Over the past decade, the U.S. economy, as measured by nominal gross domestic product (GDP), has increased about 50 percent. This plots a GDP launch angle that is underwhelming when compared to the S&P 500. Corporate earnings have fallen far short of share prices. Hence, the bull market in stocks is not a function of a booming economy. Rather, it’s a function of Fed madness. And its existence becomes ever more perilous with each passing day.
