Also means we should all be a bit careful of drawing easy conclusions if it starts ticking up though... off the back of a 100m share purchase it may look very strong and inevitable that it will go up... but there is a certain amount of short-term risk of a pump-and-dump attempt by whomever just made that buy.
I'd exercise due caution buying on the upward before 18th... it may turn out just to be a ghost.
