Divide between Wall St. and Main St. an extension of the last financial crisis: David Rosenberg

David Rosenberg, founder of Rosenberg Research, says there are a lot of things that drive equity, such as liquidity, valuations, and sentiment. Although earnings may have beaten expectations, the market's been driven by liquidity, Rosenberg says. He also addresses the divide between Wall Street and Main Street, and discusses his outlook on bitcoin, cyclical stocks, and the newly-nominated Janet Yellen to be Treasury secretary.
