Who can argue with the S&P 500's 155% gain since March 2009?
The current run has already surpassed the impressive 101% gain from October 2002 to October 2007. In fact, the five-year S&P chart is so awe-inspiring, it's now on the verge of rivaling Michelangelo's David in the canon of masterpieces.
The S&P 500 has made one all-time high after another this year and gained nine out of the past 10 years.

Remember David Rosenberg? He's a well-known economist who was formerly an outspoken bearish deflationist.
