2 years ago rare earths were a bit of a "rage"  i remember cin.v waiting for purity results that dragged on and on.. then about 2 months later the stock was halted.. out came the news.. halt ended and the stock opened  about 40 cents LESS than when it was halted. as far as i know everyone took a bath.  15 cents to 70 cents to 1 cent.. probably be gone before summer.

So it is always good to take some profit because sooner or later they will get some of it back from your pocket.
