It's mind-boggling that the US markets have had so much faith in Trump. Puts paid to the notion that the US economy was really recovering. We all know the "recovery" was nothing but easy money from the Fed.
The other major risk is the debt ceiling which expires on the 15th March. I can't see Trump getting a trillion dollars for infrastructure and more for defense in this environment. But apparently the market doesn't care.
Around the same time the US should raise interest rates too and that should re-focus the market on the reality of things. The discontent/hatred that the Republican party has for Trump is going to make everything and anything he wants to do very difficult.
