It appears that Wendy's/Arby's (WEN) is about to have a roast beef sale. The company announced this morning that it is considering selling the struggling Arby's chain in order to focus more on the Wendy's hamburger chain.

Both sides of the company's eateries, Wendy's and Arby's, have seen sales slump, but Arby's has had the most problems thanks mainly to sandwiches that can cost more than five bucks. With such a price tag , those sandwiches weren't selling wel in the current economic atmosphere.

Wendy's/Arby's Group (WEN) was wallowing in red ink Friday morning, after the fast-food firm confessed to a third-quarter loss and warned that its full-year earnings would arrive at the low end of its previously forecast range. Even more troubling, the restaurateur said it's not yet prepared to offer financial guidance for 2011.

For the recently concluded quarter, Wendy's swallowed a net loss of $900,000 -- which translates to a negligible per-share deficit -- down from its year-ago profit of $14.69 million, or 3 cents per share. Revenue for the period slipped 4.7% to $861.2 million. Analysts surveyed by Thomson Reuters were anticipating a profit of 4 cents per share on $882.6 million in revenue.

Yum! Brands (YUM), a restaurant entity whose multiple concepts compete with McDonald's (MCD) and Wendy's/Arby's Group (WEN), gave shareholders some great news this week: their dividend is going up! According to the press release, the quarterly payment is now 19% higher, coming in at 25 cents per share.

Not bad at all. Looks like management is feeling good about future cash flows. As we all know, dividend increases can be indicative of fundamental fiscal strength. And I like it when a dividend is backed by a strong portfolio that is well-recognized by consumers. Establishments like KFC and Taco Bell are strong trademarks.

Burger King (BKC) really laid a whopper Tuesday when it announced weaker-than-expected earnings.

Burger King said net income fell to $49 million, or 36 cents a share, during its fiscal fourth quarter, compared to $58.9 million, or 44 cents a share, a year earlier.

It looks like Burger King's successful attempt to court young males with its brash commercials and willingness to indulge a less-than-healthy appetite has hurt the company during the recession -- as this demographic has been disproportionately hit with job losses in construction and manufacturing.

Wendy's/Arby's Group (WEN) issued its second-quarter earnings on Thursday. The fast-food entity beat expectations. But, as far as I'm concerned, it wasn't any big deal. In fact, the market sort of agreed with me. By the end of the trading session, shares were off by a mere penny, settling out at a price of $4.14. Volume wasn't that interesting, either.

According to Briefing.com, net profit of 6 cents per share went beyond the estimate by a penny. However, same-store sales at both the Wendy's and Arby's declined. System-wide comps in North America contracted 1.7% for the former and 7.4% for the latter.

McDonald's Corporation (MCD) was down roughly 2% as I began composing this piece during the afternoon session. I hope investors weren't paying attention to the bears who were in control of the fast-food giant's shares. To me, the stock seems to be in good shape, and in the kind of trading climate we're in, it could be a useful instrument for the cautious player.

I'm seeing a quote of around $70 go by on my screen. Not bad in the least, considering that the 52-week high is $71.84. It shows the kind of resilience the stock possesses. Indeed, considering how many equities have pulled back from their 52-week highs, you've got to enjoy this element of the story.

I'm not a fan of Wendy's/Arby's Group (WEN). It just doesn't seem as safe as stocks like Burger King (BKC), McDonald's (MCD), or Yum! Brands (YUM). Of course, I'm certain I did nothing more than state the obvious.

As a low-priced equity, Wendy's/Arby's Group always possesses the risk of volatility. Today, the shares are off by over 3% in afternoon trading; at the time of this writing, I saw a share price of $4.93. Hey, it's better than the day low of $4.86. The company had reported earnings results for the first quarter Thursday morning. Do the numbers make the company look more or less attractive?

Burger King (BKC) is turning up the heat in its war with McDonalds (MCD) for early morning sales. In selected markets, Burger King is advertising the availability of a "Burger King brunch" in a quest to cash in on lucrative morning sales. This is only a few months after announcing Burger King will carry coffee made by Starbucks to provide a more flavorful alternative to its BK Joe coffee.

This is what the fast-food breakfast wars have become: Mimosas at the drive-thru window.
