U.S. stock markets ended Wednesday's session with mixed results in early July trading. The Dow Jones Industrial Average climbed to a new all-time high, extending its strong first-half performance, while the tech-heavy Nasdaq Composite Index faced pressure from declines in semiconductor stocks.

The Dow Jones Industrial Average rose 47.31 points, or 0.09%, to close at 52,366.51. The Nasdaq Composite fell 120.67 points, or 0.46%, to 26,093.05. The S&P 500 index declined by 3.46 points, or 0.05%, to finish at 7,495.90.

The Nasdaq Composite dropped approximately 0.4% as investors sold semiconductor shares, taking profits after the sector's collective surge of over 80% in the first half of 2026. Micron Technology shares plunged 9%, despite maintaining a year-to-date gain of roughly 250%. SanDisk shares fell 10%, showing a slowdown after skyrocketing more than 850% in the first six months. NVIDIA and Broadcom also saw declines of about 1% and 2%, respectively.

Jeff Kilburg, founder and CEO of KKM Financial, commented on the market rotation, stating, "The 'great rotation' trade continues into the third quarter, with unremarkable blue-chips in the Dow Jones continuing to attract inflows, funds that are coming directly from recent profit-taking in tech stocks. This is very healthy and highlights the broadening breadth of this ongoing bull market, now in its fourth year."

Major stock indices had a robust start to 2026. In the first six months of the year, the Dow gained 8.9%, marking its best first-half performance since 2021. The broader S&P 500 index advanced 9.6%, while the Nasdaq increased 12.8%. The small-cap Russell 2000 index surged nearly 22%, achieving its strongest first-half showing since 1991.

Gains in other major technology stocks helped limit the Nasdaq's losses. Shares of Meta Platforms, Inc. jumped nearly 10% after the company announced plans to launch a cloud business and sell excess computing power—a move that could boost its revenue. Mega-cap stocks Microsoft and Apple also posted significant gains of about 3% and 2%, respectively.

Traders were also monitoring commentary from the Federal Reserve. Chairman Kevin Warsh spoke at a European Central Bank conference in Portugal. While he did not provide specific monetary policy hints regarding the upcoming meeting later this month, he noted that "we have already seen prices are too high."
