You're poorly informed if you think any 6 month move of the stock market can be attributed to Trump policy.   It was moving in a positive direction for over 6 years.     The only way Trump policy can move the market at this point, is to promise more income through tax reduction to a small minority of American ownership.

See if you can follow this.  A corporation could make ZERO changes to process, marketing, sales... yet go up in Market value based only on short term gain due to lower tax's on realized gains.  NO value added.

This is the problem with American investment and is has been for years.   Stock prices are NOT a measure of productivity/value: they do NOT reflect the true value of a corporation at any particular point of time.   Market's are moved by investor sentiment and it can be very short term.*

*Do you know anything at all about superfast trading?  That has ZERO concern for value and is totally based on price movement for a period of milliseconds.
