Don't panic Mr mannering!! with a company with this much speculative 'feel good' factor surrounding it for the foreseeable? future, I'd be more than / very happy if it retraces (or is driven) down past the £1 mark as I need to top up.
I nothing other than your average PI, but I do believe what rumblings I hear from my mates who do this for a living coupled with what I see on the chart, ie: the general feeling is this is still good value at today's levels and any retrace has been met with a rally of institutional buying.
