On July 29, Microchip Technology fell 5.47% in regular trading, trading at $71.735/share, with turnover of $240 million. The decline came amid a broad semiconductor sector rout as markets intensified questioning of AI capital expenditure return efficiency.

The selloff was driven by multiple converging headwinds. Investors grew increasingly skeptical that massive AI infrastructure spending by tech giants—projected to reach $700 billion combined this year—can generate adequate returns within a reasonable timeframe. Since GPU procurement demand directly determines data center rack utilization rates, any downward revision in AI chip demand expectations pressures data center leasing and pricing logic across the supply chain. Meanwhile, concerns over NVIDIA's reported circular financing model for AI infrastructure deals and prominent short-seller Michael Burry's expanded bearish bets on the semiconductor sector further amplified selling pressure.

The Philadelphia Semiconductor Index extended its decline, falling over 20% from its June highs. Peer stocks were broadly weaker, with Micron Technology down 6.02%, AMD down 6.13%, Intel down 4.31%, and NVIDIA down 2.63%.
