Sell @ $0.41.
Sold all, no more left. Sudden buy up today.
I strongly suspect it's due to their Shares Buy-Back. FY (Aug) results will likely be out in B-Oct and if I'm not wrong, Shares Buy-Back cannot be done within the 30-Days period before 1H and FY Results announcement. If I'm correct, then they're likely to be doing a last 'push', to use up their 10% (usual mandate) and at the same time, make it an incentive for Warrant13 holders to convert (Conversion price = 32ct) as they can then sell for a profit or for the coming 3.3ct dividend.
If so, then my next action would be to patiently wait for prices to correct back within the 30-days period. If I get to buy, then make sure i sell again before it goes xd. After that, will likely have another opportunity before Warrant13 expires on 27-Sep-13 and next FY results announcement. 🙂

I was wrong! Shares Buy-Back Vol = 551,000 @ $0.39. Next suspect is Fidelity who's holding 5% as of 14-Aug. Last suspect would be Traders. Let's see how the Vol & Price behaves in the follwing days.
Will try to buy back again if it drops back.
