The stock market has gone up so far this week, despite the news out of the Middle East that ought to be roiling markets. Maybe we have McDonald’s to thank? I noted on the 3WHH podcast a couple weeks back that McDonald’s stock has slumped about 20 percent over the last couple months. Suddenly, to the cheers of John Yoo, McDonald’s has brought back the McRibb. (Which, if you listened to last week’s podcast, is called here in Hungary “Pig McFarm.”) Guess what: The market does better when McRibb is on the menu.
