There must be a reason for this. Someone with a better memory or some saved files might shed some light on what I’m getting at.
Now I’m just spit balling here, but is it possible that maybe some options old options might be coming to date and price held down for such reasons. Or something to that effect. I was lucky enough to watch close it looked like almost another 1 million shares were about to move after 4pm. Then the final close nothing it evaporates not a 1. Not sure if anyone else was watching but some 30 mill for the day,then pulled last minute/second like it mattered. As if the price was where it should be for some one/reason.
