The way I see this, there are 2 alternatives regarding this stock.
1. One can keep the stock and wait for some one to buy the shell. This way, one can ride the stock and wait to recover, totally or partly, the money invested. It may be a good alternative and would warrant buying more, although at a much lower price than it is now. An empty shell is worth a decent sum of money in itself on the market in addition to the product of whoever would use it. Furthermore, buy keeping the shares, one could guarantee some benefits in the event that any lawsuits might be successful although not very probable.
2. One can sell now at a loss and avoid the total loss of investment if the initial investment was modest; otherwise, it will a big loss.
