Momentum Meets Value: Amphenol Stock Could Be A Good Buy

We think Amphenol (APH) stock might be a good investment candidate. Why? Because you get strong margin, low-debt capital structure, and strong momentum – with room to run as the stock is meaningfully below its 52-week high.

There Are Several Things In Favor Of APH Stock

APH stock can run given its good fundamentals and the fact that it is 18% below its 52-week high.

Recent record Q4 2025 orders, notably a 1.31 book-to-bill ratio, are fueled by robust AI-driven IT datacom demand and broad strength in defense and automotive markets. This strong volume and favorable product mix, coupled with pricing power, underpin the sustained 27.5% Q4 adjusted operating margin. While the recent CommScope acquisition increased leverage, with pro forma net leverage at 1.8 times, and initially impacted margins, record 2025 free cash flow of $4.4 billion provides financial flexibility. Despite a recent stock dip from integration concerns, Q1 2026 guidance remains strong, reflecting continued market opportunities.

And Its Fundamentals Look Good

• Long-Term Profitability: About 20.1% operating cash flow margin and 22.2% operating margin last 3-year average.
• Strong Momentum: Currently in the top 10th percentile of stocks in terms of “trend strength” – our proprietary momentum metric.
• Revenue Growth: Amphenol saw revenue growth of 47.4% LTM and 20.7% last 3-year average, but this is not a growth story
• Room To Run: Despite its momentum, APH stock is trading 18% below its 52-week high.

But Be Wary Of The Risks

While APH stock may be a compelling investment opportunity, it’s always helpful to be aware of a stock’s history of drawdown. APH slid 57.5% in the Dot-Com crash and 63.4% during the Global Financial Crisis. The stock also fell 28.7% in the recent inflation shock and dropped over 37% amid the Covid turmoil. Even the 2018 correction hit it hard, with a 22% dip. So, despite the solid fundamentals, APH hasn’t been immune to big sell-offs when markets turn south. But the risk is not limited to major market crashes. Stocks fall even when markets are good – think events like earnings, business updates, outlook changes.
