NEW YORK, April 28 (Reuters) -

The S&P 500 closed a choppy session nearly unchanged on

Monday, weighed down by megacaps as investors awaited several

catalysts including key economic data and earnings from some of

the largest U.S. companies.

Megacaps Nvidia and Amazon ( AMZN ) were the

primary drags on the benchmark S&P 500 index and also served to

keep the Nasdaq in check.

The Wall Street

Journal reported

on Sunday that China's Huawei Technologies was preparing to

test its artificial-intelligence processor, which it hopes can

replace some of Nvidia's ( NVDA ) higher-end products.

Of the so-called Magnificent Seven heavyweight companies,

Amazon ( AMZN ) is scheduled to report quarterly results later this week,

along with Apple ( AAPL ), Meta Platforms ( META ) and Microsoft ( MSFT )

. Apple ( AAPL ) and Meta both rose to help counter the declines

in Nvidia ( NVDA ) and Amazon ( AMZN ).

In all, 180 S&P 500 components are set to report earnings

this week, and investors are likely to closely monitor how U.S.

President Donald Trump's new tariffs could affect future

profits.

"We're going to get four of the Mag 7 reporting this week

and so this is a very important earnings week," said Jack Ablin,

chief investment officer at Cresset Capital in Chicago.

"I'd love to hear any kind of forward guidance and it

will be really interesting to hear some of these CEOs talk about

how they're planning to navigate the potential trade war."

According to preliminary data, the S&P 500

gained 3.43 points, or 0.06%, to end at 5,528.37 points,

while the Nasdaq Composite lost 17.35 points, or 0.10%,

to 17,365.59. The Dow Jones Industrial Average

rose 111.29 points, or 0.28%, to 40,224.79.

Though first-quarter earnings from S&P 500 companies are

expected to climb 10.9% from a year ago, according to LSEG data,

many firms have warned of the uncertainty caused by U.S. trade

policy, with some cutting or completely pulling forecasts.

Of the 179 S&P companies that have reported, 78 had negative

earnings outlooks and 32 had positive forecasts, for a 2.4

ratio, slightly below the 2.6 in the year-ago period, LSEG data

showed.

Investors will also parse important economic data,

including the personal consumption expenditures price index and

a flurry of labor market data culminating in the monthly U.S.

payrolls report on Friday.

A gain in Boeing ( BA ) shares helped keep the Dow in

positive territory after Bernstein raised the aircraft maker's

stock rating and price target.

Trading was choppy after stocks opened firmer, with the

S&P 500 and the Nasdaq briefly touching their highest levels

since April 2, prior to Trump's tariff announcement.

Markets have stabilized somewhat in recent weeks on optimism

over potential deals between the U.S. and its trading partners,

especially China.

However, a lack of clarity on Sino-U.S. negotiations has

kept the market sensitive to any developments. The S&P 500

remains more than 10% below its February record high as

investors look for clues on the extent of any tariff damage.

A majority of economists polled by Reuters said the risks of

the global economy slipping into recession this year were high.

Spirit AeroSystems ( SPR ) shares advanced after Airbus

reached a deal to take over some of the company's

plants.
