NEW YORK (Feb 10): US stocks hit record highs shortly after the open on Friday, a day after President Donald Trump said he would release a major tax reform plan in the coming weeks.

The biggest theme for investors is that Trump's tax plan will move quickly and he has always maintained that it is going to be very aggressive, said Uriel Cohen, founder of Alpine Global in New York.
