U.S. stocks opened lower Tuesday after the Labor Day weekend, with the Dow Jones Industrial Average falling about 540 points as elevated Treasury yields, renewed inflation concerns and a stronger-than-expected jobs report increased expectations of a Federal Reserve rate increase at its Sept. 15-16 meeting. Around 9:45 a.m. ET, the Dow was down roughly 1% near 52,870, the S&P 500 was around 7,707, down about 0.2%, and the Nasdaq Composite was near 26,507, down roughly 0.3%. The 10-year Treasury yield was near 4.78% in early trading, while futures markets put the probability of a September rate increase at 60.6%, according to CME FedWatch data cited by Reuters. The August labor report showed 162,000 jobs added and unemployment at 4.1%. Technically, the Dow fell below its 50-period exponential moving average (trend-following price average) near 53,237 and was testing support around 52,800 to 52,900. A sustained break could expose 52,000, while recovering 53,200-53,300 would be the first bullish step, followed by resistance around 53,700 to 54,000. The S&P 500 remained above its rising 50-period average near 7,670, with support at 7,650-7,670 and resistance around 7,750 and 7,800. The Nasdaq stayed above its 50-day average near 26,060, with support at 26,000-26,100 and potential resistance around 26,700-26,800 and 27,100-27,200. HSBC raised its year-end S&P 500 target to 8,100 from 7,650, citing stronger corporate earnings and continued AI infrastructure spending, and expects earnings per share to grow more than 25% in the second half of 2026. Losses in Microsoft, Alphabet and Apple contrasted with gains in Intel, AMD, Broadcom and Tesla. Investors now await the August Producer Price Index on Thursday and Consumer Price Index on Friday, which could influence whether the Federal Reserve raises rates next week or waits for more inflation evidence.
