While the deflationary times that we are seeing has been helping McDonald's over the past year, another big reason why the company was able to do so well in 2007 was the weak dollar which helped its overseas business. McDonald's is as popular overseas as it is here in America, and around 43% of its total revenues come from Europe and the U.K., where the euro and the British pound were strong against the dollar during the first part of 2008. That is not so much the case these days, and as the dollar strengthens, McDonald's overseas revenues will start to shrink.

The company has stated that 10% drops in these foreign currencies could relate to an 8 or 9 cent difference in the company's bottom line. It will be interesting to hear how the strengthening dollar has impacted the company. The dollar is expected to remain strong against these currencies through 2009 as Europe continues to deal with its own deepening recession.

Overall, I expect to see another good quarter from the company, with the only possible weakness at this point being its overseas revenues. On Monday morning, we will see just how hard the company was hit by the rising dollar. The last time that the company was not able to at least match analysts estimates was all the way back in January 2005 when it missed its fourth quarter '04 number. Will it continue its strong run, or is the stock poised to tumble? We will find out on Monday.

Here is a chart of the stock to illustrate just how well it has done over the past 12 months:
