The Nasdaq set another all-time high. While buying continued centered on artificial intelligence (AI)-related tech stocks, the Dow Jones Industrial Average and the S&P 500 weakened, leaving the three major indexes mixed. This reflects the New York stock market as of the morning of the 23rd, Korea time.

[Closing figures by index on the 22nd (local time)] • Nasdaq Composite: Closed at 27,244.28, up 122.18 points (0.45%) from the previous trading day, an all-time closing high • S&P 500: Closed essentially flat at 7,764.64, down 0.06 points • Dow Jones Industrial Average: Fell 185.14 points (0.36%) to 51,863.69 • Russell 2000: Rose 14.56 points (0.5%) to 2,889.92

The Nasdaq extended its gains after surging 2.26% the previous day to set a record.

AI semiconductor stocks lead the rally

AI was once again the market's core axis. Semiconductor stocks tied to AI, including Micron, helped power the Nasdaq's rise. Reuters reported that tech stocks have re-emerged as the market's center as AI demand remains unbroken and corporate earnings stay solid.

'AII bubble' debate intensifies

However, debate over AI is growing even louder within the U.S. market. One side argues that expanding AI adoption, monetization, and massive capital spending on data centers and semiconductors will underpin tech stock earnings. The other side remains cautious, questioning how quickly the high valuations of AI companies and enormous investment costs can translate into actual profits. Recently, the so-called 'AI bubble' debate over whether AI investment has overheated has become a major market talking point.

Views within American society on AI technology itself are also divided. A Reuters/Ipsos poll found that 73% of U.S. adults worry that AI companies are not taking sufficient precautions to prevent serious harm. Beyond expectations for AI's economic and scientific potential, debates over safety and regulation are unfolding alongside the stock market's AI investment fervor.

Middle East situation and oil prices also factors

The Middle East situation was another variable for the market. U.S. President Donald Trump characterized his talks with the Iranian side as productive and mentioned the possibility of further negotiations. International oil prices coming off recent highs, easing some concerns about inflation and corporate costs, also influenced market sentiment.

Ultimately, the New York market on the day showed funds tilting back toward tech stocks as expectations and caution over AI clashed. While the Nasdaq set consecutive records, the Dow and S&P 500 failed to keep pace, highlighting selective movement centered on AI and semiconductors rather than a broad-based market rally.
