On the 27th, the KOSPI fell more than 3%, dropping below the 5,300 mark.

As of 9:26 a.m., the KOSPI was trading at 5,257.55, down 202.91 points (3.72%) from the previous session. The index opened at 5,300.61, down 159.85 points (2.93%), and has been extending losses.

As Google unveiled its ‘TurboQuant’ technology, which reduces AI memory usage to one-sixth, semiconductor stocks such as Samsung Electronics and SK hynix have continued to decline.

The KOSDAQ opened at 1,119.77, down 1.48% from the previous session.

Han Ji-Young, an analyst at Kiwoom Securities, said, “Today, the domestic stock market is also likely to face a tough start due to the sharp drop in U.S. equities, which were hit by a triple blow of Middle East war uncertainty, a surge in interest rates, and the TurboQuant incident.” He added, “However, another TACO (TACO·Trump always chickens out) remark by U.S. President Donald Trump after the close, together with a perception that the decline has been excessive given the plunge the previous day and the successive price corrections since March, will provide downside rigidity that helps curb a steep intraday fall in the index.”

The won-dollar exchange rate opened at 1,508.6 won, up 1.6 won from the previous session.
