Former Goldman Sachs analyst Charles Nenner warns a major financial collapse is coming in 2018-2020

Charles Nenner, who has claimed to have never been wrong on a market call, appeared on CNBC and warned that deflation and a stock market crash both coming. Nenner, who developed the “Nenner cycle,” which he says can time the ups and downs of any market, said on CNBC that “for the next many years, you will not see the S&P more than 5% higher than [current levels.]” But he warns this period of low returns will be followed years of large losses.
