Which is exceedingly unlikely because of the circuit breakers. A level 3 breaker is triggered after a 20% decline and halts trading for the remainder of the day.

Oh wow good point! The existence of breakers lurked in the back of my mind, but I didn’t realize the implication there. That is nice.

Not that a 60% 1-day decline would be welcome by many investors :P
