Certainly, if we all knew how things will play out and aware of all of the forces therein and when they come into play, one would buy at the last low. That's not reality. Because one doesn't know if/when a partnership, buyout or early conditional approval will happen, a confirmed investor takes a position early and holds. That is my style... invest early (when the DD confirms) and hold. I don't want to miss any upside surprises.
Missling is doing just fine. If he were to do any more promotion he would be attacked by the same posters who say he's not doing enough.
Accumulate at these levels and hold!
