Trump made it clear at start of his presidency he would destroy the value of the $ in order to make american companies more competitive. Like it or not, that is the economic plan for the next 3 years, or longer if he is re-elected.
INHO, by next year the tax cuts will have ruined the american economy by severely increasing inequality. That is one of the premises of the book I helped write last year and that will be printed in March. Not pushing it, but if you read it, will understand the economic cycle, and we are at the euphoria stage, followed by contraction, financial crises, a bottom in corporate profits, then rebound.
Predicting the exact top can bankrupt you, look at me! Have now lost half my money shorting the market since brexit, when I went fully margined short and had my head handed to me!
Bottom line: Euphoria gives way to fear eventually, getting solid signs of top, but tops take forever to form. Watch for at least a 2% drop followed by another rally to short heavily.
