Semiconductor Stocks Fall as PHLX Chip Index Suffers Seven-Day Losing Streak

U.S. semiconductor shares have experienced a broad decline, with the PHLX Semiconductor Index dropping for seven consecutive sessions. Such a prolonged losing streak has occurred only 15 times since 1994, pulling the benchmark down nearly 14% from its October 6 close. The downturn is also hitting semiconductor-focused funds, including the Invesco PHLX Semiconductor ETF (SOXQ) and the Roundhill Memory ETF (DRAM), which has dropped 21% since October 5.

The sell-off is being driven by market fears surrounding memory supply and broader economic conditions. Chinese manufacturer ChangXin Memory Technologies recently made progress on a denser memory chip design, raising concerns among investors about potential future market oversupply. At the same time, U.S. producer prices climbed 6.3% year-over-year in September, marking the fastest annual increase since December 2022. Higher inflation keeps open the possibility of Federal Reserve interest rate hikes, which raise borrowing costs and increase the expense of constructing artificial intelligence data centers.

Investors are closely watching whether higher capital costs will dampen capital expenditure in AI infrastructure and reduce demand for suppliers of memory, storage, and chipmaking tools. Individual tech equipment suppliers, such as Coherent Corp. (COHR), Teradyne, Inc. (TER), and Seagate Technology Holdings PLC (STX), remain under pressure as the market re-evaluates spending across the chip industry.

Questions and answers

Why are semiconductor stocks falling?

Chip stocks are falling due to fears of future oversupply after ChangXin Memory Technologies announced denser memory chip progress, combined with rising U.S. producer prices that could lead to higher Federal Reserve interest rates and increased AI data center costs.

How much has the PHLX Semiconductor Index dropped?

The PHLX Semiconductor Index has declined nearly 14% from its October 6 close after falling for seven consecutive sessions.

How do higher interest rates affect artificial intelligence chipmakers?

Higher interest rates make borrowing more expensive, raising the costs required to build AI data centers. This leads investors to sell off stocks in companies that supply memory, storage, and semiconductor tools for those facilities.
