On March 9, 2018, the bull market in U.S. stocks will celebrate its ninth anniversary. And, what we find most amazing is how few people truly understand it. To this day, in spite of massive increases in corporate earnings, many still think the market is one big "sugar high" – a bubble built on a sea of Quantitative Easing and government spending.

While passing mention is given to earnings (because they are impossible to ignore), conventional wisdom has clung to the mistaken story that QE, TARP, and government spending saved the economy from the abyss back in 2008-09.

A review of the facts shows the narrative that "Wall Street" – meaning capitalism and free markets – failed and government came to the rescue is simply not true.

Wall Street was not the driving force behind subprime mortgages. In his fabulous book, Hidden in Plain Sight, Peter Wallison showed that by 2008 Fannie Mae, Freddie Mac and other government programs had sponsored 76% of all subprime debt – not "Wall Street." Everyone was playing with rattlesnakes and government was telling them it was OK to do so. But, when the snakes started biting, government blamed the private sector, capitalism and free markets.

At the same time, Wall Street did not cause the market and economy to collapse; it was overly strict mark-to-market accounting. Yes, leverage in the financial system was high, but mark-to-market accounting forced banks to write down many performing assets to illiquid market prices that had zero relationship to true value. Mark-to-market destroyed capital.

QE started in September 2008, TARP in October 2008, but the market didn't bottom until March 9, 2009, five months later. On that day in March, former U.S. Representative Barney Frank, of all people, promised to hold a hearing with the accounting board and SEC to force a change to the ill-advised accounting rule. The rule was changed and the stock market reversed course, with a return to economic growth not far behind.

Yes, the Fed did QE and, yes, the stock market went up while bond yields fell, but correlation is not causation. Stock markets fell after QE started, and rose after QE ended. Bond yields often rose during QE, fell when the Fed wasn't buying, and have increased since the Fed tapered and ended QE.
