I'm going to take a brief look at two stocks that traded on Friday based on earnings reports. Both can be found in the foodstuffs industry. And both beat Wall Street's projections. But which one do I prefer?

Hormel Foods (HRL), the company behind the Spam and Dinty Moore brands, made 63 cents per share in the fiscal third quarter, which, according to Reuters, was three pennies ahead of the estimate. But the good news doesn't stop there: guidance for the full fiscal year was increased.

With current tough times, and maybe getting tougher with deflation as a real possibility, investors who think more defensively may see better returns with more conservative stocks, ones with dividends and solid balance sheets. Now isn't the time to be too aggressive. With that in mind, here are five stocks that made our column dedicated to conservative investors.

Avista Corp. (AVA): an energy company, engaged in the generation, transmission, and distribution of energy and energy-related businesses in the United States and Canada. The company operates through two segments, Avista Utilities and Advantage IQ.

Below are some highlights from this past week's earnings coverage on BloggingStocks. Click through to the original posts for more details.

• Applied Materials Inc. (AMAT) swung from a year-ago loss to a Q2 profit that was better than expected.

• Gap Inc. (GPS) said its higher Q1 earnings beat expectations while revenue fell in line with estimates.

Here's a weird one. You would think, considering all the scary volatility going on in the markets right now, that a stock like Hormel Foods (HRL) would be trading higher today. Investors would theoretically want to get defensive and hedge themselves against all the bearish sentiment with an equity based on something everyone needs to do: eat!

But it's not working that way this afternoon. Hormel is down $1.19, or nearly 2.9%, to $40.59 on decent volume. Traders apparently were not impressed with the second-quarter earnings report.

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

• Abercrombie & Fitch Co. (ANF) lower Q4 earnings topped estimates and same-store sales also declined.
• Campbell Soup Co. (CPB) reaffirmed its earnings outlook but lowered its revenue forecast for the full year.
• Daimler AG (DAI) provided guidance for the year that included slashing its dividend, sending shares lower.
• Dell Inc. (DELL) lower Q4 earnings beat estimates by a penny but it didn't offer guidance, sending shares lower.
• Goodyear Tire & Rubber Co. (GT) easily topped Q4 earnings estimates and revenue increased as well.

Hormel Foods (HRL) surged past analysts' fiscal first-quarter earnings estimates, with the sultan of Spam swinging to a profit of $111.2 million, or 82 cents per share, up 37% from the year-ago period. Sales for the quarter climbed 2.3% to $1.73 billion. Both numbers easily exceeded Wall Street's consensus expectations, which called for a profit of just 68 cents per share on $1.67 billion in revenue.

Hormel added to the positive momentum by boosting its earnings forecast for the rest of fiscal 2010. The packaged-foods firm now expects to bank a profit of $2.68 to $2.78 per share, up from its prior forecast of $2.63 to $2.73 per share.

As so often happens at this point in the earnings season, focus begins to shift to the results from retailers. And the world's largest retailer is among those that step into the spot light this week.

Analysts surveyed by Thomson Reuters are looking for Wal-Mart Stores Inc. (WMT), which was aggressively competitive during the holiday shopping season and also recently announced a new global strategy, to report fourth-quarter earnings of $1.12 per share, up from $1.03 per share in the year-ago period. Revenue for the three months that ended in January is expected to have risen 4.9% to $114.5 billion. The full-year forecast calls for earnings of $3.61 per share (+5.3%) on $409.1 billion in revenue (+0.9%). Walmart has not missed earnings estimates in the past five quarters.

Most investors spend a lot of time analyzing P/E ratios, PEG ratios, ROIC, ROE, gross margins, insider trading, and Beta.

But might the path to profits come instead from looking for companies that have wellness programs for their workers? The 2009/2010 North American Staying@Work Report: The Health and Productivity Advantage from Watson Wyatt Worldwide says yes.

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.
