NEW YORK, December 29, 2025, 9:54 PM ET — Market closed
- Amphenol shares closed down 0.4% on Monday, tracking a tech-led dip in U.S. equities.
- Investors are focused on U.S. data and Federal Reserve signals as markets head into a holiday-thinned week.
- Amphenol is scheduled to report fourth-quarter 2025 results on Jan. 28.
Amphenol Corp shares fell 0.4% to end at $136.90 on Monday, as heavyweight technology names retreated and pulled the broader market lower in the final week of 2025.
The move matters now because Amphenol sits at the intersection of industrial and tech spending: it sells connectors, sensors and high-speed cables used in data communications and other end markets that often trade with investor sentiment toward big tech and AI-linked hardware demand.
With trading conditions typically thinner into year-end, swings tied to positioning can have an outsized impact on suppliers like Amphenol, even without company-specific news. Wall Street also has fresh Fed signals on deck, keeping rate-sensitive growth and tech-adjacent names in focus.
On Monday, the Dow fell 0.51%, the S&P 500 lost 0.35%, and the Nasdaq slid 0.50%, Reuters reported, with the information technology sector weighing on the benchmark index.
“(It’ll) turn out to be a buying opportunity,” Hank Smith, director and head of investment strategy at Haverford Trust, told Reuters, arguing that valuations for top tech names (excluding Tesla) were not “challenging” given growth and financial strength. Reuters
Other tech-linked stocks were also lower in late trading, with Nvidia down about 1.2%. Shares of connector peer TE Connectivity and power-management firm Eaton were modestly lower as well.
Amphenol traded between $135.83 and $137.59 during the session, with about 4.3 million shares changing hands, according to market data.
In late after-hours trading, the stock last changed hands near $137.44, roughly 0.4% above the regular-session close, as liquidity tapered off into the evening.
Before Tuesday’s session, investors will watch the S&P CoreLogic Case-Shiller home price index at 9:00 a.m. ET and the Chicago PMI — a regional gauge of business activity — at 9:45 a.m. ET.
The Federal Reserve is also scheduled to release minutes from its Dec. 9–10 meeting at 2:00 p.m. ET on Tuesday, according to the central bank’s calendar.
For Amphenol, near-term technical levels are clear: Monday’s low around $135.83 marks the first support area traders will eye, while the day’s high near $137.59 is an immediate resistance level if risk appetite improves.
The next company catalyst is earnings. Amphenol is scheduled to report fourth-quarter 2025 results on Jan. 28, when investors will be looking for updates on demand across its communications and harsh-environment end markets and any commentary on data-center-related spending.
Markets are closed on Thursday for New Year’s Day, a calendar wrinkle that can compress positioning and amplify reactions to Tuesday’s data and the Fed minutes ahead of the final trading sessions of the year.
