actually scriket, I don't think YOU should ever sell. As a matter of fact, I think YOU should continue buying all the way down. Just because that strategy has cost you thousands and thousands to this point, I am sure you still have some left to give.
If not, maybe you can get a part-time job or give blood, or something. I just don't think you should ever stop donating to the "friendlies". You would only lose your money on something else anyway, so you might as well do it in a manner that provides amusement to me.
