With limited buyers in the market the climb is not as fast as one would hope but once the festive season is over I think that's the last time one would see this share trade under 400 remember the shares issued to buy Breamore sold for 405 so that should be quite a strong platform.
Since the price for Jubilee is set in the UK where it trades well over a million shares a day - these additional shares might at most have opened an arbitrage gap between our illiquid market and the AIM price for a little while. They could hardly have really had an impact on the share price. HOWEVER - issuing them in the first place shows a trend that investors might interpreted negatively - ie. pay for everything with shares.
