The Truth part is self-explanatory and when it comes to fear, it's the fear of passing up a good thing. It's just like two sides of the identical coin, acting synergistically to construct it's own momentum.
And there's that $15 trillion of central bank QE international liquidity sloshing about, which assists too lol
