(Reuters) – U.S. stocks opened lower on Monday as investors sought fresh catalysts after a strong jobs report last week, while uncertainty over President Donald Trump’s policies continued to weigh.

Investors are wary about Trump’s focus on isolationist policies including travel restrictions to the United States. A federal judge on Friday blocked a travel ban on seven mainly Muslim nations.

“The market is looking for direction from the White House on policy,” said Albert Brenner, director of asset allocation strategy at People’s United Wealth Management in Bridgeport, Connecticut.

“When you see the markets pause, it signals investors are becoming more rational and are waiting to see some concrete evidence that drove the market higher after the election.”

Markets rallied sharply after Trump’s election victory in November, riding on hopes that his plans including simpler regulations, higher infrastructure spending and tax cuts will boost the economy.

However, Goldman Sachs economist Alec Phillips said in a note that Trump’s agenda presents risks as tax cuts and infrastructure funding may boost growth, but may be offset by negative effects of restrictions on trade and immigration.
