On a fundamental basis stock prices are reflective of both economic and earnings growth. When growth is strong, stock prices should increase in value. And when economic activity decelerates or turns negative, stock prices should go down. Of course nothing is that simple -- especially today, when all markets are so highly manipulated by governments and central banks. Beginning in 2008 the markets followed the Fed on a magical journey down the rabbit hole into a wonderland where bad news is good news; and economic fundamentals and stock prices no longer move in tandem.

This delusion has been fomented by the specious notion that QE and ZIRP will eventually cause economies to catch up to record-high stock valuations.

Perhaps the best example of this fiction is the nation of China, where the ride on the command and control economy has left the communist country perched atop two massive asset bubbles. One in real estate, whose foundation is empty cities, and one in the Shanghai Index, whose value is based on companies that have, at best, questionable accounting practices. But why let a lot of manipulated facts get in the way of a really exciting asset-bubble story. For an exploit in pure froth, China doesn’t disappoint.
