The news caused a massive selloff from $16 to $14 and triggered the circuit breaker, LOCK got halted. LOCK got halted 3 times and I shorted it at the 2nd time. I covered just in time before the 3rd circuit breaker got triggered which was a good idea. The 3rd halt lasted about 30 minutes while the 1st and 2nd only lasted in 5 minutes. When it's a massive selloff, you don't know if it will bounce or not. That's why it was risky to hold a short position during the 3rd halt and wait for it to reopen.
I locked in the profit and didn't lock back.
