Nasdaq Slides as Oil Prices Rise and Semiconductor Shares Come Under Pressure
Thursday’s US session ended with the Nasdaq down about 1.25%, the S&P 500 lower and the Dow narrowly higher as energy concerns hit technology sentiment.

US equities finished Thursday, October 8, on a mixed note, with selling concentrated in technology and semiconductor shares. Reuters reported a decline of about 1.25% for the Nasdaq Composite and 0.47% for the S&P 500, while the Dow Jones Industrial Average edged higher by 0.10%.
One source of pressure was crude oil. Fears about Middle East supply disruptions and reduced US production lifted energy prices and revived concern about inflation. Higher energy costs can complicate the outlook for interest rates, especially when bond yields are already elevated.
A separate focus was the economics of the AI expansion. Investors reacted to reports questioning the revenue trajectory and financing demands behind major AI projects, and several chip-related shares declined. The session illustrated a familiar market split: an index with heavy growth-stock exposure can struggle even when older industrial and energy-linked companies hold up better.
These are closing-session figures, not live market quotations. Friday’s positioning may change as fresh economic and geopolitical information emerges.
