(Reuters) – The New York Stock Exchange opened up on Monday, investors hoping for a more measured approach to the customs duties of the Trump administration, whose commercial policy has changed the markets in recent weeks.

In the first exchanges, the Dow Jones index earns 339.12 points, or 0.81% to 42,324.47 points and the Standard & Poor’s 500, wider, increased from 1.08% to 5,728.77 points.

The Nasdaq Composite takes 1.49%, or 265.14 points, at 18,049.19 points.

A series of information reported by the media during the weekend, according to which the US administration is likely to exclude a series of sectoral customs rights when implementing reciprocal measures scheduled for April 2, supports the feeling in the first exchanges on Monday.

The American president had already suggested on Friday a certain flexibility concerning a new series of customs duties having to enter into force next month.

But after a month of strong volatility of stocks, obligations and currencies due to the trade policy of the American government, analysts remain on their guard.

“It is very difficult to design a structural strategy,” said Chris Weston, research manager at Pepperstone.

The macroeconomic data expected this week in the United States, in particular the price for personal consumer expenditure (PCE), will therefore be followed closely to determine the orientation to follow.

The preliminary figures The PMI index of S&P Global, published later on Monday, should also indicate a slowdown in activity in the manufacturing sectors and services in the United States in March.

“Trump has shown how unpredictable it is, while the data could strengthen the idea that the American economy is losing speed. A new risk aversion cycle this week is not to be excluded,” warns Charalampos Pissouros, analyst in the XM broker.

At the values, Super Micro Computer lost 2.5% after Goldman Sachs lowered his recommendation for “purchase” to “neutral”.
