I hope you sold early enough to make a difference to you financially. For most of us it is too late.
But until we know whether NWBO goes BK or succeeds it is not really over because you have to worry about selling being a big mistake.
Sometimes I think I can singlehandedly cure cancer by selling my shares and of course the next morning, Ms. Powers will reveal all the data etc. etc. and it is the type that will get approval.
I suppose you can go the litigation route (a real long shot) but leaving that aside, once you've sold, any chance of making a recovery is gone and with 90% or greater in losses I did not see the point in selling. But then again, I do not have such a large position, so there's that.
