Nouriel Roubini prefers to be referred to as "Dr. Realist" instead of "Dr. Doom."
He gained the nickname "Doom" in 2006 and 2007 when he correctly predicted the global economic collapse.
During that time Roubini was advising that investors be out of or underweight global equities.
Today he sees a global economic recovery and is certainly not a permabear.
He believes that gradually interest rates are going to rise so investors should be underweight bonds and slightly overweight global equities in order to take advantage of the global economic recovery.
