NEW YORK, Sept. 1 (Xinhua) -- U.S. stocks posted solid weekly gains as investors closely monitored trade talks between the United States and its neighbors while digesting a batch of key economic data.
For the week, the Dow rose 0.7 percent, the S&P climbed advanced 0.9 percent, and the Nasdaq gained 2.1 percent.
Trade concerns have kept a lid on stock gains in recent months as investors assessed the potential impact of protectionist trade policies on the global economy.
U.S. President Donald Trump announced Monday that the United States and Mexico had reached a preliminary bilateral trade pact that would replace the North American Free Trade Agreement (NAFTA) and that Canada should join the deal or face tariffs against Canada's automobile manufacturing industry.
The United States and Canada failed to meet the Friday deadline imposed by the Trump administration to revamp the NAFTA trade agreement as major differences remain in bilateral talks.
It is unclear whether the United States and Canada will work out their differences in the next few weeks.
On the economic front, consumer sentiment in the United States rose slightly in August, opposite to economists' expectation, according to University of Michigan's monthly survey. The consumer sentiment index hit 96.2 in the final reading of the month.

The number of Americans filing for unemployment benefits rose last week, but the underlying trend continued to point to a tightening labor market that should keep the economy on a strong growth path this year.

The four-week moving average was 212,250, a decrease of 1,500 from the previous week's unrevised average of 213,750. This is the lowest level for this average since Dec. 13, 1969 when it was 210,750, said the department.
The Commerce Department said on Wednesday that Economic growth was stronger during the second quarter than earlier estimated.
Real gross domestic product (GDP), the value of all goods and services produced across the economy, rose at a 4.2 percent annual rate in the second quarter, adjusted for seasonality and inflation.
The figure was higher than the 4.1 percent annual rate the department estimated earlier.

"Even as home prices keep climbing, we are seeing signs that growth is easing in the housing market," said David Blitzer, managing director and chairman of the index committee at S&P Dow Jones Indices in a release.
"Sales of both new and existing homes are roughly flat over the last six months amidst news stories of an increase in the number of homes for sale in some markets," said Blitzer.
