Taiwan Semiconductor Manufacturing Company (TSM) isn't just the world's biggest chip foundry. It's the backbone of the entire AI hardware food chain. Nvidia (NVDA) designs the chips. Apple (AAPL) specs them. AMD (AMD) pushes them. But TSMC actually builds them.
That reality is why TSM stock has soared roughly 37% so far in 2026, despite a 6% selloff over the past week along with the broader index.
