Stock Market Slightly Unchanged as AI Sector Drives Activity

The U.S. stock market showed minimal movement on Tuesday, with the Nasdaq Composite, Dow Jones Industrial Average, and S&P 500 remaining largely flat despite a strong rally in artificial intelligence (AI) stocks. The previous day's record high for the Nasdaq was followed by slight declines in futures trading. Optimism around AI development and falling oil prices contributed to market sentiment. Meta’s stock rose again after an 11% gain on Monday, driven by its new Muse AI app becoming a top download on the App Store. This signaled increased demand for chips used in AI infrastructure. The tech rally extended into Asian markets with gains reported in both the Nikkei and KOSPI indices. Investors are also watching upcoming economic data releases and earnings reports from KB Home and AutoZone, while geopolitical tensions remain a focus ahead of potential U.S.-Iran talks.
