As I wrote in anpother CDU post today, selling out of a stock on a downward trend (or selling at any time) can make sense. CDU wasd $4.50 a short time ago- now it's $3.59. That's 20% down. Had I sold @ $4.50, how would it have made profit for the buyer? It would be the buyer down 20% and not me, the holder, down 20%. The buyer would need to make up 20% to be even.
