It’s not just temperatures that are climbing this summer. The Korean stock market is also hot as it continues to break records left and right. On Thursday, the main index, the Kospi, reached a new high and so did Korea’s largest conglomerate, Samsung Electronics. The bullish rally occurred despite the continued saber rattling of North Korea. Foreign investors appear to be unfazed by the geopolitical tension, as their market capitalization has reached the highest level ever. The Kospi closed on Thursday at 2,409.49, up 17.72 points or 0.74 percent from the previous trading day. This is the first time the Kospi has broken past 2,400 and comes less than two months after it passed the 2,300 barrier. The market started the day on a positive note, taking only a minute after opening to break past 2,400. In that time, the index rose 14.26 points from the previous session, and during the day, the market even gained as much as 30 points, but last-minute selling limited the Kospi from making further advances. This upbeat performance was triggered by strong buying from institutional investors, and foreign investors further fueled the favorable upswing. The Kospi also got a boost from U.S. Federal Reserve Chair Janet Yellen’s overnight comments in Washington that current economic growth in the United States warrants a “gradual increase in the federal funds rates over time.”
