The Low Correlation Between the Stock Market And Economic Growth

Analyst John Mauldin cites Crestmont Research’s Ed Easterling who argues “stock market is not correlated with economic growth”.

They say “secular bear markets even have higher nominal GDP growth than secular bulls”, with the chart below as proof…

And also say “34% of the years since 1950 with economic growth have experienced declining earnings per share (EPS) growth!” Again a series of chart below as proof…

I am puzzled.

If “low correlation” means economic growth has not functioned as a good indicator of the direction of the stockmarket price trends, then why the heck, do these experts keep talking about various aspects of “economic growth” at all? This is obviously a cognitive dissonance.

One factor for the insistence of the “economic growth” conversation could be that they don’t agree with the referenced opinion.

A second factor could be entertainment value. Experts write to entertain more than to disseminate positive knowledge.

A third factor could be to use of such contrarian evidence as cover to their earlier misdiagnosis of the markets and the attendant mistakes in prediction.

Finally this could all be about social signalling.

Yet this just goes to show how more and more ‘experts’ appear to be getting lost or confused about what’s been going on. In other words, traditional methodologies and metrics are becoming more dysfunctional.

And all this provides more credence to what I’ve been saying all along.
