Asian markets tumble

Asian markets tumbled Monday despite recent news that two of the region's biggest economies, Hong Kong and Japan, have emerged from recession. The Nikkei fell 3.1 percent, to 10,268.61 despite Japan's announcement that its economy has enjoyed positive GDP growth for the first time in five quarters.

Hong Kong's Hang Seng ended the day at 20,137.65, clocking a 3.62 percent decline, and the S&P/ASX closed down 1.63 percent at 4,338.4. China's Shanghai Composite Index plummeted 5.8 percent – its biggest drop since November 18.
