The Dow Jones index advanced by 0.20% to 33,875.40 points and the S&P 500 by 0.09% to 4,137.04 points, while the tech-dominated Nasdaq gave up 0.29% to 12,037.20 points.

"It was a mixed session, mainly due to the anticipation of a very eventful week in terms of corporate results," said Peter Cardillo for AFP, Spartan Capital Securities.

"And everyone's eyes are on the technological results to come," he added.

The first-quarter accounts of Alphabet (+0.82% at the close on Tuesday), Microsoft (-1.40%), Amazon (-0.70%), Meta (-0.05%) and Intel (-2.11%) are expected on Tuesday and Wednesday.

The week began with the quarterly accounts of Coca-Cola, which posted growth in volume sales despite its price increases, which it intends to continue in 2023.

The maker of Sprite and Fanta posted a 5% increase in earnings per share excluding special items, a figure above expectations.

The share of the Atlanta group up in the first part of the session ended slightly down 0.16%.

Results from rival PepsiCo are expected Tuesday along with those from General Electric, Raytheon, General Motors, UPS and McDonald's.

"This will be a decisive week in terms of corporate results. Any disappointment could turn the tide from the stock market," Cardillo warned.

Important macroeconomic news is also on the menu for the week.

Among a host of indicators, the most watched will be the first estimate of Gross Domestic Product (GDP) on Thursday where growth in the world's largest economy is expected to slow in the first quarter.

In addition, in Europe, the first estimates of growth for the first three months of the year for Germany and France are also expected, due on Friday.

Friday will also be published PCE inflation in the United States for March, favorite measure of the US central bank (Fed) to gauge the rise in prices.

Investors' attention to the indicators will be heightened as the Fed prepares for a monetary policy meeting the following week.

Markets are increasingly believing (at 90%, according to CME's futures) a further rate hike of 25 basis points.

But, at the same time, "there is also concern about the fallout from recent banking difficulties that could slow the economy," said Art Hogan of B. Riley Wealth Management.

In the bond market, yields on 10-year Treasuries fell to 3.49% from 3.57% at the previous close while two-year yields eased to 4.11% from 4.18%.
