I sold most of my uranium stocks about 2 weeks ago when they started breaking down technically, but I kept a few that I thought had good fundamental potential. I had violated my own prime directive - DON'T TRY TO PICK STOCKS, YOU ARE NOT GOOD AT IT, lol!
The birds of a feather idea works better (at least for me) - when a sector cracks, sell everything in it. I'll wait for the inevitable bounce to sell the rest of my uranium stocks. Then I will avoid the sector for a long, long time. I think other sectors will do a lot better for the next few years.
