You know better than that. We have had this discussion many times. I made millions and sold all but $500k worth. I am not sure how much those $500k worth originally cost me because I daytraded on the way up and on the way down. I held onto those $500k because, while I expected the stock to drop, I also expected that it would recover and I wanted to be part of that. When a company is just starting out, always expect that the run up it temporary and it will take a minimum of 6 months before they can get anything going. If they don't have a marketable product, expect longer. I have posted many times that I expected 2 years. It has taken much longer.
As for your question, I sold some shares before I posted a chart showing the stock above the bollinger bands and a warning to watch the volume - it was a hint that the stock should fall and look for a support level. I also explained this a few times as people called me a hypocrite for selling some shares when I told them that my goal to permanently reduce my shares by 10% won't likely come until after .02. It may end up .01 or it may end up .08 depending on the charts, but .02 is where I will consider my initial sell (permanent sell). I also have said many times that my goal is to own 50% very long term - years or maybe even decades. In that time, the stock should rise and fall. When it falls, I expect you will post that I held my entire position and rode it down. That again won't be true.
