General question on Premarket. I've been trading part-time for about a year now so forgive me if this is a naive question, but here's what I don't get with premarket. I'll go to bed with a stock I want to trade the next day in mind, price targets, right. I wake up and the price target was reached while I was asleep. Then say futures are up, right, well I can't tell how much that optimism is already baked into the new price and how much there is still room for the stock to go up. Same problem in reverse if I'm short-biased, but the stock went down overnight. Seems often like if there was a big spike in premarket there's a quick profit-taking from about 9:30-9:40, then the stock will behave more normally, but apart from that, I just can't figure out how to cope with premarket shifts? Feel like if pre and post market didn't exist, my plan would always be clear to me. Any rules of thumb or general wisdoms would be much appreciated.
