day traders or accumulation?

I know the word "accumulation" gets thrown around a lot - but if you analyse recent trading (last 2 days especially) it seems a bit strange.

1) It seems like the morning has meant heavy buying, with small selling in the afternoon.

2) Everytime the SP gets to 4.2/4.1 it gets smashed down with huge sell volumes, that then dissapear after.

A lot of the morning trades will be day traders hoping for looming announcement, but the way everyone refuses to let it run past 4.1 is uncanny.

So, it could be day traders that then close their positions before days end, but its some pretty heavy buying in the morning compared with what is sold down in the afternoon.

Seems like someone wants every share they can get at 4.0c or below.
