The PHLX Semiconductor Index rose 1.61% Monday after eight consecutive declines, recovering some ground after a weekly drop of more than 11% that put AI financing costs in focus.
Nasdaq’s final reading placed the index at 11,316.34, up 1.61% from its previous close. Reuters reported that the index had fallen more than 11% in the week through Oct. 16 and said the eight-day run of losses was its longest since October 2008.
The September inflation report added to concern about borrowing costs for heavily indebted AI companies, Reuters reported. The U.S. Bureau of Labor Statistics (BLS) said the Consumer Price Index rose 0.6% in September from August on a seasonally adjusted basis, following a 0.4% increase in August. The unadjusted increase over 12 months was 3.7%.
Treasury data showed the 10-year par yield at 5.15% Monday, up from 5.09% Friday. CoreWeave’s June 30, 2026, filing listed $35.068 billion in debt and $16.540 billion in lease liabilities. The company also cited the financing needed to expand data-center capacity as a business risk. Reuters, citing Tradeweb data, reported that the yield on a CoreWeave bond due in 2031 fell 19.5 basis points to 15.13% Monday.
Jay Woods, chief market strategist at Freedom Capital Markets, told Reuters that investors may need to decide whether they will continue to “pay a premium for that growth” during earnings season.
