Semiconductors and AI: stress is concentrated in infrastructure and has not yet spread across Wall Street
The SOXX semiconductor index hit a recent high on October 5 and has since fallen about 18.6%, while CoreWeave is down around 34.8%, Vertiv 23.4% and AMD 19.1%, against a decline of roughly 1.5% for the S&P 500. The deterioration is concentrated in AI infrastructure: high yield is starting to move alongside semiconductors and its spreads widened about 15 basis points, but investment grade and long-term Treasuries are still holding up.
