Early that morning, The President refused to sign the $1.5 trillion Omnibus Spending [Bill.In](http://Bill.In) the wake of the tariff spat that he had also triggered the day before with China, markets remained down for the duration of the day, until, rather unexpectedly, he signed the bill that SAME day, Markets bounced slightly before close on the good news and boomed the following Monday (3/23 was a Friday) after news came out that China and the U.S. were going into negotiations.
**4/2/2018 SPY: -2.23%**

**12/4/2018 SPY: -3.24%**
A slightlytricky day, not much was going on aside from 3Y and 5Y yield curve inversion, it didn’t help that he suggested that a “real” deal with China was still uncertain.
**12/21/2018 SPY: -2.06%**
Two days after a rate hike (which greatly displeased him), the President made matters worse by actively threatening to keep the government shut down. Government shutdowns are typically very unwelcome to markets.
