Last low was 26/9/11 where the price blew out from 7c to 5.6 in a day. That signalled the bottom and the recent batch of good anns. came out not long after and the price gapped up.
The last time prices were in the 5's before that was when the price gapped up to 5.3c from 3c or so.
So technically there's nothing holding the price up at all. On the other hand, human nature tends to prefer nice round numbers like 5c.
I agree with Tweets that a big chunk of director buying would send a clear message to the market. But- and I don't blame AVB here, it's a general problem- when you've got a stash of options, why bother?
