jennie-O turkey unit, along with solid results in its refrigerated foods and grocery products divisions, Hormel now expects fiscal 2009 earnings of $2.36 to $2.42 per share.

"We also benefited from better investment performance in our rabbi trust," commented Chairman, President, and CEO Jeffrey M. Ettinger in a company release.

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

• AnnTaylor Stores Corp. (NYSE: ANN) reported a smaller-than-expected Q1 loss as sales slumped.
• Barnes & Noble Inc. (NYSE: BKS) smaller-than-expected Q1 net loss sent shares higher.
• Children's Place Retail Stores Inc. (NASDAQ: PLCE) solid Q1 results were in line with expectations.
• Dick's Sporting Goods Inc. (NYSE: DKS) posted higher-than-expected Q1 results but same-store sales fell.
• Gap Inc. (NYSE: GPS) lower Q1 earnings beat expectations and lower revenue was in line.

Hormel Foods (NYSE: HRL) hasn't been a bad stock. Its recent performance is firmly in the green. Shares of Hormel have increased in value by 8% year-to-date. Over the last six months, the stock is up by roughly 16%.

Now we come to the food entity's second-quarter report, which was issued on Thursday. Do the numbers indicate that the stock will continue to trend higher? Or is now the time to sell?

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.

I remember Toronto during SARS. As one of the harder hit areas, it was not a happy place. It was the end of winter, but that miserable, cold winter just didn't want to end. People walked the streets in a gloomy haze, afraid to take the subway and giving dirty looks to anyone brazen enough to cough in public. Worse, I couldn't even visit a friend in the hospital. All things considered though, in global pandemic terms, it was over relatively quickly. Let's hope swine flu will be the same.

In the meantime, let's put on our investors hats and see what's in store for some stocks:

Travel and tourist stocks
This is one of the worst hit areas, especially airlines, as people may cancel their travel plans. For example, AMR Corp. (NYSE: AMR) traded over 9 percent lower an hour after the open. Royal Caribbean Cruises (NYSE: RCL) was down over 15 percent. In fact UBS downgraded these airlines and hotels this morning: AMR, Continental Airlines (NYSE: CAL), Host Hotels and Resorts (NYSE: HST), Lasalle Hotel Properties (NYSE: LHO), Marriott (NYSE: MAR), United Airlines (NASDAQ: UAUA), US Airways (NYSE: LCC). Carnival Cruise Lines (NYSE: CCL) also declined considerably. Best to stay away from the sector.

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

• Bidz.com Inc. (NASDAQ: BIDZ) Q4 earnings release included notice about an SEC investigation.
• Dell Inc. (NASDAQ: DELL) saw net income drop by almost 50%, falling short of estimates.
• Ducommun Inc. (NYSE: DCO) received an analyst's downgrade after its Q4 earnings release.
• Gap Inc. (NYSE: GPS) said Q4 earnings fell due to weakness at Gap and Old Navy stores.
• General Motors Corp. (NYSE: GM) worse-than-expected results prompted speculation about its survival.

Just last week, Hormel Foods Corporation (NYSE: HRL) surprised investors with stronger-than-expected first-quarter earnings. Sales during the period were boosted by healthy demand for the company's recession-friendly canned ham-like product, Spam. Today, it seems that Standard & Poor's is revealing its own soft spot for potted meat, announcing that HRL will join its storied S&P 500 Index as of the close of trading on March 3.

Hormel will replace American Capital Ltd. (NASDAQ: ACAS) in the closely watched broad-market index. The latter stock has given up nearly 96% of its value during the past year, and it's extending those losses today with a plunge of more than 16%.

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

• Apollo Group Inc. (NASDAQ: APOL) reported that Q4 revenue soared despite the recession.
• Baidu Inc. (NASDAQ: BIDU) posted strong annual revenue, but at a slowing growth rate.
• Career Education Corp. (NASDAQ: CECO) easily topped Q4 earnings expectations, lifting shares up.
• Comcast Corp. (NASDAQ: CMCSA) Q4 earnings beat expectations and it increased its dividend.
• CVS Caremark Corp. (NYSE: CVS) shares jumped after it reported higher earnings in Q4.
• Digital River Inc. (NASDAQ: DRIV) shares soared on better-than-expected Q4 earnings and revenue.
• Expedia Inc. (NASDAQ: EXPE) reported dismal results due to a huge good will write down.
• Goodyear Tire & Rubber Co. (NYSE: GT) posted a greater-than-expected Q4 net loss and announced job cuts.
• Hormel Foods Corp. (NYSE: HRL) exceeded Q1 earnings expectations due to the popularity of SPAM.

Shares of Hormel Foods Corporation (NYSE: HRL) are on the upswing today, after the packaged-foods firm exceeded analysts' first-quarter earnings expectations. The company's upside surprise is partially attributable to strong sales of its infamous canned meat, Spam, which successfully lured in cost-conscious consumers.

During the recently concluded quarter, HRL banked a profit of $81.4 million, or 60 cents per share. That's an 8% slide from the same quarter last year, but analysts were expecting a profit of just 51 cents per share. Net sales rose 4% to $1.69 billion, with strong results for Dinty Moore stews, Hormel chili, and the aforementioned Spam.

Among all the negative economic data that came out last week was a positive surprise: retail sales were higher in January. A fluke or a glimmer at the end of the tunnel? That may depend on whether we see any positive surprises arising from items on this week's economic calendar:

• Consumer Analyst Group of New York Conference: Monday through Friday
• NY Empire Manufacturing Index (Feb. 2009): Tuesday, 8:30 AM
• NAHB Housing Market Index (Feb. 2009): Tuesday, 1:00 PM
• Fed's Bullard speaks before National Association of Business Economists: Tuesday, 1:00 PM

We don't expect to find investment advice from opinion columns, but New York Times columnist Frank Rich unleashed a quartet to those willing to read between the lines in his recent piece "Herbert Hoover Lives."

Here's the money quote (no pun intended) from the theater critic turned political pundit: "What are Americans still buying? Big Macs, Campbell's soup, Hershey's chocolate and Spam -- the four food groups of the apocalypse."

Last week, Bank of Montreal (NYSE: BMO), one of Canada's oldest and largest banks, reported growth in its fiscal fourth-quarter earnings. But it may be the only one that does, as at least two of the Canadian banks scheduled to report fourth-quarter numbers this week have already released preliminary results that warn of lower earnings due to debt write-downs and trading losses.

Analysts surveyed by Thomson Reuters expect Toronto-based Canadian Imperial Bank of Commerce (NYSE: CM) to post earnings 42.6% lower than a year ago, or $1.28 per share. CIBC beat estimates by a penny in the third quarter, but missed by a penny in the period before that. The bank faces a class-action lawsuit related to investments in collateralized debt obligations consisting of U.S. subprime mortgages. Shares have climbed 20.7% from a recent 52-week low of $39.52, but are down 37.8% in the past three months.

Toronto Dominion Bank (NYSE: TD), Bank of Nova Scotia (NYSE: BNS), and Royal Bank of Canada (NYSE: RY) are expected to report more modest earnings declines of $1.01 per share, $0.73 per share, and $0.83 per share, respectively. All three Toronto-based banks topped estimates in the third quarter. Toronto Dominion and RBC have recently announced plans to offer shares in order to raise capital. Toronto Dominion and Scotiabank have been trading near 52-week lows, and their share prices are down around 39% in the past three months. But only Toronto Dominion has a consensus buy recommendation from analysts.

The earnings season is beginning to wind down as we have passed the halfway mark of the quarter and the holiday season begins in earnest next week with Thanksgiving in the United States.

Bermuda-based Frontline Ltd. (NYSE: FRO) is anticipated by analysts surveyed by Thomson Reuters to be one of the biggest earnings gainers among companies scheduled to report quarterly results this coming week. The oil tanker fleet operator is expected to post third-quarter earnings of $1.97 per share, 86.8% higher than in the same period a year ago, on revenues of $399.5 million (+44.6%). Frontline missed estimates by 6.4% in the previous quarter, and the consensus recommendation by analysts is to hold FRO. While Motley Fool likes its robust dividend, Jim Cramer said in a recent Lightning Round that he prefers rival Nordic American Tanker Shipping Ltd. (NYSE: NAT). Shares have fallen 52.9% in the past three months, and reached a 52-week low of $25.00 on Friday.

Analog Devices Inc. (NYSE: ADI) is also expected to be among the week's biggest earnings gainers. Analysts are looking for the semiconductor chip maker to report a fiscal fourth-quarter profit of $0.44 per share, 31.8% higher than a year ago, on revenues of $661.7 million (+2.0%). Analog Devices has beat estimates in three of the past five quarters, but only missed by 1.3% in the previous quarter. Analysts on average recommend buying ADI, which has a forecast long-term EPS growth rate of 17.3%, which better than the S&P 500 and that of rival Texas Instruments Inc. (NYSE: TXN). Shares sank to a multiyear low of $16.23 on Friday, and are down 41.1% in the past three months.
