Do investors really understand the economy or the business cycle? The recent surge in the market indices questions whether the markets believe there is a relationship.

As I have said many times in the past – there do not need to be short term correlations between the economy and the markets. There are millions of reasons why the markets go one way, and the economy goes the other way. Looking at corporate profits indexed since 1990 shows corporate profits have advanced at nearly double the rate of Gross Domestic Income improvement. Clearly profits had been growing much faster than the economy.

But since the Great Recession (aka New Normal), there is a much tighter correlation between corporate profits and economic growth.

The new normal would suggest the market pay closer attention to Gross Domestic Income as a guide to market valuation. As the market is forward looking, knowing the economic situation months from now is necessary. It seems most forecasters are projecting economic growth around 2.8% over the coming 12 months – and this would suggest likewise that the market rise over the next 12 months should be in this range also.

This past week we issued our economic forecast which remains at one of the lowest levels since the end of the Great Recession. Our economic forecast is designed as a measure of Main Street – not as a forecast for GDP. However there are correlations as can be seen on the below graphic.

GDP Year-over-Year Growth (red line) vs Econintersect Economic Index (blue line)

Econintersect believes looking at year-over-year growth is a better way at looking at GDP – and our economic forecasts are based on year-over-year growth. In addition, our forecasts are issued four months in advance of GDP publication.

From all the evidence we are seeing – economic growth will be moderate at best over the next six months. Market valuation (based on New Normal historical correlations) should follow this moderate growth.
