AMD gains on Truist Securities' bullish upgrade

(Updates before market open)

Aug 26 (Reuters) - Wall Street's main indexes were set

for a subdued open on Tuesday, pressured by a rise in

longer-dated Treasury bond yields as President Donald Trump's

decision to fire a Federal Reserve governor renewed concerns

about the central bank's independence.

Investors also awaited Nvidia's ( NVDA ) results and a key

inflation report later this week for more insight on artificial

intelligence and interest rate cuts - the two big themes behind

recent market gains.

In an unprecedented move, Trump said he was removing Fed

Governor Lisa Cook over alleged improprieties in obtaining

mortgage loans, prompting investor unease about what it could

also mean for the outlook on monetary policy just weeks ahead of

the central bank's meeting.

Trump's action is likely to face legal challenges but, if

successful, it would let him nominate a new member to the Fed's

board at a time when he has called for lower interest rates.

"Before there were only been words and threats. Now the fact

that an actual decision has been implemented, that has garnered

the attention of the investment community more than before,"

said Peter Andersen, founder of Andersen Capital Management.

Despite lingering inflation pressures, traders have been

pricing in a 25-basis-point interest rate cut for September,

encouraged by dovish signals from Fed Chair Jerome Powell, data

pointing to labor market weakness and the likelihood that Trump

nominee Stephen Miran could fill up a recent central bank

vacancy.

"It is a very challenging defense to argue for a rate cut

currently... because the economic data does not uniformly

indicate that the economy is under great pressure and warrants a

cut," Andersen said.

Key upcoming inflation and jobs reports could prompt

investors to reassess rate-cut expectations.

At 08:48 a.m. ET, Dow E-minis were down 43 points,

or 0.09%, S&P 500 E-minis were down 4.75 points, or

0.07%, and Nasdaq 100 E-minis were down 20.5 points, or

0.09%.

U.S. 10-year and 30-year Treasuries

also fell and the dollar declined against major currency

pairs. Bond yields move inversely to prices.

Nvidia's ( NVDA ) results on Wednesday will be a major catalyst for

U.S. stocks that have rallied over the past few years on the

potential earnings growth from AI. Investors will also look for

details on how the recent revenue-sharing deal with the U.S.

government could impact forecasts.

The AI enthusiasm has also pushed up valuations of Wall

Street's benchmark S&P 500 to above long-term averages,

heightening the risk of a selloff in case the chip giant falls

short of market expectations.

Nvidia's ( NVDA ) shares were marginally higher in premarket

trading.

Advanced Micro Devices ( AMD ) gained 2.6% after Truist

Securities upgraded the chip stock to "buy" from "hold".

Interactive Brokers ( IBKR ) rose 3% as the trading platform

is set to join the S&P 500 before markets open on August 28.

EchoStar ( SATS ) jumped 72% after telecom giant AT&T ( T )

said it has agreed to buy certain wireless spectrum

licenses from the satellite communications firm for about $23

billion.

Meanwhile, data showed new orders for manufactured capital

goods increased more than expected in July. Investors will also

focus on remarks from Richmond Fed President Thomas Barkin.
