South Korean shares rallied Thursday, extending a winning streak to a fourth consecutive session, thanks to ample economic rebound hopes in financial markets and better-than-expected quarterly earnings by leading stocks, Yonhap reported. The Korean won fell against the U.S. dollar. The benchmark Korea Composite Stock Price Index (KOSPI) rose 30.75 points, or 1.33 percent, to close at 2,342.61. The closing marks the highest since 2,343.07 points on Sept. 28, 2018.
