The professional tend to say the opposite, in that it is best to let winners run but cut off the losers quick. I guess that's why retail never really get the 10x plus stocks, they always sell them at 100% profit because they think that's good enough. Except then they lose it all because they hold losers forever. Should be the other way around really, winners should be held forever and losers should be quickly sold. Of course, when the winners start to become the losers then they should be cut off as well. Fairly easy to tell when that happens, the numbers reported begin to slow/deteriorate, the excitement fades and prices stagnate/decline. But just like you shouldn't catch falling knives, you shouldn't sell randomly during an uptrend simply because you're happy with your little bag of profits

Just my view of course... see you at $10, this rally is still only getting started
