As I mentioned yesterday (Thursday) in Part One of this story about Middle East investments , instability makes investing in this tumultuous region fairly tricky. But that doesn't mean you ought to avoid it entirely. After all, the International Monetary Fund (IMF) said in its World Economic Outlook that the region's economy would expand at a 5.1% pace in 2011, outpacing the United States and Europe. And contrary to the perception of many Westerners, that growth projection isn't based primarily on the price outlook for oil, which has trended higher for most of the past year. Rather, it's keyed to everything from construction and new-business development to banking, tourism and even Internet gaming.
