(Reuters) - U.S. stock index futures were subdued on Thursday, as investors paused after Wall Street's strong performance in the previous session and awaited economic data, more corporate earnings and remarks from President Donald Trump later in the day.

At 5:20 a.m. ET, Dow E-minis were up 12 points, or 0.03%, S&P 500 E-minis were down 10.25 points, or 0.17% and Nasdaq 100 E-minis were down 103.5 points, or 0.47%.

The S&P 500 and the blue-chip Dow logged their sixth session of advances out of seven on Wednesday, with the benchmark index notching an intraday record high for the first time in over a month.

In premarket trading, AI darlings Nvidia dropped 1.8% and Microsoft dipped 0.7%, while chip stocks such as Advanced Micro Devices and Broadcom slipped 0.8% each.

Uncertainty about Trump's trade plans prevailed as he said tariffs on imports from Canada, Mexico, China and the European Union could be announced on Feb. 1, although analysts expect April 1 to be the date when major tariff plans will be unveiled.

All eyes will be on Trump's appearance at the World Economic Forum in Davos at 11:00 a.m. ET.

"One new area of interest may be the international tax code, where he could potentially tariff (countries) trying to enact the (Organization for Economic Cooperation and Development's) Global Minimum Tax - clearly something on the mind of his tech industry sponsors," said analysts at ING Bank.

Trump pulled the U.S. out of the OECD tax deal on Monday. Tariff imposition could threaten a global trade war, upside price pressures and slow down the Federal Reserve's pace of monetary policy easing.
