The relentless rally in artificial intelligence semiconductor stocks is encountering fresh resistance as investors grow increasingly wary of stretched valuations and the long-term sustainability of capital expenditure growth.
Market participants are questioning whether the robust revenue streams driving the sector's recent outperformance can be maintained at current multiples, leading to a shift in sentiment from pure momentum to cautious reassessment.
