Silly games again?

Once again we see some desperado (el bastardo) jumping down across the spread, with a trade of $546 only, but dropping the share price by 0.5c

That has now happened on several occasions over the last few weeks. I wonder who is playing silly buggers, and why?

Is it really somebody who is so desperate to get out of ACB that they're happy to jump the spread like that? But if so, why only that small amount, when there is still plenty on the buy side at that price?

'Tis a bit of a mystery - and a frustrating one at that...!

Bastards.
