I suspect you don't understand capital gains tax and the two limits. Lots of reasons to sell at different levels depending on the time of year. If you are all in or all out with ONCS, I suspect you should get a real compensation career with some stability.
Just curious, why do you care. You are playing the top or bottom. Based on your comments you win either way. If your life revolves around ONCS and have all this time on your hands, I think you are the "fool" investor. It's called diversity on 10 or 20 stocks or have a money manager. I'm not trying to sound bad, I'm just confused with your goal.....Comment?
