Quote "Be fearful when others are greedy. Be greedy when others are fearful."
This is one of the techniques used by professional investors to increase the value of their portfolios. It basically means they are deliberately out-of-phase with the rest of the market sentiment. This acts as a vast wealth-pump, the smart money moves into a low-priced investment before anyone else knows about it. When the news mentions it, the dumb money moves in, and is often the case, the smart money has moved out taking the dumb money with them.
