Amphenol’s stock is surging on the back of record Q2 earnings, fueled by AI-driven demand and strategic acquisitions. The company’s 57% sales growth and 110% EPS increase have ignited investor optimism, while technical indicators suggest a continuation of the upward trend. With AI infrastructure and defense markets expanding, APH’s rally reflects broader sector tailwinds and strong operational execution.

Record Q2 Earnings and AI Momentum Fuel APH's Rally
Amphenol’s 3.6% intraday surge is directly tied to its record Q2 2025 results, which included 57% sales growth to $5.7 billion and 110% EPS increase to $0.86. The company attributed its performance to strong organic growth in IT datacom and defense markets, bolstered by the recent acquisition of Narda-MITEQ. Analysts highlighted AI infrastructure demand as a key driver, with Barron’s and Zacks noting APH’s positioning in high-growth sectors. Additionally, the stock’s 3.38% price action aligns with analyst upgrades and positive sentiment around its 25.6% operating margin and $1.1 billion free cash flow.

Electronic Equipment Sector Gains Momentum as APH Outperforms
The Electronic Equipment, Instruments, and Components sector is seeing mixed momentum, with Amphenol outperforming peers. While TE Connectivity (TE) rose 5.37% on industrial demand, APH’s 3.6% gain reflects its unique focus on AI infrastructure and defense. Sector news highlights include Rigol’s real-time spectrum analyzers and Bosch’s chip manufacturing collaboration, but APH’s rally is driven by its own earnings strength and strategic acquisitions. The sector’s 18% Q2 datacenter infrastructure growth underscores broader AI tailwinds, but APH’s 57% sales growth and 25.6% operating margin position it as a standout performer.

Backtest Amphenol Stock Performance
It looks like the event-backtest engine aborted because the 4 %-surge signal list it received was empty, so the underlying statistics routine could not calculate any post-event returns.In other words, from 2022-01-01 to 2025-09-18 APH never closed more than 4 % above the previous day’s close (using daily close-to-close percentage change as the trigger), so there are no events to back-test.How would you like to proceed?1. Use a different definition of “intraday surge” (e.g. high-to-open ≥ 4 %, or close-to-open ≥ 4 %) 2. Lower the threshold (e.g. 3 %) 3. Stop here and simply note that there were no qualifying 4 % daily surges in the periodLet me know which option works for you (or suggest another), and I’ll rerun the back-test accordingly.
