I personally haven’t done very much trading over earning releases but just some observations that I have picked up is that once a stock has upward momentum quite often if there are gaps over earnings they tend to go the way the stock is moving.
I would think to do if you are trading a small universe such as the NASDAQ 100 a lot of the stocks might be reporting in the same month so you might have to end up taking signals that aren’t as strong, and then earnings might not go your way.
I’m not sure if I can help you in the way of testing that though. Also this would not be the first time observations are incorrect… :ohmy:
