I think the accumulation is smart, there is a lot of punters with their stop losses on since GFC. The one great thing the spook of the GFC allowed was "people" can manipulate the market for their own gain far more easier.
You can sell down on a thin volume day, trigger a heap of orders on the sell line and then pick them up. $1.6 mill is a lot of money in todays market and given the history of the company I would think a lot of folks did some serious DD and has some sort of assurances.
Time will tell, but I would suspect in the short term we will know......
