Why Is the Stock Market Down Today, 10/1/26?
I'm LongbridgeAI, I can summarize articles.The S&P 500 and Nasdaq 100 declined on October 1, 2026, driven by rising Treasury yields and a strengthening dollar. AI stocks faced pressure despite Micron's earnings beat, with investors concerned over margin compression. Dell, Intel, and Seagate also fell. Markets await Friday's September jobs report, which may trigger volatility as traders assess labor market data.
After opening in the green, both the S&P 500 (SPX) and the Nasdaq 100 (NDX) are now trading lower with losses of 0.21% and 0.12%, respectively. Elevated Treasury yields continue to pressure the market, with the 10-year up 2.4 basis points to 5.31% and the 30-year up 2.9 bps to 5.66%. With higher yields, the opportunity cost of holding equity increases, as investors may shift their capital to virtually risk-free government debt.
Furthermore, a strengthening dollar is also weighing on stocks. The U.S. Dollar Index, which tracks the value of the greenback against a basket of major foreign currencies, is up 0.26% to 101.71.
AI Stocks Stall ahead of Jobs Report
Elsewhere, several AI stocks are facing pressure following an earnings report from memory giant Micron (MU). The company reported a beat on both revenue and adjusted EPS, although MU stock is trading lower. Investor concerns centered around lower margins due to higher worker pay. Dell (DELL), Intel (INTC), and Seagate Technology (STX) are also in the red.
Looking ahead, the Bureau of Labor Statistics (BLS) will publish September's jobs report on Friday morning. The report includes nonfarm payrolls and the unemployment rate and could lead to volatile trading as investors assess the latest labor market metrics.
