Hi Tod, on Tuesday there were 624,371 shares traded before close and there was a 626,894 share trade just after close. So for this day at least the scenario you describe doesn't fit. Strange to say the least.
I have always felt that as tightly held as everyone here knows LWLG stock is, that there were always enough shares available in the tradable float to accommodate the volume over the past couple of weeks. I also believe what someone else on this board mentioned over the past few days (it may have been you Lewrock, I can't recall) as the likely explanation for these late day "prints" at the market close, or just after the bell: that being that some big orders were given to a broker for x amount of shares, designated not to exceed a "limit" price. These type of orders are then "worked" throughout the day by the broker and whatever amount of shares they were able to execute that day are reflected at the the close, or just after. I feel very confident that this is what has been happening. That being said, the similarity in the size of the trades has been somewhat interesting. As always, I could be wrong.
