So what's it like having Trump as president??

Truthfully, it's kind of hard to tell that he is president. His staff is quite anemic, and they struggle to craft actionable policy. Not to mention that even with his party controlling congress, they've failed to deliver on several major points. He hasn't been able to do very much. At least on a day to day level. If you're playing the market it's a rollercoaster. You can probably make money in the short game if you just wait for him to say something stupid and then buy stock right after and then sell it after he goes quiet for a while.
