Sorry the mention of 10p upset you, but one step at a time and you will see a return to placing levels and beyond (IMHO).
As for Institutional buying, the small investor was enough to take this up to 12p back in late August, and If there is one lesson we should all have learnt during this bear market it is to take a decent profit when you see one.
I don't see that perception changing in the next 6 months either, so I would trade PRO at every opportunity until sentiment changes. Ultimately fundamentals will ensure PRO heads in the right direction but we should all take the chance to bank any profits on PRO or any other stock that 'spikes' in the near future.
