AlQa'dah 03, 1436, August 18, 2015, SPA --The Shanghai share index plunged more than 6 percent Tuesday, its biggest drop in three weeks, as investors resumed sell-offs of Chinese stocks despite the stabilization of the Chinese yuan after a sharp devaluation last week, AP reported. Other Asian stock markets also turned lower in afternoon trade. The Shanghai Composite Index fell 6.2 percent to 3,748.16, its largest drop since the index's 8.5 percent dive on July 27, its biggest slide in eight years.
