I must be missing something here.
We get a brill announcement about hydrogen in China followed by very upbeat interviews with Justyn.
NRZ has previously hit 40c without any of the recent developments and yet, after the stock moved up well on Wednesday it has since tanked.
Why on earth would a Director announce selling 2m shares right now at such a critical time.
As a long term suffering investor and don't get the logic of his timing at all.
So the SP has tanked to 5.5c after such a positive development.
Don't get it.
What am I missing??
