Stock Market Today, Sept. 8: Stocks Slide Amid Surging Oil Prices, Persistent Geopolotical Tenisons

The Dow Jones Industrial Average (DJINDICES:^DJI) fell 1.18% to 52,786, the S&P 500 (SNPINDEX:^GSPC) lost 0.58% to 7,674, and the Nasdaq Composite (NASDAQINDEX:^IXIC) dropped 0.31% to 26,424 as rising crude oil prices and trade tensions weighed on sentiment.

Today's biggest moves

Intel (NASDAQ:INTC) shares climbed as the company plans to raise processor prices by up to 10% to improve its margins.

Corning (NYSE:GLW) rose 7% today after agreeing to supply 80 million miles of high-density optical fiber to Verizon (NYSE:VZ) as the latter builds its "network of the future."

Conversely, Amgen (NASDAQ:AMGN) shares slid 10% alongside Novartis (NYSE:NVS) after NVS stock reported a Phase 3 trial setback for its pelacarsen injectable, which was supposed to help with heart disease. Amgen has a similar treatment, olpasiran, and analysts are worried this indicates it may meet a similar fate as Novartis' drug.

What this means for investors

Markets continued to take a breather today as trade tensions, Middle East conflicts, and surging oil prices persisted -- but this is nothing new, especially for 2026.

There were plenty of individual stock-specific news items, however, such as the ones mentioned above and Qualcomm (NASDAQ:QCOM) signing a major AI chip deal with Amazon (NASDAQ:AMZN). The deal helps Qualcomm continue diversifying beyond smartphones and gives Amazon the option to buy up to $60 billion in AI data center chips.

Lastly, as of 5 p.m. ET, Midwestern pizza chain and c-store chain Casey's General Store (NASDAQ:CASY) is down 10% after reporting analyst-beating earnings but offering conservative guidance.
