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:

• Best Buy Inc. (NYSE: BBY) was downgraded by one analyst ahead of next week's Q2 earnings report.
• Campbell Soup Co. (NYSE: CPB) better-than-expected Q4 and full-year profit failed to impact the share price.
• FedEx Corp. (NYSE: FDX) boosted its Q1 earnings guidance ahead of next week's quarterly report.
• JoS. A. Bank Clothiers Inc. (NASDAQ: JOSB) saw its Q2 earnings jump higher than expected.
• Korn/Ferry International (NYSE: KFY) swung to a Q1 net loss as revenue plunged despite cost cuts.
• lululemon athletica inc. (NASDAQ: LULU) strong Q2 numbers topped estimates and drove shares higher.

Pork producer Smithfield Foods (NYSE: SFD) confessed Tuesday morning to a first-quarter loss of $107.7 million, or 75 cents per share, notably worse than its year-ago loss of just $13.2 million, or 10 cents per share. Excluding one-time charges, SFD would have swallowed a loss of 56 cents per share for the recently concluded quarter. Revenue for the period fell by more than 13% to $2.72 billion.

Both figures fell short of analysts' expectations, which called for a loss of 53 cents per share on $2.82 billion in revenue. Thanks to the twin factors of the recession and the still-spreading H1N1 virus -- a.k.a. the "swine flu" -- Chief Executive Larry Pope said, "I feel like the world has been against us for 12 months." (While H1N1 cannot be contracted by consuming pork products, the pork industry has suffered nevertheless by association.)

Investors and analysts may be wondering whether the market rally is really over, and whether this signals more trouble ahead for the economy. Well, the Federal Reserve is scheduled to release its next Beige Book report of economic conditions on Wednesday, offering a glimpse of where things stand. The Beige Book report in July suggested that, in some of the 12 Fed districts, the economy appeared to be stabilizing, suggesting that the recession may have reached its bottom, but offering little sign of a recovery. Retail activity remained weak and employment numbers were not good. Yet the minutes of the FOMC August meeting seemed a bit more optimistic about the economy.

In addition to the Beige Book report, the TIPP Economic Optimism Index is scheduled to be released Tuesday, and the University of Michigan Consumer Sentiment Index comes out Friday. So by the end of the week, we could have a good gauge of the mood about the U.S. economy.

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.

Telmex (NYSE: TMX) is expected to report Q1 EPS today. TMX May option implied volatility of 43 is below its 26-week average of 50, according to Track Data, suggesting decreasing price movement.

It ran like this:

DJIA: 8,669.11 (down 2.97%)

NASDAQ: 1,547.43 (down 1.55%)

S&P 500: 887.23 (down 2.47%)

General Motors Corp. (NYSE: GM) lost some ground on fears of a delay in the proposed $15 billion Congressional bailout plan. After this gained so much yesterday, much of this was in the news already.

Merck & Co. Inc. (NYSE: MRK) traded down after its annual pipeline review. The event included formal guidance out of the company on its drug pipeline for the next year and general commentary about how many drugs are in the pipeline for 2010 to 2012. Financial guidance did not seem to impress the market.

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.
