The latest rally got another boost on Tuesday when Treasury Secretary Steven Mnuchin discussed the Trump administration's goal of achieving tax reform, and possibly making it effective this year. Mnuchin was interviewed at the Delivering Alpha conference, a CNBC and Institutional Investor production.
