The U.S. stock market closed higher across all three major indices, driven by semiconductor-led tech stock buying and a decline in international oil prices.

On July 10 (Korean time; July 9 local time), the Dow Jones Industrial Average closed at 52,487.41 on the New York Stock Exchange, up 139.02 points (0.27%) from the previous trading day. The Standard & Poor's (S&P) 500 index rose 60.93 points (0.81%) to 7,543.64, while the Nasdaq Composite surged 336.24 points (1.30%) to finish trading at 26,206.89.

Despite lingering caution due to U.S.-Iran tensions on the day, strength in the semiconductor sector led the broader indices. Renewed expectations for expanded investment in artificial intelligence (AI) infrastructure and data centers drew capital into tech stocks, with semiconductor-related names leading the Nasdaq's rally.

The decline in international oil prices also contributed to improving investor sentiment. While Middle East uncertainty remains a concern, easing oil price pressures somewhat alleviated inflation worries, boosting risk appetite.

The prevailing analysis in the market is that while geopolitical tensions are unlikely to be resolved immediately, growth expectations for semiconductors and large-cap tech stocks are supporting the market's floor.

Key variables for the future direction of the U.S. stock market include the level of U.S.-Iran tensions, oil price trends, and the Federal Reserve's interest rate policy direction.
