Went from 3.5c in July to 17.5c in August (market cap of over 500mil if scaled for 60% share) and people are crying that Klaus/Airguide have let them down! 'This was supposed to climb forever! It must be some illegal conspiracy! ASIC will hear about this! (no they won't)' Even if Klaus didn't sell a quarter of his shares, AVZ would of very likely come down just as it has due to its colossal and rapid SP rise.
So what happened? The fact remains that a lot of people jumped in late and got hit with a retrace and instead of learning from it, now need someone to blame. More rational folks are tell them that the fundamentals are solid (multiple record drill intercepts). Given time, more drilling and a much needed change of hands from the masses of short term speculators to longer term investors, AVZ will pick up again.
Here is a nice post showing a quick comparison of AVZ with PLS/GXY/BGS announcements. The numbers speak for themselves (hole 7 is not even included there).
