Federal Reserve Chairman Ben S. Bernanke’s indication that he will use “quantitative easing” to prevent deflation points to a stock market rally that may last for the next two years, Napier said. With quantitative easing, a tool pioneered by the Bank of Japan, central banks can stimulate inflation by printing money and flooding the market with cash in order to encourage consumers to spend.

The government’s efforts will eventually fail as ballooning government debt devalues the dollar, causes investors to flee U.S. assets and takes the S&P 500 to its eventual bottom in 2014, Napier said.

“Bear markets always end for exactly the same reason, and that is the market begins to price in deflation,” he said. “The results are always horrific.”
