Wall Street opened up on Friday for the last session of a tough week, with some optimism prevailing over the subsequent trade negotiations between the United States and China.

The Dow Jones gained 0.53% to 25,715.47 points and the Nasdaq gained 1.10% to 7,851.66 points at 14:05 GMT.

The broad S & P 500 index rose 0.82% to 2,870.95 points.

The yields of the major 2-year, 10-year, and 30-year US borrowings rose sharply, after having hit record lows the day before as investors tried to find a safe haven for their money.

On Thursday, the indexes oscillated between falling and rising according to information on the trade war between Washington and Beijing to end in a scattered order. The Dow Jones Industrial Average gained 0.39% to 25,579.39 points. The Nasdaq, with strong technological color, had yielded 0.09% to 7,766.62 points and the broad index S & P 500 had taken 0.25% to 2,847.60 points.

The resurgence of a relative optimism is due in part to the announcement Thursday evening by President Donald Trump that he will have "soon" a telephone conversation with his Chinese counterpart Xi Jinping, said Patrick O'Hare Briefing in a note .

The chief advisor to President Donald Trump on trade, Peter Navarro, said Friday that trade negotiations with China "go ahead".

Navarro, however, accused Beijing of "slashing its prices and devaluing its currency by 12 percent" in order to thwart tariffs imposed by the Trump administration.

He also estimated that the US Central Bank needed to cut rates by three-quarters of a percentage point by the end of the year.

For the advisor, "the scenario to follow" is that "the Fed drops its rates by 50 basis points in September and another 25 points at the end of the year."

The Deere tractor manufacturer took 2.6% despite quarterly results below expectations.

On Friday, the US 10-year Treasury rose to 1.542% and widened somewhat with the return of the coupon at 2 years (1.501%). It was the reversal of the curve between these two stocks that caused the market to tumble on Wednesday, a phenomenon that is considered a precursor to a recession.
