George Soros wants to outdo Alan Greenspan and Ben Bernanke by adding his not so elequontly worded quotes.("irrational exuberance" "Unusually Uncertain economy") But then we can forgive him as English is not his first language.

"Gold is the ultimate bubble"
"No assets are safe in this environment of great undertainty"
"Once an asset class hits new highs almost certainly it is like to reverse and disappoint investors"
