Tinker that is one of the great things about Tower that it hasn't been diluted to hell. The recent private placing shows exactly what confidence people have in the company and if you follow that with the other strikes around the Albertine then we could be onto a seriously undervalued stock.
It was very positive that the Chairman actually took the time to respond personally to you as he could have quite easily palmed it off onto someone else.I'm not sure about the amount of shares available in the market but it does tend to move quickly with a little volume.When positive news is released it could show a good gain as you say.
