Has The Market Ever Acted in This Way Previously

When I say acted this way, I’m saying the radical changes over the past week from deep red to high green or vice-versa. Does anyone recall the market transition from 2.5% in the red to into the green? Or starting day down 1.5% to end being up over 1%?

I’m all set, but I’m newer (3 years in the market) and find these radical shifts wild.
