Its end markets include AI and IT datacom, communications networks, industrial applications and defense; customers include equipment makers and other businesses integrating these products into their systems.

Notable Price Movement
- Oct 26-30$79.307.03%
APH rose $9.01, or 12.33%, over the supplied weekly comparison, closing at $82.08 after a steady climb from $75.27 on October 26. The main catalyst was the October 28 Q3 report: Amphenol posted record sales and earnings, with Zacks reporting year-over-year revenue growth of 65.1% and an earnings increase of 73.9%. Management highlighted strong AI-related IT datacom demand, record orders and a stronger 2026 outlook, though communications-network weakness remained a counterpoint. Broad industrial growth and contributions from acquisitions added support. The company also announced a 20% quarterly dividend increase and a new $4 billion repurchase program. Shares rose on each supplied trading day, with no material reversal.
- Oct 19-23$74.096.63%
Amphenol fell 6.86% from $86.19 on October 12 to $80.28 on October 19. The clearest reported driver was a pullback from AI-infrastructure stocks ahead of the company’s October 28 earnings report, as investors reassessed the group’s exposure to volatile hyperscaler spending. Shares declined each day from October 13 through October 16, with the heaviest trading volume on October 15, then recovered modestly on October 19. Coverage also pointed to premium valuation as a concern, despite strong bookings and margin expansion. The supplied evidence identifies no company-specific announcement or analyst action that explains the decline; the move appears tied chiefly to sector sentiment and positioning before earnings.
- Oct 12-16$79.359.04%
Amphenol fell 1.24% over the reported week, from $87.27 to $86.19. The supplied evidence does not identify a company-specific catalyst for the decline, so the move appears to reflect trading rather than a documented company announcement. The available daily closes show a choppy path: shares rose to $88.62 on October 6, slipped to $87.55 the next day, then dropped to $85.32 on October 8 as volume increased to 13.0 million shares. They rebounded to $87.24 on October 9 before falling to $86.19 on October 12. No market benchmark or broader market news is provided to explain the swings.
- Oct 5-9$87.240.32%
Amphenol rose 5.07%, from $84.34 to $88.62, over the supplied period. The shares were nearly unchanged on September 30 after slipping slightly, then advanced on each reported session from October 1 through October 6, with no material reversal. The evidence does not identify a dated company announcement or other specific catalyst for the gain. Coverage points to continuing enthusiasm for AI-related data-center demand and rising earnings estimates, alongside repeated analyst optimism, but does not establish that either drove trading on a particular day. The available headlines also flag premium valuation and reliance on continued AI-infrastructure spending as counterweights. The supplied closes show a steady climb rather than a sharp reaction to a disclosed event.
- Sep 28 - Oct 2$86.963.41%
Amphenol rose $2.59, or 3.12%, from $83.08 on September 24 to $85.67 on October 1. The stock advanced to $84.09 on September 25 and $84.62 on Monday, then slipped modestly over Tuesday and Wednesday to $84.30 before jumping to the week’s closing high on Thursday. The supplied evidence identifies no dated, company-specific event behind the move. Coverage during the period emphasized AI-related demand for connectivity and data-center infrastructure, while one market commentary described U.S. stocks as advancing with AI leadership; those themes offer context but are not tied to a specific trading-day catalyst. Trading volume was highest on Wednesday, at 15.8 million shares, during the small pullback.
- Sep 21-25$84.098.43%
APH rose 6.38%, from $77.26 to $82.19, over the quoted period. Trading was strongest early in the week: the shares closed at $80.72 on September 21, climbed to $82.84 on September 22, then slipped to $82.19 on September 23, giving back part of Tuesday’s advance but ending above Monday’s close. The supplied evidence does not identify a company-specific announcement or analyst action that explains the move. It also provides no index or sector performance with which to assess broader-market influence, so the advance cannot be tied to a documented market catalyst. The available trading record shows a material rise followed by a modest pullback, rather than a sustained late-week reversal.
- Aug 24-28$78.870.46%
Amphenol rose $0.73, or 0.46%, over the week, finishing at $157.74 after a volatile round trip. The stock fell 0.9% Monday to $155.55, then gained 2.1% Tuesday and 1.6% Wednesday, holding nearly flat Thursday before giving back 2.3% Friday. The supplied evidence contains no dated company-specific announcement that clearly explains those reversals. Investor-facing commentary remained constructive on AI-driven IT datacom demand, an 85% year-over-year increase in Communications Solutions revenue and Q3 sales guidance of $9.3–9.4 billion, while technical coverage noted a breakout above the 50-day moving average. Valuation articles offered a counterweight, citing the stock’s 323% run and estimates ranging from $100 to near $189.
- Aug 10-14$83.561.22%
Amphenol rose $4.36, or 2.67%, from $163.34 to $167.70 over the week, but the move was uneven. Shares jumped $7.99 on August 4 to $171.33 on the heaviest volume of the period, added modestly on August 5 to $172.24, then gave back $3.06 across August 6-10. The principal identifiable drivers were optimism about a broadening AI-interconnect opportunity and continued interest in Amphenol’s AI-infrastructure exposure. Investors also appeared to look past concerns that copper could displace some connector demand, a theme highlighted in contemporaneous coverage. No dated company announcement, earnings release, contract, or guidance change was supplied to explain the sharp Tuesday advance, so the week reflected changing sentiment around AI growth and materials risk rather than a clearly documented corporate catalyst.
- Aug 3-7$84.595.28%
Amphenol rose $27.48, or 19.10%, from $143.85 to $171.33 over the reported period. The advance began with successive gains from July 29 through August 4, including a $7.99 jump on the final day, rather than a material within-week reversal. The main catalyst was coverage of record second-quarter results: sales reached approximately $8.8 billion, up 55% year over year in U.S. dollars and 30% organically, with AI-infrastructure demand, strong orders and broad connectivity-market strength highlighted. Reports also emphasized acquisitions, including CommScope, as expanding Amphenol’s AI reach and lifting 2026 expectations. An ETF-flow report mentioned APH among notable inflow names, while broader market weakness elsewhere did not prevent the company-specific rally.
