For AEI someone keeps putting in an order with big SP since the last tick. Today they put in 0.655 bid when the last transaction was at 0.605. This has happened in the last 5-10 minutes before market close over the last couple of days. Also the order size is bigger than the several Sell orders and because of the price increase (about 50c) takes up almost top 5 Sellers. So the next in queue on the Buy side have no chance of having their order filled during the day.

I was going to take a screenshot around 3:50 when I saw the order but didn’t think this would happen again. I am going to keep my eyes open. May be nothing illegal, just me being a newbie find this interesting behaviour as this price was way beyond the highs of the day. Thoughts welcome.

On a separate note, do long term holders have any thoughts on valuation?
