I think that's a trap set up by the deep state which control the US through their representative Donald Trump.
1. They push up the stock market by passing the bill of "Tax Reform".
That bill will increase the national debt to a new high. In another word, borrow money to benefit rich people.
2. Stock market is at the historical high, once it collapsed, innocent people will suffer a great loss. I think that's a plot to blow up a bubble to loot public's retirement fund (401 k) and their savings.
Watch the chart. You don't have to be expert to see how big the bubble is. Yet they blow the trumpet for it.
