U.S. stocks finished mixed on Monday, June 8, as semiconductor shares rebounded sharply from last week’s selloff while a fragile Middle East ceasefire and rising Treasury yields kept pressure on parts of the broader market.
The Nasdaq Composite led the recovery, rising 0.86% to 25,929.66, driven largely by gains in semiconductor stocks. The S&P 500 added 0.30% to 7,405.73, while the Russell 2000 gained 0.85%. The Dow Jones Industrial Average slipped 80.77 points, or 0.16%, to 50,786.01.
The rebound followed Friday’s steep technology selloff, when investors pulled back from many of the market’s largest artificial intelligence-related stocks.
Geopolitical concerns remained in the background as a fragile ceasefire between the United States and Iran continued to hold despite reports of additional strikes involving Israeli and Iran-backed forces over the weekend. Oil prices were relatively stable, with U.S. crude remaining above $91 per barrel.
Meanwhile, the yield on the benchmark 10-year U.S. Treasury note climbed to approximately 4.56%, reflecting ongoing concerns that strong economic data could keep interest rates elevated longer than investors had expected.
One of the day’s most significant business developments came from Amazon, which announced a multibillion-dollar, multiyear agreement with Corning Incorporated to supply the optical fiber and cable needed to connect Amazon’s rapidly expanding U.S. data-center network.
The agreement is expected to create approximately 1,000 new manufacturing jobs at Corning facilities in North Carolina, along with hundreds of construction jobs tied to plant expansions. The companies also announced plans to expand a fiber-optic technician training partnership with Catawba Valley Community College, helping prepare workers for growing demand created by artificial intelligence infrastructure projects.
Investors welcomed the announcement. Corning shares surged roughly 8%, while Amazon gained about 1.2%.
The strongest gains, however, came from the semiconductor sector.
Micron Technology jumped nearly 10% after falling roughly 13% on Friday, recovering much of its recent decline. The rally was helped by a higher price target from Wells Fargo, which cited Micron’s strong margins and leadership position in high-bandwidth memory chips used in artificial intelligence systems.
Micron Chief Executive Sanjay Mehrotra has repeatedly emphasized that AI systems require dramatically more advanced memory technology and that demand is expected to remain strong for years. The company has already secured long-term supply agreements with major technology customers, including Nvidia and Google.
Other semiconductor leaders also moved higher. Nvidia and Broadcom gained ground, while the VanEck Semiconductor ETF rose approximately 5%, recovering a significant portion of last week’s losses.
The day’s market action highlighted two of the most powerful themes driving the economy in 2026: artificial intelligence and infrastructure investment.
While much of the public discussion around AI focuses on software platforms such as ChatGPT, Claude, Gemini, Microsoft Copilot, and Grok, the technology also requires massive physical infrastructure—from fiber-optic networks and power systems to advanced semiconductor manufacturing. The Amazon-Corning agreement underscores how AI investment is increasingly translating into American manufacturing jobs, workforce training programs, and long-term capital spending.
For investors, Monday’s rebound also served as a reminder that a growing share of market performance remains tied to a relatively small group of AI-related companies. Sharp swings in semiconductor stocks continue to have an outsized influence on major indexes, particularly the Nasdaq.
Looking ahead, markets remain focused on developments in the Middle East, Treasury yields, and the broader outlook for interest rates following last week’s stronger-than-expected jobs report. While investors appeared willing to buy back into AI-related names on Monday, the mixed finish suggests uncertainty remains just below the surface.
