Even though stock was choppy and volatile it had clear highs that it could not get over even during the pre-market. I tried to get short position as high as possible to wait as long as it takes and then cash out. Yes yes, you don't short earnings winners like CAMT for their ability to spike. I know. I'd say if it spikes day highs in the first minutes of pre-market, then it's down fall all day. I was thinking of holding it overnight, but I was worried broker might liquidize position.
