Probably more telling than no insider sales....is that no insider purchases have been documented either. So....either insiders are buying shares and not reporting their trades or they are not buying at all. Why? If insiders truly believe in this company and the ZincAir technology why hasn't one insider stepped up and shown his/her faith in this company and bought up these shares and reported it on SEDI if as allenjames would have you believe the shares are way undervalued?
I think everyone knows the answer and if you don't just think about it for a few minutes and I am sure it will come to you.
