Puttick has been a constant seller since at least as far back as 2012 where he was selling decent amounts for around $1. Put me off a bit when I first entered at $1.35 and caused me to sell down only for the price to take off on me.
So now I try to ignore Puttick's trades. If the other directors got in on the action I would get concerned.
Hopefully the interim will be respectable. The chart has been holding relatively firm despite the jittery market
