South Korea’s KOSPI opened the week sitting just above its record close, after Friday’s 2.31% surge left it at 5,808.53. The KOSDAQ, however, edged down 0.58% to 1,154.00, as strong chip and defense names managed to offset pressure from weaker growth stocks.
The record-setting rally stands on just two uncertain pillars: chips and policy optimism. “Investors have maintained expectations” for shareholder-friendly moves, said Kim Seok-hwan at Mirae Asset Securities, but he warned, “the risk of a full-scale conflict is not negligible.” Iran headlines, he added, continue to keep nerves stretched for some.

Positioning jitters are surfacing. The KOSPI200 volatility index (VKOSPI), a barometer for investor anxiety, settled at 43.87 on Friday.

The record run could unravel quickly. Any slip in global AI earnings, a spike in oil prices tied to geopolitics, or fresh dollar strength—any of those might prompt profit-taking in Seoul. Not much cushion left after such a stretch of gains.
The rally isn’t just about chip stocks—the move has been wide enough to catch plenty of attention across the board. As of Friday’s close, the KOSPI was up 5.48% over five days, a run that’s lured fresh short-term cash and set the stage for sharper reactions if policy or earnings news hits.
