Ronran - one thing worse than holding for 8-9 years and then selling at a loss, would be to sell at a loss at 8-9 years , just prior to a huge run up.  If you did sell after this long, you probably would not want to even check to see what PTSC is doing, which is usually hard to do.  Hopefully, for you and all of us, April numbers will make you want to remain a "long".
