Shawkat Hammoudeh, professor of economics and international business at Drexel University's LeBow College of Business, says the perception is that even though U.S. unemployment reached 9.4 percent in May and home values remain depressed, there are rumblings of a recovery. "The oil prices are getting clues from the stock market about recovery, and the stock market usually predicts recovery within five months," Hammoudeh said. "According to the stock market, we should have a recovery starting in September."
