Taiwan Semiconductor Manufacturing Company (TSMC) has seen its shares nearly double over the past year, now trading around $426, outpacing the Computer and Technology sector’s 48.2% gain and the S&P 500’s 30% rise. The company reported a 39% year-over-year revenue increase in Q1 2026, driven largely by high-performance computing, which accounted for 61% of its total revenues. TSMC anticipates revenue growth of over 30% in 2026, supported by a capital spending forecast of $52 billion to $56 billion.

Despite strong fundamentals, concerns grow as TSMC’s stock has rapidly appreciated, raising questions about potential overvaluation amid heavy reliance on a few large AI customers. The company maintains an advanced semiconductor manufacturing position, yet industry constraints are expected to persist until 2027.

Currently, TSMC trades at a forward P/E ratio of 25.0x, slightly above its historical median of 21.3x, but remains within reasonable valuation compared to the broader technology sector, reflecting a strong market outlook backed by demand for AI technologies.
