Taiwan Semiconductor (TSM) Stock Is Down Nearly 15% This Month Despite Record AI Demand. Here Is Why

TSM delivered exceptional Q2 earnings with net profit surging 77% year-over-year to a record T$706.6 billion, substantially exceeding consensus estimates by over 13%. Despite this earnings beat and sustained AI-driven semiconductor demand, the stock has declined nearly 15% this month, creating a valuation disconnect typical of mature chip leaders facing elevated investor expectations.

The paradox reflects market psychology around semiconductor cycles and positioning risk. Record profitability amid AI acceleration should theoretically support stock momentum, yet institutional investors appear to be rotating away from foundry leaders or reassessing growth multiples. This suggests either profit-taking after a sustained rally, concern over China-related supply chain dynamics, or realization that current valuations embed maximum-growth assumptions that earnings alone cannot exceed.

Supply chain partners like ASML, the critical lithography equipment supplier, and downstream customers such as AAPL face mixed signals: demand strength is undeniable, but margin sustainability and geopolitical headwinds create uncertainty. The disconnect between TSM's financial performance and stock price indicates the market is pricing in late-cycle risks rather than rewarding operational excellence.

Sector implication: Technology's near-term weakness despite semiconductor strength suggests rotation toward defensive positioning or concerns about AI capex sustainability. This divergence warrants monitoring of institutional flows and forward guidance revisions from chipmakers to clarify whether weakness reflects valuation reset or demand deceleration.
