Foreign investors snapped up W197 billion (US$1=W1,167) worth of stocks on the Korean stock market on Wednesday, matching the record of 34 days of consecutive purchases by foreigners.
The record was set in early 1998, just after Asian financial crisis.
The Korea Composite Stock Price Index rose to 2,049 points at one point in trading to reach a new high for the year. But investor jitters over the looming deadline for U.S. debt ceiling negotiations caused the KOSPI to close down 0.3 percent at 2,034.
Continued buying by foreigners is buoying up the won, which closed at W1,065.5 against the dollar, up W1.3 from the previous day.
