i guess there are several explanations for rise cuz. One is greed. Baggies just jump on any bus that is moving. They have no idea where the bus is going they just heard it was somewhere good. Another is bad DD. They look at things like the size of the heart health market and just assume they can get a piece of it without even thinking about how. They also fail to look at managements track record and their abilities and resources available to execute. What is amazing to me is their inability to change direction. Making a bad buy is one thing, holding on to it to prove you will go down with the ship just makes no sense at all.
