U.S. stocks closed sharply lower Friday, with the Dow Jones Industrial Average tumbling as much as 357 points, amid jitters over Greece's debt crisis and concerns over regulations in China. Investors also weighed the strengthening dollar's drag on corporate profits during earnings season. Meanwhile, China's regulators tightened rules on margin lending, cracking down on over-the-counter margin trading and regulations that allow fund managers to lend shares for short-selling.
