Every month, and quarter, economists, analysts, the media, and investors pour over a variety of mainstream economic indicators from GDP, to employment, to inflation to determine what the markets are likely to do next.

While economic numbers like GDP, or the monthly non-farm payroll report, typically garner the headlines, the most useful statistic, in my opinion, is the Chicago Fed National Activity Index (CFNAI). It often goes ignored by investors and the press, but the CFNAI is a composite index made up of 85 sub-components, which gives a broad overview of overall economic activity in the U.S.

The markets have run up sharply over the last couple of months due to the Federal Reserve once again intervening into the markets. However, the hopes are that U.S. economic growth is going to accelerate going into 2020, which should translate into a resurgence of corporate earnings. However, if recent CFNAI readings are any indication, investors may want to alter their growth assumptions heading into next year.

While most economic data points are backward-looking statistics, like GDP, the CFNAI is a forward-looking metric that gives some indication of how the economy is likely to look in the coming months.

Importantly, understanding the message that the index is designed to deliver is critical. From the Chicago Fed website:

“The Chicago Fed National Activity Index (CFNAI) is a monthly index designed to gauge overall economic activity and related inflationary pressure. A zero value for the index indicates that the national economy is expanding at its historical trend rate of growth; negative values indicate below-average growth; and positive values indicate above-average growth.“

The overall index is broken down into four major sub-categories which cover:

  • Production & Income
  • Employment, Unemployment & Hours
  • Personal Consumption & Housing
  • Sales, Orders & Inventories
