US stocks were higher at midday Friday amid erratic trade that analysts attributed to competing headlines over the August US jobs report and the G20 debate among global leaders over Syria.
At 1645 GMT, the Dow Jones Industrial Average was up 9.3730.56 (0.06 percent) to 14,946.85.

The Labor Department said the US added 169,000 jobs in August, below analyst projections of 177,000. The report also lowered the estimates for jobs added in June and July.

"The futures were up because the initial reaction was 'Hey, that means the Fed is not going to taper,' but the market has to start questioning why the Fed is not tapering," said Michael Gayed, chief investment strategist at Pension Partners.
The continuing dispute between Russia and the US over Syria also troubled investors, as US President Barack Obama and Russian counterpart Vladimir Putin failed Friday to end their bitter dispute over US military action against Damascus at the G20 meeting.
