TP,
I'm not sure what you mean by a 'spike'. Are you referring to the fact that the company now seems to trade in the range 18.5c-20c rather than 14c-16c? The word "spike" implies some departure from a normal trading pattern... are you sure that the 14c-16c range was the normal one? There was a "substantial shareholder" notice late last week, which seems to suggest that current prices are the norm.
