Spy 3 day weekend

A coworker of mine asked what happens after a 3 day weekend do market go up or down? Well last 4th of July SPY closed -0.18 doesn’t mean it will happen again of course. For fun I looked up the last year and the answer is we close red 60% of the time. If you guys and gals have any requests for charts leave a comment below would be happy to help. Be safe out there HAPPY 4th OF JULY
