RE:You can recover and rebuild I agree with true377's excellent post.
It's just mean spirited to denigrate people when they're down. Stay in the market long enough and you'll likely find yourself taking a stake in a losing venture. My experience has been that anything can and does happen. I remember a director of Nortel quoted in Bloomberg as saying that bankruptcy was "not under consideration" the day before Nortel filed for it. Perhaps he was implying that the company had already decided to declare. I didn't interpret his words that way. I suffered a loss.
To those who have said that only the naive were caught here. Note that 249,300 shares were shorted sometime between August 31st and September 15th. I suspect almost all, if not all, were sold short on October 13th. Those folks were betting against the sale ever happening. One couldn't call them naive, but they're stuck every bit as much as the folks who bought and held. They need to replace the shares they borrowed and sold short, when WHY trades again. Should WHY not trade again, they must buy shares off market. Either way, they could end up paying a high price.
So if you've been caught at the end of the day, whether long or short, you have my sympathy and best wishes as you "recover and rebuild". I've been there.
