The terrorist attacks in Paris it's a horrible situation. The last thing most people are thinking of right now is the market. However, it will be in the forefront come Sunday night for those who make a living from the market. As a possible point of reference below we have the SP500 and VIX charts from the 9/11 incident and the Boston marathon bombing in 2013.
9/11/2001 terrorist attacks

We have no idea how the Paris attacks play out for the market next week, these are just possible road maps.
