Actually if you were short going into earnings yes, but I bought when stock was about 8 dollars up after it came off it's highs with a stop limit 2 dollars above that, it came down and went up and almost initiated the sell stop, but by end of day I was up.
Unfortunately, I did re-short AZO ahead of earnings. I erred in thinking the pre-earnings rally wasn't sustainable. I have a cushion with this stock, though because I shorted it late the week before last and covered during last Monday's 600+ point drop in the DJIA. That made me too eager to re-short when the stock jumped up again. I didn't add to my AZO short today, but I didn't cover that short either. I added a small Jan 115 put position and may add to that position later this month. Fortunately, my other shorts cooperated better today, including my UPS and BNI shorts, which I covered. I'm not happy about my AZO short position, but I think there are enough reasons for me to hold it.
Congratulations to those who made money being long AZO for about a week and to those who weren't short ahead of earnings.
