Shanghai, CHINA: Chinese investors arrive at the Shanghai Stock Exchange as they pass near a blossom tree containing traditional red envelopes containing money for good luck in Shanghai 28 February 2007. The dramatic one-day wobble in Chinese share prices highlights the tricky task facing regulators as they try to prevent a dangerous bubble in a market that has grown 130 percent in a year. Analysts said that the 27 February 8.84-percent plunge in the Shanghai Composite Index suggested the government may have miscalculated, the sell-off was also partly caused by profit taking after a long period of gains.
