$Taiwan Semiconductor(TSM.US)is currently executing an aggressive, multi-node expansion strategy that defies historical industry caution, simultaneously ramping 3nm volume, mass-producing 2nm, and preparing for a late-2026 launch of 1.6nm technology; this technological dominance has driven the stock to $397.98 (+4.00% today), supported by insatiable AI demand and a clear roadmap extending to 2029, though investors must weigh this against geopolitical concentration risks and premium valuation multiples.
