EDE

When you keep announcing good updates, investors get good-update fatigue.  The only time when there will be a dramatic leap is when a big company pounces on it with the intention of taking over the company.  Today, there was a small jump and then it settled back to nothing.

In my case, rather than buy EDE, I prefer to buy TAS where it is even more undervalued, relative to EDE.  I have been topping it up but in small and infrequent doses.  If someone wants to sell their TAS for a good price, I am happy to oblige.
