NEW YORK — U.S. stock indexes continued to trade near record levels this week despite sharp swings in technology shares, as investors balanced enthusiasm over artificial intelligence-related growth with concerns about valuations, interest rates and broader market conditions.
The Dow Jones Industrial Average reached fresh record highs on Tuesday, while the benchmark S&P 500 remained near historic peaks. The Nasdaq Composite, which is heavily weighted toward technology companies, fluctuated after recent gains, reflecting volatility in major AI-linked stocks and semiconductor companies. Reuters reported that the Dow recorded its second consecutive record close on June 16 even as the S&P 500 and Nasdaq ended lower.
Technology shares have been a primary driver of the market's advance in 2026. Investor demand for companies involved in artificial intelligence infrastructure, cloud computing and semiconductor manufacturing helped push both the S&P 500 and Nasdaq to record closing highs in late May. Reuters reported that AI-related optimism and strong earnings expectations supported gains across the sector, with chipmakers among the strongest performers.
Earlier this month, Hewlett Packard Enterprise posted results that exceeded analyst expectations and accelerated its long-term financial targets, contributing to renewed confidence in AI-related spending. Alphabet also announced plans to raise capital for AI infrastructure investments, underscoring the scale of spending by major technology companies. Reuters reported that those developments helped lift the Dow and S&P 500 to fresh records on June 2.
At the same time, technology stocks have experienced periods of pronounced volatility. On June 10, the Nasdaq and S&P 500 fell to their lowest levels in more than a month as investors reassessed valuations in the semiconductor sector and reacted to weaker sentiment surrounding some AI-related companies. Reuters reported that major chipmakers, including Nvidia, Broadcom and Micron, came under pressure during the selloff.
Market participants have also been watching monetary policy developments. On Wednesday, the Federal Reserve left interest rates unchanged but signaled that inflation risks remain under review. Following the announcement, the Nasdaq and S&P 500 edged lower while investors evaluated future policy guidance from Federal Reserve Chair Kevin Warsh.
“The earnings have been constantly revised upwards,” strategist Frank Benzimra of Société Générale told Reuters this month, referring to expectations for large technology companies and other market leaders. The comment reflected continued investor focus on corporate profitability and AI-related growth prospects.
As of Wednesday, major U.S. indexes remained close to record territory. Investors continued to monitor economic data, Federal Reserve policy and developments in the technology sector, with AI-related companies remaining among the most closely watched stocks on Wall Street.
