May 2013 Coincident Indicator Review: Philly Fed USA Coincident Index Shows Continued Economic Growth
A comparison of US Coincident Index, Aruoba-Diebold-Scotti business conditions index, Conference Board's Coincident Index, ECRI's USCI (U.S. Coincident Index), and Chicago Fed National Activity Index (CFNAI) coincident indicators follows.
Economic indicators that coincide with economic movements are coincident indicators. Coincident indicators by definition do not provide a forward economic view. However, trends are valid until they are no longer valid, making the trend lines on the coincident indicators a forward forecasting tool.
Excerpt from Philly Fed Report for the United States Coincident Index
The Federal Reserve Bank of Philadelphia has released the coincident indexes for the 50 states for May 2013. In the past month, the indexes increased in 33 states, decreased in eight states, and remained stable in nine, for a one-month diffusion index of 50. Over the past three months, the indexes increased in 43 states, decreased in five, and remained stable in two, for a three-month diffusion index of 76. For comparison purposes, the Philadelphia Fed has also developed a similar coincident index for the entire United States. The Philadelphia Fed’s U.S. index rose 0.2 percent in May and 0.7 percent over the past three months.

The Philly Fed also produces this real time coincident indictor report based on six underlying indicators:
- Weekly initial jobless claims
- Monthly payroll employment
- Industrial production
- Personal income less transfer payments
- Manufacturing and trade sales
- Quarterly real GDP
However, the vertical lines on the chart above indicate the amount of indicators used to develop this forecast.
- For dates to the left of the left line, the ADS index is based on observed data for all six underlying indicators.
- For dates between the left and right lines, the ADS index is based on at least two monthly indicators (typically employment and industrial production) and initial jobless claims.
- For dates to the right of the right line, the ADS index is based on initial jobless claims and possibly one monthly indicator.
This means the accuracy of this index is reduced in real time. Per the Philly Fed:
The Aruoba-Diebold-Scotti business conditions index is designed to track real business conditions at high frequency. Its underlying (seasonally adjusted) economic indicators (weekly initial jobless claims; monthly payroll employment, industrial production, personal income less transfer payments, manufacturing and trade sales; and quarterly real GDP) blend high- and low-frequency information and stock and flow data. Both the ADS index and this web page are updated as data on the index's underlying components are released.
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 ADS index may be used to compare business conditions at different times. A value of -3.0, for example, would indicate business conditions significantly worse than at any time in either the 1990-91 or the 2001 recession, during which the ADS index never dropped below -2.0.
