Not Nvidia. Not Micron. After the Chip Sell-Off, I'd Buy This AI Stock and Hold It Forever.

Following a 30% semiconductor sector decline, the author recommends Taiwan Semiconductor Manufacturing (TSMC) as the best AI chip stock to buy and hold, citing its dominant 73% market share in contract semiconductor manufacturing, virtuous cycle of reinvestment, and stable earnings. While Nvidia and Micron have also declined, TSMC's irreplaceable role in supply chains and predictable business model make it more attractive than faster-growing but more volatile competitors.
