US market today: Wall Street drifts on weak ADP jobs data; treasuries gain as yields fall

US stocks drifted on Wednesday. Job market signs caused investor caution. The S&P 500, Dow Jones, and Nasdaq saw declines. An ADP report showed job cuts in September. This report also revised August employment down. Treasury yields fell. A government shutdown may delay official job data. This created market uncertainty. Individual stocks performed differently. Cal-Maine Foods fell. Nike rose.
