The New York Stock Exchange rose slightly in the opening on Friday, after the publication of mixed indicators, again relying on progress in Sino-US negotiations.

Its leading index, the Dow Jones Industrial Average, rose 0.29% to 26,968.57 points around 13:40 GMT.

The Nasdaq, with strong technological coloration, took 0.03% to 8,033.26 points and the expanded S & P 500 index was up from 0.14% to 2,981.81 points.

Wall Street had finished small on Thursday, weakened by the revelations of a whistleblower around a phone call from Donald Trump to the Ukrainian president and a renewed fears over the discussions between Washington and Beijing: the Dow Jones had fell by 0.30% and Nasdaq by 0.58%.

Brokers were encouraged Friday by CNBC reports that high-level bargaining between Chinese and US officials is expected to resume on Oct. 10.

US Treasury Secretary Steven Mnuchin has already confirmed Monday that he will, along with US Trade Representative Robert Lighthizer, resume discussions with their Chinese counterparts in early October.

But CNBC's information "reinforces commercial optimism and eclipses growing political rumors in Washington and the uncertainties of global growth," said Charles Schwab's analysts.

The 18-month-long trade showdown between the United States and China, which is weighing on global growth, is indeed the main concern of the markets at the moment and all the news on the subject, in a sense or in the other, in general shivers the clues.

Investors also kept an eye on the White House affair after accusations of a whistleblower accusing Donald Trump of "soliciting Ukraine's interference" in his re-election campaign and his entourage to have tried to keep this step secret.

The Democrats have launched an impeachment procedure against the American president.

The indicators of the day on the economy of the United States were on their side rather contrasted.

According to the PCE index of the Department of Commerce, annual inflation was established in August to 1.4% for the fourth month in a row, remaining far from the 2% targeted by the US Central Bank.

Underlying inflation, that is, excluding prices in the highly volatile food and energy sectors, continued to accelerate to 1.8%.

Household incomes, for their part, recorded an increase in line with expectations (+ 0.4%), while their expenditure slowed significantly (+ 0.1% after + 0.5%).

In the bond market, the 10-year US debt rate stood at 1.703%, down from the previous day's close (1.692%).
