Aug 11 (Reuters) -

Wall Street's main indexes were mixed on Monday as investors

prepared for a busy week and chip companies teetered after

agreeing to share a portion of revenue from China sales with the

U.S. under a trade policy shift from the Trump administration.

Semiconductor giant Nvidia ( NVDA ) and Advanced Micro

Devices ( AMD ) wobbled in early trading and were last

marginally higher after a U.S. official told Reuters the

companies had agreed to give the United States government 15% of

revenue from sales of their advanced computer chips to China.

Enabling semiconductor sales to China was an integral issue

in the agreement Washington and Beijing signed earlier this year

- which expires on Tuesday - and markets will keenly watch how

the latest development impacts the relationship between the

world's two largest economies.

"It's a good way for the United States government to

increase its cash and income... but a lot of people are going to

argue that this is the wrong way to go," said Robert Pavlik,

senior portfolio manager at Dakota Wealth.

"The Chinese government will probably use it as a point to

argue that they need different chips because these particular

chips might be susceptible to be reviewed by the Americans."

Markets also sought clarity on the sector tariffs U.S.

President Donald Trump had announced.

At 09:52 a.m. ET, the Dow Jones Industrial Average

fell 63.86 points, or 0.14%, to 44,109.53, the S&P 500

gained 0.84 points, or 0.01%, to 6,390.29, and the Nasdaq

Composite added 1.42 points, or 0.01%, to 21,451.44.

Seven of the 11 major S&P 500 sectors slipped, while

healthcare gained 0.6%, recovering some of the 5%

declines it had logged so far this year.

Traders took a step back after last week's rally helped the

S&P 500 and the Nasdaq log their strongest weekly

performance in more than a month.

Investors expect that the recent shakeup at the U.S. Federal

Reserve and signs of labor market weakness could nudge the

central bank into adopting a dovish monetary policy stance later

this year, fueling much of the optimism.

July's consumer inflation report is due on Tuesday and

investors currently anticipate the Fed will lower borrowing

costs by about 60 basis points by December, according to data

compiled by LSEG.

A better-than-feared earnings season brought some relief,

with BofA's monthly fund manager survey showing that buying

megacap stocks was again the most popular trade. Citigroup and

UBS Global Research became the latest brokerages to raise their

year-end targets for the benchmark S&P 500.

In earnings, Micron raised its forecast for

fourth-quarter revenue and adjusted profit, sending its shares

up 3.4%. The broader chips index added 1%.

Intel ( INTC ) was up 4.9% after a report said CEO Lip-Bu

Tan was expected to visit the White House. Trump had called for

his removal last week.

Trump is expected to meet Russia's President Vladimir Putin

on Friday to try and negotiate an end to the war on Ukraine.

Advancing issues outnumbered decliners by a 1.42-to-1 ratio

on the NYSE and by a 1.33-to-1 ratio on the Nasdaq.

The S&P 500 posted 11 new 52-week highs and nine new

lows, while the Nasdaq Composite recorded 48 new highs and 41

new lows.
