The other problem I had with GCHT - was that it moved before a news announcement... like 20 - 30% nothing subtle.. so clearly someone already knows what's going on.
That said... if they signed a 3/4 of billion order or 2 then I would shut up and buy like everyone else.
Basically, this is a new varient of a technology and people are wondering if it's going to come together or not.
There's lots of recommendations on the CGS boards - some are more speculative than others. So there is no need to take this gamble and most don't.
