Overnight, US stocks also performed weakly. The S&P 500 Index fell 0.06% to close at 7,753.10 points; the Dow Jones Industrial Average fell 0.11% to 53,975.98 points; and the Nasdaq Composite Index fell 0.32% to 26,605.36 points. A lack of clear upward momentum in US tech stocks also put some pressure on the Asian semiconductor sector.

On the news front, the South Korean government further ramped up support for the semiconductor industry, announcing the establishment of a special semiconductor fund worth 5 trillion won and introducing a series of supporting policies to accelerate the implementation of the semiconductor "mega-project" totaling over 576 trillion won. As demand for AI chips continues to grow, South Korea is strengthening the competitiveness of its domestic semiconductor supply chain by expanding policy support and industrial investment.

On the geopolitical front, significant uncertainty remains in the Middle East. US President Trump demanded that Iran pay related compensation and stated that this demand would be included in future negotiations, while claiming that the US military has "100% control" over the Strait of Hormuz. On the Iranian side, intensive military personnel reshuffles occurred, with the Supreme Leader appointing six senior military commanders. The market continues to watch whether US-Iran tensions will further affect energy supplies and the performance of global risk assets.
