Too many small holders worried that they have spent the rent and will have no where to live so have to sell out. Its also getting played down a heap. Something that i find interesting though is earlier in the week there were large holders (Top 20 holders) putting sale orders in the pre-open auction then pulling them before open. I think they are attempting to bring the price down to load up on some cheaper shares. Could also be that they want to get their fill as they know something big is going to be announced that we all don't know about.
