NEW YORK, Aug 3 (Reuters) - The S&P 500 and the Dow Jones Industrial Average gained ground and the Nasdaq was essentially flat on Friday as positive earnings helped investors overlook heightened trade tensions and weaker than expected July jobs growth.
For the week, the S&P 500 and the Nasdaq looked set to post gains. The Dow was on track to post a weekly loss.
China upped the ante on the trade dispute, announcing new retaliatory tariffs on 5,207 goods imported from the United States, including liquefied natural gas (LNG) and some aircraft.
Chinese officials vowed to reciprocate earlier this week when the Trump administration proposed hiking tariffs to 25 percent on $200 billion worth of goods imported from China.
The trade-sensitive industrials sector edged down 0.1 percent.
"We have the trade war racking investors, on top of that we have some of the benefits from the tax cuts wearing off, and then after that the midterms," said Michael Geraghty, equity strategist at Cornerstone Capital Group in New York.
"'Strengthening headwinds' is going to be the phrase the second half of the year," Geraghty added. "Things become increasingly tougher for the markets to make a lot of progress."
A report from the Labor Department showed the U.S. economy added 157,000 jobs in July, fewer than the 190,000 economists expected, though the unemployment rate edged down to 3.9 percent.
Other data showed the U.S. trade deficit in June surged 7.3 percent to $46.3 billion, its biggest increase since November 2016. The politically sensitive trade gap with China widened by 0.9 percent to $33.5 billion.

The Dow Jones Industrial Average rose 93.52 points, or 0.37 percent, to 25,419.68, the S&P 500 gained 9.16 points, or 0.32 percent, to 2,836.38 and the Nasdaq Composite dropped 1.09 points, or 0.01 percent, to 7,801.59.
Of the 11 major sectors of the S&P 500, nine were in positive territory.
