The Philly Fed ADS Business Conditions Index Update

Note: We've updated our periodic look at the Philly Fed ADS Index through yesterday's release, which includes last week's jobless claims.

The Philly Fed's Aruoba-Diebold-Scotti Business Conditions Index (hereafter the ADS index) is a fascinating but relatively little known real-time indicator of business conditions for the U.S. economy, not just the Third Federal Reserve District, which covers eastern Pennsylvania, southern New Jersey, and Delaware. Thus it is comparable to the better-known Chicago Fed's National Activity Index (more about the comparison below).

Named for the three economists who devised it, the index, as described on its home page, "is designed to track real business conditions at high frequency."

The index is based on six underlying data series:

  • Weekly initial jobless claims
  • Monthly payroll employment
  • Industrial production
  • Personal income less transfer payments
  • Manufacturing and trade sales
  • Quarterly real GDP

The accompanying commentary goes on to explain that "The average value of the ADS index is zero. Progressively bigger positive values indicate progressively better-than-average conditions, whereas progressively more negative values indicate progressively worse-than-average conditions."

The first chart shows the complete data series, which stretches back to 1960. We've highlighted recessions and the current level of this daily index through its latest data point.

Now let's take a closer look at the 21st century daily index. We've added a pair of dashed parallel lines highlighting a high-low channel since 2010. Our purpose was to give a better sense of direction for the economy. The top dashed line marks the post-recession peaks. The bottom line is parallel to it and positioned at the early 2013 low. The latest data point is fractionally below the upward trend. It will be interesting to watch this indicator over the next few weeks to see if it breaks out of the six-year channel.
