1. Never sell because the price looks high. For example, if you look at it from 10 to 20, what should you judge at this time is what is preventing them from 20-50?
2. Similarly, don't buy directly because of the high price in the previous period and a lot of drop. The decline is justified.
You know, your first reason is one way to think for which I haven't considered very much. Not like I'm completely ignorance of the fact that, there are those factors that tends to hinder a directional growth pattern but, should it be used for a determinant as to why you shouldn't sell haven't been much of a plan for me. Its really cool to have shown this part to me and I hope someone else do see reasons too.
Again, I doubt investors don't do some speculations themselves. What's really the difference?
As an investor, you've hot yo speculate on not just when you should be expecting some returns investment but, the factors that could result in its boom.
