For 50 years, equity markets exuberantly rose relative to Federal Reserve Assets. As post-WWII 'monopoly' production and credit expansion started to ebb (and bubbles were blown) so equity markets began to oscillate at 15 to 20 times their relative value from 1950. However, as the chart below shows [5], the entire 60 years of history preceding the 2008/9 collapse has been erased as a regime with the very clear picture that the Federal Reserve and the so-called 'US Equity Market' now tied at the hip. No matter how cognitively dissonant one remains that correlation is not causation; and no matter how many BTFATH newsletters one has to sell; after 60 years of moving from the lower-left-to-the-upper-right, something 'changed' when the Fed started printing money.
