The Dow Jones Industrial Average and S&P 500 futures both fell by about 0.5%, while the Nasdaq 100 contract dropped by 0.8%. After a strong performance in August, investors are uneasy about the market outlook for September, especially against the backdrop of volatile oil prices and expectations of interest rate increases. On Tuesday, relevant labor market data will be released one after another, providing the latest information on hiring and layoffs.
