TMTPOST -- South Korea's currency and stock market pulled back from early gains after a vote to impeach President Yoon Suk Yeol, as investors shifted their attention from political developments to ongoing economic concerns. The Korean won and the benchmark Kospi Index fluctuated between gains and losses in mid-morning trading, reversing the initial rally sparked by Yoon's impeachment. The president had shocked investors on December 3 by declaring — and quickly reversing — martial law, leading to a widespread selloff of Korean assets. The short-lived market boost was largely attributed to traders already factoring in the impeachment, according to analysts. “Nothing has changed fundamentally,” said Cho Junkee, an analyst at SK Securities Co. “The market had already priced in the impeachment last week, and the vote is not providing further upside as investors take profits.” The Kospi Index had risen as much as 0.9% in early trading, approaching a recovery of all losses since the martial law announcement. However, the index is now flat for the day, while the smaller Kosdaq Index has gained around 0.8%. Similarly, the South Korean won has erased its earlier gains, now trading lower against the dollar at 1,437.55, after rising as much as 0.5% following the impeachment vote.
