Wall Street Questions If Trump Can Turn His Promises Into Policy

It's a lot easier to say you'll do something in Washington than to actually get it done.

A number of Wall Street analysts are becoming increasingly concerned that President Donald Trump won't be able to follow through on several key proposals that he campaigned on, such as lowering corporate taxes and increasing infrastructure spending. If he doesn't, or aspects of the reforms are pared back, their outlooks would become much less optimistic.

Stocks in the U.S. have rallied more than 8 percent since Trump was elected, but all of those gains were made between Nov. 8 and Jan. 6. Since then, markets have stalled as has consumer confidence.

"[M]uch of the improvement in confidence over the past two months was certainly the Trump effect, as to be expected, but as seen with some consumer confidence indices lately, the confidence flattened out in January from the initial euphoria in December," Peter Boockvar, chief market analyst at Lindsey Group LLC, wrote in a note last week. "The same can be said for the stock market."
