The Press Release in a PDF file

This month’s release incorporates annual benchmark revisions to the composite indexes as well as a revision to the composition of the coincident index.*
  • The annual benchmark revisions bring the leading and coincident indexes up to date with all revisions in the underlying component data.
  • Gross domestic product was removed from the composition of coincident index.

    *See Historical Leading and Coincident Indexes graphs for a comparison between former and newly revised indexes.

The leading index decreased 0.2 percent in December, and the coincident index increased 0.1 percent. Taken together, the composite indexes indicate that economic activity in Germany in the first half of 2001 will not be as vigorous as the first half of last year.

  • Since reaching its highest value in February 2000, the leading index has declined steadily, pointing to slower economic activity in the coming months.
  • As indicated by the leading index, the strong upward trend in the coincident index seen in the first half of the year 2000 has leveled off going into 2001.

LEADING INDICATORS.  Three of the nine components of the leading index decreased in December. The negative contributors to the leading index —in order from the largest negative contributor to smallest— are stock price index, inventory changes, and yield spread. Four components of the index increased in December. These positive contributors —in order from the largest to smallest— are inverted growth rate of CPI for services, consumer confidence index, new orders in investment goods, and new residential construction orders. Gross enterprise and property income and number of applications for unemployment remained unchanged in December. 

With the decrease of 0.2 percent in December, the leading index now stands at 105.4 (1990=100). Based on revised data, this index decreased 0.3 percent in November and 0.1 percent in October. During the six-month span through December, the leading index declined 0.7 percent, and only four of the nine components increased (diffusion index, six-month span equals 44.4 percent).

COINCIDENT INDICATORS. Two of the four components of the coincident index increased in December. The increases —in order from the larger positive contributor to the smaller— are inverted unemployment rate and manufacturing sales. Retail trade volume held steady and industrial production declined in December. 

With the increase of 0.1 percent in December, the coincident index stands at 101.6 (1990=100).
This index decreased 0.2 percent in November, and increased 0.1 percent in October. During the six-month period through December, the coincident index increased 0.3 percent, with two of four series making positive contributions (diffusion index, six-month span equals 50 percent).

DATA AVAILABILITY.  The data series used to compute the two composite indexes reported in the tables in this release are those available "as of" 10 A.M. CET (Germany) on
January 26, 2001. At the time of the release, recent data for several of the series are based on estimates. In the leading index, new orders for investment goods industries, applications for unemployment compensation, yield spread, consumer confidence index, change in inventories, new residential construction orders and gross enterprises and properties income are based on estimates. In the coincident index, recent data for gross domestic product, industrial production, manufacturing sales and retail trade are also based on estimates.

THE CYCLICAL INDICATOR APPROACH. The composite indexes are the key elements in an analytic system designed to signal peaks and troughs in the business cycle. The leading and coincident indexes are essentially composite averages of between four and eight individual leading or coincident indicators. (See below for details.) They are constructed to summarize and reveal common turning point patterns in economic data in a clearer and more convincing manner than any individual component—primarily because they smooth out some of the volatility of individual components.

Historically, the cyclical turning points in the leading index have occurred before those in aggregate economic activity, while the cyclical turning points in the coincident index have occurred at about the same time as those in aggregate economic activity.

A change in direction in a composite index does not signal a cyclical turning point unless the movement is of significant size, duration, and scope. Historical analysis with U.S. data shows recession warnings are best determined by looking for negative growth of at least 1 percent, coupled with declines in at least half of the components over a six-month span. Further explanations of the cyclical indicator approach and the composite index methodology appear in The Conference Board’s Business Cycle Indicators page:     Methodology and Revisions.

As of January 2001, all components of the leading and coincident indexes
have incorporated annual benchmark revisions.

The component factors are inversely related to the standard deviation of the month-to-month changes in each component. They are used to equalize the volatility of the contribution from each component and are "normalized" to sum to 1. These factors are revised effective with this (January 30, 2001) release, and all historical values for the two composite indexes were revised at that time to reflect the changes. (Under normal circumstances, updates to the leading and coincident indexes only incorporate revisions to data over the past six months.)

The factors above were calculated using 1973-1999 as the sample period for measuring volatility for the leading index, and 1960-1999 as the sample period for the coincident index. There are additional sample periods as the result of different starting dates for the component data. When one or more components is missing, the other factors are adjusted proportionately to ensure that the total continues to sum to 1. For additional information on the standardization factors and the index methodology visit the following web page: Methodology and Revisions.

To address the problem of lags in available data, those leading and coincident indicators that are not available at the time of publication are estimated using statistical imputation. An autoregressive model is used to estimate each component. The resulting indexes are constructed using real and estimated data, and will be revised as the data unavailable at the time of publication become available. Such revisions are part of the monthly data revisions, now a regular part of the U.S. Business Cycle Indicators program. The main advantage of this procedure is to utilize in the leading index the data, such as stock prices, that are available sooner than other data on "real" aspects of the economy, such as and new orders and changes in inventory. Empirical research by The Conference Board suggests there are real gains in adopting this procedure to make all the indicator series as up-to-date as possible.
