When to sell is always one of the hardest things to do. However, I like the proverb of letting your winners run and sell your losers quickly. TA is never perfect but can give us some good hints about when to sell. There is a website I have been using lately that gives simple buy and sell points on canadian stocks: Canadabulls.com When they post a sell signal, you may want to pay attention and sell at least a portion of your position.
However, for ZEN, my plan unless fundamentals change is to sell my first shares around $10. I will let the rest ride thru to take over or production and take the dividend!
As for the disbelievers, I can only say that I am honest and I never pump to dump. If I take alot of credit for this one, I also have to live with my other picks that did not do well. So even though it feels great to have such a huge winner (I first recommended this stock at 38.5 cents when I started this hub), the market is about making money, not about being right. In this case, I was lucky to do both.
