South Korea's main stock index closed higher on Friday... after a turbulent morning session. The benchmark KOSPI closed at 21-56, up nearly Point-four percent from the previous session. But during morning trading, it hit the lowest point since last March... dropping at one point to 21-18...mainly due to sharp dips in the U.S. and Chinese stock markets. Analysts say the KOSPI's rebound followed a similar pattern in Beijing's stocks in the afternoon. Seoul's junior stock index, the tech heavy KOSDAQ, also closed higher with a one-and-a-quarter-percent gain.
