One thing to be aware is that while the market is closed on Friday for Good Friday, the BLS will be releasing the employment report. This is only the 11th time since 1980 that this has happened. Below is a list of all previous instances along with their performance on Monday when the market was open again.
Six instances closed down and four closed up on Monday, so on the surface this study does not seem substantial. But what is notable to me is that 7 of the 10 instances saw the market close either up or down by more than 0.75%. (Those are all circled in blue.) That shows the Monday reaction has often been volatile, and suggests risk may be elevated a bit because of this.
