NEW YORK ( TheStreet) -- With weak third-quarter results coming out from Yum! Brands ( YUM) and Coca-Cola ( KO), McDonald's ( MCD) investors are chewing their nails, anxiously anticipating what the fast-food giant will say on Monday. I wouldn't put too much emphasis on the company's quarter-to-quarter performance though.First and foremost, the struggles of the entire consumer discretionary space are nothing new. Even the so-called "recession-proof" stocks like Wal-Mart ( WMT) have been hurt by weak same-store sales and reduced traffic. I don't believe there has been anything to suggest that these concerns will be immediately reversed as a result of the recent government shutdown. For McDonald's, whose Golden Arches have long been the gold standard in the U.S. quick-service space, weak margins and sluggishness in China have taken a toll on the company's recent performance.
Now I'm making this comparison knowing full well that Yum! has had some extraordinary circumstances in China, including scandals regarding two suppliers to its KFC restaurants and fears over the health of its chickens. So it's not exactly an apples-to-apples comparison with McDonald's. That said, it's worth noting that in the July quarter, both companies posted 1% growth in same-store sales, the metric tracking performances of restaurants opened for at least one year. Not only that, both companies have trended comparably in their strengths and weaknesses, including posting similar 1% growth in the U.S. All this while both companies suffered weak revenue results internationally. It's foolish to put too much emphasis on one quarter with McDonald's, especially given the company's size and scale. Besides, as one of the largest franchisers in the world, revenue growth alone is not always an accurate gauge of the company's true performance.
