What's driving TSM's price action

The story driving TSM right now: Taiwan Semiconductor Manufacturing (TSM) is a unique and powerful player in AI logic chip manufacturing, with its stock currently trading around $430, an elevated valuation of 31 times earnings justified by management's forecast of strong chip demand through 2029-2030 and sustained growth. High volatility-momentum readings (100) indicate significant narrative-driven price displacement.
