Is the Federal Reserve’s quantitative easing stimulus program responsible for stock market gains?

There are two schools of thought on this: Yes, and No.

The Yes camp maintains that the easy money being pumped into the economy (via quantitative easing) by the Federal Reserve flowed not into the real economy but financial markets, inflating the price of stocks, bonds, and other financial assets.

The No camp says that a recovering US economy and steady earnings growth has powered the market higher. 

Ethan Harris, a global economist at Bank of America Merrill Lynch, wrote in a note to clients over the weekend: “Every time the end of a QE program looms, pundits warn of a big shock to markets and the economy. In the business press, the story of exactly how this happens keeps shifting to fit the facts.”

The main target of Harris’ critique is the above chart, which has been a favorite among the “QE-truthers,” or folks who believe the Fed’s policies are directly responsible for the rise in the stock market. 

But the big problem Harris has with this chart is, well, basic statistics. 

Implicitly, this chart assumes that the markets are not forward looking and it is the implementation of Q that drives the stock market: when the Fed buys, the market booms and when it stops, the market swoons,” Harris wrote.

“As our readers know, we think this relationship is a classic case of spurious correlation: anything that trended higher over the last 5 years has a 90%-plus correlation with the Fed’s balance sheet.”

Harris also walks through multiple narratives that have shifted over the past few years, pointing out, among other theories, the idea that the Fed ending its QE program could have caused a selloff in bonds in 2013 but a rally in 2014. 

“Boy is ending QE powerful,” Harris wrote. 

In our latest Most Important Charts feature, Greenlight Capital’s David Einhorn highlighted the trouble with correlations, pointing out that the “any two lines” school of charting and financial argument can be not just highly — but ridiculously — flawed. 

Here are two facts: the size of the Fed’s balance sheet has risen in the past five years; the stock market has risen in value over the past five years.

That one of these caused the other is less clear.
