The ups and downs of the S&P 500 since the 1950s - Part 2

In the last post about the movements of the S&P 500, we found out what happened the day after an extreme movement. An extreme movement was defined as a movement of more than 3 percent in one day. I also think that it is interesting to see what happens a week after the S&P 500 has moved with an extreme movement. This is the result:

Average: 0.01% 

Average: 0.54%
