Amphenol holds key level after AI datacom-fueled rally

Amphenol's move comes against a broader rotation out of tech stocks. That rotation has not dampened investors' enthusiasm for a few artificial intelligence infrastructure names, and Amphenol is one of them, according to the article. The stock had already rallied on earnings, driven by strong AI datacom sales, and reached an all-time high in June before falling below its 50-day moving average.

Now, as an IBD 50 Stocks To Watch pick, Amphenol is holding support at a key technical level within a base. The article frames this as a test: the stock has not fallen further, but it is still below its 50-day moving average, so the base is forming after a pullback rather than a fresh breakout.

The stakes hinge on whether the support level holds and the stock can work back toward its June high. That outcome matters to investors watching AI infrastructure names, since Amphenol is being treated as a bellwether for whether enthusiasm in that narrow group can persist even as the wider tech sector rotates.
