On Monday July 28, Kraft (NYSE: KFT) will be reporting its earnings results for the second quarter. Kraft is a well-known manufacturer of supermarket foodstuffs. We all know the brands: Oreo cookies, Nabisco, Oscar Meyer and many, many others.

It should be a defensive stock, just like Campbell Soup (NYSE: CPB) or PepsiCo (NYSE: PEP), right? Well, it is and it isn't. It's defensive in the sense that, as the cliche goes, people still want to eat their favorite foods even during recessionary times. It isn't in the sense that the stock is down by 16% (as of this writing) in the one-year time period. It does have a nice dividend yield, however, and Warren Buffet seems to like it.

What should investors be looking for on Monday? Well, they should definitely be looking at the margins. Is Kraft navigating this inflationary period in as efficient a manner as possible? I think Kraft will do OK in this regard. I'm not expecting any sort of wide expansion of gross margin, but I think management will report stability in this area.

Hershey (NYSE: HSY) , which recently reported numbers for its own quarter (see Brent Archer's idea for a trade involving Hershey options), did well in keeping margin-erosion at bay. Hershey also beat estimates by a penny. Considering that Kraft beat analyst estimates last quarter, that it has a good history of going beyond expectations and that Hershey was able to beat, then I would have to say that Kraft should have no problem beating on Monday. Hershey has had its share of troubles lately, keep in mind.

Before the market opens tomorrow morning, American auto maker Ford Motor (NYSE: F) will be reporting its second quarter numbers. Wall Street is not looking for a great quarter from the company.

Analysts on average expect the struggling auto maker to post a loss for the quarter of 25 cents per share, and revenues totaling $34.6 billion. The last time that the company reported earnings was back on April 24 when it shocked Wall Street with a 5 cents a share profit versus consensus estimate for a loss of 16 cents for its first quarter.

This quarter has proven to be tough for the company, which recently posted pretty bad June sales figures. In fact, sales for June declined by a devastating 28% compared to the same period last year.

McDonald's (NYSE: MCD), whose competitors include Yum! Brands (NYSE: YUM), Burger King (NYSE: BKC), and Wendy's (NYSE: WEN), isn't known for being a part of a healthy diet, no matter how much branding it's done in that area. However, it is known for delivering good earnings. That's why investors probably aren't too worried when it comes to Wednesday, the day that the fast-food behemoth is set to hand off a sack of quarterly numbers at the earnings-report drive-thru.

According to AOL Finance, McDonald's beat the street by a wide margin in the first quarter. The call was for about 70 cents per share which Mickey Dee's beat by a whopping 11 cents. The previous quarters weren't as impressive, but they were solid enough. McDonald's seems to have the game of at least matching expectations down pat, so I am confident that come Wednesday, the company's bottom line will be close to the 86 cents per share that Wall Street is looking for in the second quarter, according to Earnings.com.

If McDonald's makes the number, then it will represent growth of over 20%. Double-digit appreciation is a valuable commodity in this time period. I can't say, though, that McDonald's won't have its challenges cut out for it. After all, inflation is affecting everyone, and fuel prices theoretically could hamper the popularity of the company's valuable drive-thru asset (I used one last evening myself). But McDonald's has that famous dollar menu going for it, so even in tough times, fans of fatty foodstuffs can still afford the oily, heart-clogging grub.
