Lists of '07's worst stocks are filled with home builders, mortgage lenders and other financials who have gotten hammered with the subprime/housing bubble/credit crisis. The Inquirer/Bloomberg Philadelphia Index is no different. But just because a stock is a mutt one year doesn't mean it can't become a show dog the next. Case in point: SunCom Wireless Inc., this year's best-performing local stock. In 2006, SunCom shares lost 75 percent of their value. That year, the Berwyn company had posted widening losses, CEO Michael Kalogris was severely injured in a car crash, and its shares were delisted by the New York Stock Exchange. The wireless service provider's finances improved in 2007, but the stock popped in September, thanks to a buyout launched by T-Mobile.
