BEIJING, Feb. 23 -- New share issue alerts have struck terror in the hearts of investors, sending the Shanghai lead indicator down 3.47 percent on Friday, the largest one-day drop this month. The benchmark Shanghai Composite Index shed 156.89 points to close at 4370.29, with 679 out of 910 stocks closing lower. The Shenzhen Component Index tumbled 3.72 percent to close at 16179.52.
