AlQa'dah 12, 1436, Aug 27, 2015, SPA -- China stocks rebounded sharply on Thursday, snapping a savage five-day losing streak, as a rally on Wall Street brought some calm to shaky global markets, Reuters reported. Local and foreign investors hunted for bargains after a more than 20 percent plunge in the country's major indexes over the past week. But traders said the market remained vulnerable to sudden selloffs, as investors who bought shares using margin financing continue to deleverage, and as China's economic outlook remains weak. The blue-chip CSI300 index jumped 6 percent to 3,205.64, while the Shanghai Composite Index gained 5.4 percent, to 3,083.59 points. Both indexes posted their biggest one-day percentage gains in nearly two months. The Shanghai market currently trades at 14 times companies' earnings, compared with 22 at the market's peak in June.
