New York (Reuters) – The New York Stock Exchange ended up on Tuesday in a context of uncertainty still high about American customs duties, which weighed in particular in the consumer and health sectors, even if the solid quarterly results of banks have brought a clarification.

The Dow Jones index sold 0.38%, or 155.83 points, to 40,368.96 points.

The wider S&P-500 lost 9.34 points, or 0.17%, at 5,396.63 points.

The Nasdaq Composite fell on its side from 8.32 points (0.05%) to 16,823.17 points.

Raising at the start of the session, the main Wall Street indices finally fell, illustrating the climate of uncertainty in the markets while US President Donald Trump multiplies commercial announcements.

Federal documents registered on Monday evening show that the Trump administration has opened investigations into imports of pharmaceuticals and semiconductors, suggesting possible customs duties.

Most analysts say they expect the markets to remain volatile as long as there is no more clarity on taxes actually imposed by Washington.

Donald Trump suspended last Wednesday, a few hours after their entry into force, large so-called “reciprocal” taxes on products from dozens of countries, including the main trade partners of the United States. These measures had been released a week earlier.

The American president also pointed out potential exemptions with regard to 25% customs duties levied on automotive imports.

Noting that “the quarterly results are rather good”, Ross Mayfield, Baird strategist in Kentucky, especially stressed that the market was “struggling” with commercial uncertainties. “It is the only catalyst that is important at the moment,” he said.

While the quarterly results season has just opened, business leaders are expected to be cautious in their forecasts, even reluctant to communicate, in this commercial context making a vagueness over the prospects.

The solid quarterly results of large American banks have brought the financial sector, like Bank of America, in sharp rise on Tuesday after results in the expectations over the January-March.

On the other hand, the health sector has declined, weighed down by the Merck & Co and Johnson’s withdrawal, whose disappointing quarterly sales of medical instruments made investors forget a profit higher than the expectations in the first quarter.

In addition, the Dow Jones was sealed in particular by the decline of 2.4% of Boeing after Bloomberg reported that China asked its airlines to no longer accept delivery from the American group in response to 145% customs duties imposed by the United States.
