Trump tweeted this morning that the stock market is up 25% since the election. He also said we need massive tax cuts so that the stock market will go up further by leaps and bounds. The market is high, but we can get it higher.

From Trump's announcement speech in 2015.

We have a stock market that, frankly, has been good to me, but I still hate to see what's happening. We have a stock market that is so bloated.

Be careful of a bubble because what you've seen in the past might be small potatoes compared to what happens. So be very, very careful.
