I am not sure if it is a coincidence or not, but AMS was one of the stocks reviewed on David Kochs the Call on Ausbiz a couple of days ago. The guests were very complementary and that afternoon and today (at least last time i looked) the share price has popped. I like this stock, it is similar to AD8. I can't remember the names guests on the Call but they thought that anything below $0.50 Was good for a buy.
I don't own AMS, but is on my watch list.
