Look, the way I see it is:
- if it is not a pump, the buyer must know that the news is not going to come out real "soon", or it will be painfully obvious what's going on! Probably not this week or next week. And mind you, the news must be incredibly good to warrant such volumes as we've seen the last week or so.
- if it is a pump, then you have to look at the average buy price over the last week or so, because the only reason for pumping is to make $$$. I'm guessing the average buy price is about 2.8c over the last few huge volume days. Then you ask the question, how much is a good profit margin for these guys? 20%? 30%? Based on this, you do not sell until at least about 3.5c - 4c.

Either way, you don't sell at the current price of 2.9c, that's for sure!
(For the record, I am guessing that it is not a pump, and that we are probably looking at a hostile takeover. Buyer is buying in the open market to take advantage of the negative sentiment around this company.)
