Jim, sorry, can't respond private. Not a member. But, yes, could be company buying back stock. I have emailed them a couple times about buying back stock or going private. To do that they would have to price it at book or more. They could be trying to buy cheap shares well below book now and then announce down the road. Good size bids keep coming in so it could also be the private investor that had a good chunk before they went dark. Lastly, it could be a newsletter or broker that discovered it, but it would seem to have more little buys instead of blocks. So my guess is company has had a couple good quarters and want it to themselves. Hope this helps.
