Futures up: Dow 0.43%, S&P 500 0.48%, Nasdaq 0.56%

Jan 21 (Reuters) - U.S. stock index futures firmed on

Tuesday, as investors assessed newly elected President Donald

Trump's executive orders on issues including energy and

immigration, while awaiting his first move on trade policy.

President Trump did not immediately impose tariffs on Monday

as previously promised, but said he was thinking about imposing

25% duties on imports from Canada and Mexico on Feb. 1 over

illegal immigrants and fentanyl crossing into the United States.

Investors took some comfort that Trump did not lay concrete

plans on the universal tariffs and additional surcharges on

close trade partners that he had pledged during his campaigns.

Brokerage Goldman Sachs lowered its forecast for a universal

tariff this year to 25% from about 40% seen in December.

At 05:39 a.m. ET, Dow E-minis were up 189 points,

or 0.43%, S&P 500 E-minis were up 29.25 points, or 0.48%

and Nasdaq 100 E-minis were up 120.75 points, or 0.56%.

The quarterly earnings season will also pick up this week,

with reports from Prologis ( PLD ), 3M ( MMM ) and DR Horton ( DHI )

among others, due before markets open.

Futures tracking the domestically focused small-cap Russell

2000 index added 0.7%.

Automakers General motors and Ford that have

supply chains spread across the continent edged up 2.1% and

1.6%. Elon Musk-led Tesla added 2.3% premarket trading.

U.S.-listed shares of Chinese companies Xpeng and

Li Auto added 6.8% and 5.8%, respectively on no signs of

imminent surcharges on Chinese goods.

Markets have been sensitive to any reports on Trump's tariff

policies on concerns it could spark a global trade warand fresh

inflation pressures.

"Tariffs mean a stronger U.S. dollar due to higher import

prices and weaker global growth, no tariffs means stronger

global trade and a more robust global growth backdrop," said

Kyle Rodda, senior markets analyst at Capital.com.

"Just like the first Trump administration, the markets are

highly sensitive to headline risk, especially as it relates to

trade wars."

During the first year of Trump's first administration, the

S&P 500 rose 19.4%, while during the entirety of his

first term, the benchmark index rose nearly 68%, but saw bouts

of volatility, stemming in part from a trade war Trump fought

with China.

However, inflation is still above the Federal Reserve's 2%

target, stoking worries that Trump's policies could delay the

central bank's pace of monetary policy easing.

Economists see the Fed leaving borrowing costs unchanged

when it meets next week and traders see the first interest rate

coming in July, according to data compiled by LSEG.

Oil stocks Halliburton ( HAL ) rose 2.2% and SLB

climbed 1.9% after Trump declared a national energy emergency to

accelerate permitting oil, gas and power projects.

Prison operators Geo advanced 3.2% and CoreCivic ( CXW )

rose 7.8%, after Trump declared a national emergency on

illegal immigration at the U.S.-Mexican border.

Nuclear stocks Oklo ( OKLO ) rose 6.4% and Vistra added 6.3%

as energy secretary Chris Wright said he plans to prioritize

domestic nuclear energy production.

Apple ( AAPL ) fell 1% after brokerage Jefferies cut its

rating on the iPhone maker to 'underperform'.
