SEOUL, May 27 (AJP) - South Korea’s main bourse briefly halted Wednesday after the benchmark index tracking the top 200 listed companies surged 5 percent, propelling the KOSPI past the 8,400 mark just a day after breaking into unprecedented four-digit territory.

As of 9:30 a.m., the KOSPI had risen 3.63 percent to 8,355.81 after briefly testing above 8,400 shortly after the opening bell, as memory chip giants continued to shatter record highs.

Samsung Electronics surged more than 6 percent to 318,000 won, while SK hynix jumped more than 9 percent to 2.24 million won on strong institutional and foreign buying.

The KOSDAQ, however, fell 1.52 percent, to 1,154.68.
