This semiconductor sell-off stems from a convergence of tech-cycle saturation, valuation excesses, and macro tightening. Broadcom’s AI demand warning reveals looming overcapacity in 3nm/EUV nodes, triggering downstream procurement delays and upstream equipment order softness—especially for ASML. Persistent high rates elevate capital costs, while entrenched U.S. export controls inflate compliance burdens, notably for firms with advanced packaging operations in Taiwan, China. In response, Nvidia may accelerate vertical integration to lock in customers, while Intel could leverage its foundry push to capture outsourced orders from weakened players like Marvell. Over the next 12–24 months, expect brutal market pruning: ‘AI narrative’ stocks without real revenue will trade at steep discounts, while those mastering HBM3e volume production and CoWoS supply chains will build durable moats. The frenzy is over—but structural opportunities are just emerging.
