The S&P 500 hit a record high after Trump's comments calling for lower oil prices and interest rates.
Trump told reporters he would consider talking to the Federal Reserve about lower interest rates.
The Fed is scheduled to meet next week, and expectations are that they will keep interest rates unchanged.
US stocks were higher on Thursday, with the S&P 500 closing at a record high for the first time since early December, with the latest all-time high fueled by comments from President Donald Trump during the World Economic Forum in Davos, Switzerland.
