R59, I appreciate that valuing a stock isn't easy, and
can change hugely based on market conditions and other things. However once you do your dd, and decide a stock is undervalued, I believe that's in and of itself, saying you have some price target, or at least a price target range. Otherwise it becomes a total guess when to sell, and is purely gambling, the longer you keep it. I believe the goal of a trader should be to make the market as much of a science as possible, knowing you will never hit the top on a stock, and will make plenty judgement errors along the way.
