Woori Technology closed down more than 10% on the 2nd. The main factor is interpreted as a surge in profit-taking sell-offs, centered on nuclear power-related stocks, as geopolitical risks diminished with the military tension between the United States and Iran shifting into a ceasefire phase.

According to the Korea Exchange, Woori Technology closed at 11,250 won, down 1,300 won (10.36%) from the previous trading day. During the session, it fell to as low as 11,140 won, showing clear downward pressure.

Recently, domestic nuclear power stocks had maintained a strong trend as geopolitical uncertainty in the Middle East and energy security issues came to the forefront. However, as the U.S.-Iran military conflict took on the form of a ceasefire and tensions eased, profit-taking sell-offs rapidly expanded, centering on stocks that had surged in the short term.

On the same day, both the KOSPI and KOSDAQ fell in tandem in the domestic stock market, dampening investor sentiment. With the preference for risk assets weakening, selling pressure flowed into small- and mid-cap theme stocks overall, which is analyzed to have widened Woori Technology's decline as well.

The market views that the combination of burden from short-term gains and expectations for stabilization in the Middle East situation has increased volatility across nuclear power theme stocks overall.
