Semiconductors

Sector thesis

Semiconductors are the tiny chips that power everything from your phone to data centers. They're made by a handful of companies globally, and they're incredibly hard to manufacture—which is why the sector matters so much. Right now, semiconductors are riding a genuine megatrend: the world needs more computing power than ever before, driven by AI, cloud services, and connected devices. This isn't hype—it's structural. Every major tech company and enterprise is building or upgrading data centers. That demand is real and likely to persist for years. Within semiconductors, there are three main buckets: design (companies that create chip blueprints), manufacturing (the actual factories that make them), and equipment (the machines that build the factories). Design companies like Nvidia have become household names because they sell chips for AI. Manufacturers like TSMC and Samsung run the fabs—the expensive factories. Equipment makers like ASML sell the tools to make chips smaller and faster. The biggest risks are cyclical: chip demand can swing wildly. When companies over-order, inventory piles up and prices crash. Geopolitics also matter—Taiwan makes most of the world's advanced chips, and that concentration is a real vulnerability. Finally, these companies require massive capital spending just to stay competitive, which can hurt profits in downturns. For a retail portfolio, semiconductors are a leveraged bet on AI and computing growth. You could own a diversified chip company, or pick a specific segment (design, manufacturing, or equipment) based on your conviction. Watch quarterly earnings for inventory levels and capital spending guidance—those signal whether demand is holding up or cooling. This sector can be volatile, so position sizing matters.
