The Republican tax plan called for broad changes to the U.S. tax code, including slashing the corporate tax rate and reducing the number of tax brackets for individuals.

“Everyone knows it is a long shot, there is not a bunch of money trying to get ahead of this,” said Phil Blancato, CEO of Ladenberg Thalmann Asset Management in New York.

“Unfortunately, I don’t think anyone believes this is going to go through; it is a wait and see opportunity.”

President Donald Trump tapped Fed Governor Jerome Powell to become head of the U.S. central bank, promoting a soft-spoken centrist to replace Janet Yellen when her term expires in February 2018.
