Yes, definitely was a learning experience. I don't know if shares are moved around from time to time to keep the ticker active enough to keep it from getting delisted, completely or if someone is throwing a few bucks at it on pure off chance and speculation.

However, there are plenty of other shells out there to speculate on. I don't know why anyone would pick this one.

There is only the dimmest of hope that somehow at the end of litigation COR is made whole and the ticker comes out clean for someone new to buy and do something with. But I wouldn't recommend anyone buy shares based on that.
