As the Q1 earnings season comes to a close, it’s time to take stock of this quarter’s best and worst performers in the electronic components & manufacturing industry, including Amphenol (NYSE: APH) and its peers.

The sector could see higher demand as the prevalence of advanced electronics increases in industries such as automotive, healthcare, aerospace, and computing. The high-performance components and contract manufacturing expertise required for autonomous vehicles and cloud computing datacenters, for instance, will benefit companies in the space. However, headwinds include geopolitical risks, particularly U.S.-China trade tensions that could disrupt component sourcing and production as the Trump administration takes an increasingly antagonizing stance on foreign relations. Additionally, stringent environmental regulations on e-waste and emissions could force the industry to pivot in potentially costly ways.

The 10 electronic components & manufacturing stocks we track reported an exceptional Q1. As a group, revenues beat analysts’ consensus estimates by 3.8% while next quarter’s revenue guidance was in line.

Market Update

Late in 2025 into early 2026, there was hand wringing around artificial intelligence. For software companies, the fear was that AI would erode pricing power and compress margins as new tools made it easier to replicate what once required expensive enterprise platforms. Crypto investors had their own version of the same anxiety: if AI agents could trade, allocate capital, and manage wallets autonomously, what exactly was the long-term value of today’s crypto infrastructure?

These concerns triggered a noticeable rotation away from these sectors and into safer havens. But markets rarely dwell on one narrative for long. Spring 2026 came, and the focus shifted abruptly from technological disruption to geopolitical risk. The US’ conflict with Iran became the dominant driver of market psychology, and when geopolitics takes center stage, the script changes quickly. Investors stop debating growth rates and start worrying about oil supply, inflation, and global stability.
