BY THE NUMBERS

U.S. stock futures started off the new month higher Wednesday after the S&P 500 logged seven straight monthly gains, its longest winning streak since a 10-month run that ended in December 2017. The broader market index, while falling slightly Tuesday, rose 2.9% in August. The Dow and Nasdaq also fell a bit Tuesday but rose 1.2% and 4% in August, respectively.

Ahead of Wednesday's open, the Dow was just over 0.7% away from last month's record close. The S&P 500 and Nasdaq were just shy of Monday's record closes. September can be a perilous for stocks, with the month historically lower more often than higher. (CNBC)

ADP said on Wednesday that U.S. companies added just 374,000 jobs in August, far short of estimates for 600,000. ADP's look at July private sector jobs gains was also a big miss. These numbers have not been a great barometer during Covid of what the government's monthly jobs data might show. (CNBC)

Economists expect the Labor Department's report Friday to show 720,000 nonfarm payrolls additions in August and a dip in the nation's unemployment rate to 5.2%. The economy created a better-than-expected 943,000 new jobs in July as the unemployment rate dropped to 5.4%. The latest weekly tally of initial jobless claims is out Thursday. (CNBC)
