yep depends if just a day or two , or weeks hopefully the former, as not really a huge amount of shares in issue and im sure II will not be selling all their shares considering whats on offer here!
i would doubt it will make any difference to the price. sure II will hold for bigger gains and then the 1million shares for the public will not make much difference especially if in a upward trend in the share price.
if an II was to sell it would suppress the share for a bit maybe. just IMO
