Summary Box: Economic signals give stocks a lift

JOB BOOST: Good news on private sector employment helped get the stock market back on an upward track. Payroll company ADP said private employers increased hiring last month.

BACK ON THE UPSWING: The 44 point gain in the Dow Jones industrials easily wiped out the 38 point loss from a day before, and seemed to restart the market’s upward momentum. The Dow has gained 10.3 percent since closing at its lowest level of the year on July 2.

LOOKING AHEAD: The market’s gains were held in check ahead of a key report due Friday from the Labor Department on monthly employment figures.
