China’s stocks fell the most in six months following news of reduced foreign investment and increased economic concerns, Bloomberg reported. The Shanghai Composite Index tumbled 1.8% as the value of shares traded jumped to the highest since Nov. 12, 2010. Economists at banks cut their 2014 expansion forecasts after the weekend data and said they anticipate the government will step up the rollout of measures to support the economy. Authorities yesterday also approved 11 more initial public offerings. “August data is far worse than expected and with the new IPOs there’s renewed fears about liquidity,” said Zhang Haidong, analyst at Tebon Securities in Shanghai.
