Can sp500 have two -20% draw down in 1 calender yr?

DId sp500 had two -20% draw down in one calender year?

Is this statistical significant?

It still a risk, but i guess it is a tail risk, at least very low probability. 

Even if it happened, it must driven by some other tail risk. 

I will keep eye on it, but would not bet on it.

 

Of course, the market will continue to be volatile, and there will be down days, and might be big down days.
