Actually, you made it a conspiracy story in your original comment,
"Yeah someone trying to push it down". That language speaks to manipulation, which implies conspiracy.
In reality, we saw 2 x block trades today for a relatively enormous combined volume of ~37.5m shares, which were both matched on block trading platforms (i.e. neither of these two trades were placed in the open depth queue). Furthermore, the first trade (20m) went through before the market opened. The non-block trade remainder of today's volume totaled 1.35m shares (ASX trades only). And all of this allegedly manipulative activity resulted in... wait for it... a 0.1c downward move in the SP!
In reality, those two block trades (37.5m) were simply one (or two) large sellers finding one (or two) large buyers. If there was a true desire to drive the SP down, then the sell orders would have been placed in the open depth queue during trading hours and some panic would have almost certainly ensued. None of that happened.
If you're gonna make wild and unsubstantiated statements, the least you can do is own them.
