Stock markets go through many different cycles. In each one, there are one or two elements that make a successful investment. For example, interest rates are always a concern for financial institutions or companies that borrow a large amount of money. For these groups, the higher interest rates go, the lower profits will most likely be unless they are able to raise prices and/or cut costs faster than interest rates rise.

Right now, the main focus for most investors should be revenues. That's because without increasing revenues, there is an absolute amount of profits that any company can achieve. Simply by cutting costs, a company can increase profits, up to a point. But eventually lowering expenses isn't enough because there are only so many costs that can be cut before a product or service begins to weaken and affect sales.

Though the earnings season is winding down, and the coming week includes the Thanksgiving holiday in the U.S., plenty of reports are still due out. And analysts surveyed by Thomson Reuters don't seem to be expecting too many turkeys among this week's bunch.

Leading U.S. meat processor Tyson Foods Inc. (TSN), which has just named a new chief executive officer and a new chief operating officer, is expected to report fiscal fourth-quarter earnings of $0.26 per share, up from $0.14 in the same period of last year. But revenue is expected to total $6.9 billion, or 4.3% less than a year ago. The full-year forecast is for a profit of $0.25 per share (-16.7) on $26.4 billion (-3.9%) in sales. This dividend payer has offered upside surprises in the past two quarters, topping estimates by 11 cents per share in the third quarter.

Halloween, though not the blockbuster holiday that Christmas is, still results in some additional spending on the part of consumers as they stock up on candy and costumes, and maybe take in a scary movie or two. With those treats in mind here are some stocks that may give investors sweet dreams -- and hopefully not nightmares.

As is well known, candy is all the rage at Halloween, and among the largest candy stocks are Hershey Co. (NYSE: HSY) and Cadbury PLC (NYSE: CBY). Last week, Hershey reported third-quarter earnings rose 30% despite weaker volumes affected by higher prices for its sweets. Last year's numbers also included special charges. Still the company said it expects full-year earnings to be ahead of Wall Street forecasts. In 2010, the Pennsylvania company said it expects earnings excluding items to rise 6% to 8%. The stock has a forward-looking price-to-earnings ratio of 16 and a current dividend yield of 3.1%.

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?

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.

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."

Typically, when the economy enters a recession, companies that are in the consumer non-durable sector, i.e., consumer staples, see their stocks trade higher as money flows into bulletproof subsectors of the economy that don't suffer from spending cuts.

Companies like Proctor & Gamble (NYSE: PG), Heinz (NYSE: HNZ), Hormel (NYSE: HRL), Kraft (NYSE: KFT), General Mills (NYSE: GIS), Johnson & Johnson (NYSE: JNJ), Pepsi (NYSE: PEP), Coca-Cola (NYSE: KO), Campbell Soup (NYSE: CPB), Colgate-Palmolive (NYSE: CL) and even Berkshire Hathaway (NYSE: BRK.B), which was down a whopping 49% before getting a year-end bounce.

I think Warren needs to get off TV and get back to work.

My point here is that all of these fortress names got beat up to the tune of 30% to 50% when they were supposed to be the go-to names that would put in a stealth rally in a bear market.

Seems the kitchen and bathroom stocks didn't work this time around.
