As the Q4 earnings season wraps, let’s dig into this quarter’s best and worst performers in the electrical systems industry, including Allegion (NYSE: ALLE) and its peers.

Like many equipment and component manufacturers, electrical systems companies are buoyed by secular trends such as connectivity and industrial automation. More specific pockets of strong demand include Internet of Things (IoT) connectivity and the 5G telecom upgrade cycle, which can benefit companies whose cables and conduits fit those needs. But like the broader industrials sector, these companies are also at the whim of economic cycles. Interest rates, for example, can greatly impact projects that drive demand for these products.

The 15 electrical systems stocks we track reported a satisfactory Q4. As a group, revenues beat analysts’ consensus estimates by 2.1% while next quarter’s revenue guidance was 1.3% below.

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.
