TSMC reports 51% third-quarter revenue growth, but shares and AMD slide

TSMC reported Q3 revenue up 51% YoY, reinforcing that AI-related chip demand remains strong. However, the stock still fell and weakness spilled into peers such as AMD, suggesting positioning, valuation sensitivity, or broader risk-off factors are dominating near-term price action despite supportive fundamentals. The divergence highlights that AI hardware strength is acknowledged, but not sufficient to lift semiconductor equities in the immediate term.
