RE:Should I sell some or should I let it run? (Hold)When Ivanhoe reached about half of the value of my portfolio in November, I sold off about 20% of my shares for a mere 300% gain. I certainly regret that decision now that it's up another 50% since then. Having learned my lesson, I replaced those shares at a higher price and plan to hold them until at least the end of the year an I expect I will still have a sizable position in the company for at least the next ten years. I have owned plenty of mining stocks, including some that have 10- and 12-baggers. However, none of them have had as much going for them as Ivanhoe. This company truly is unique in it's resources and execution.
