The Economic Cycle Research Institute (ECRI) - a New York-based independent forecasting group, released their latest readings for their proprietary Weekly Leading Index (WLI) on Friday.
For the week ending December 31, 2010
- WLI is 128.9 down a tick from the prior week's reading of 129.0. The last time WLI was higher was the reading for the week of May 7, 2010 when it stood at 131.9.
- The lowest reading for WLI this year was 120.4 for the week ending July 16.
- Since apparently bottoming at -10.3 for the week of August 27, WLI growth moved higher or was flat for the 19th consecutive week to plus 3.3% from plus 2.3% a week ago.
- The last time WLI growth was higher was the reading for the week ending May 21, 2010 when it stood at positive 4.9%.
Since ECRI releases their WLI numbers for the prior week and the stock market is known in real time, you can sometimes get a clue for next week's WLI from the weekly change in the stock market. Notably, in the lead-up to the last two recessions, the WLI turned down months before the stock market did.
- The WLI for the week ending 1/7/11 will be released on 1/14/11
- Occasionally the WLI level and growth rate can move in different directions, because the latter is derived from a four-week moving average.
- ECRI uses the WLI level and WLI growth rate to HELP predict turns in the business cycle and growth rate cycle respectively. Those target cycles are not the same as GDP level or growth, but rather a set of coincident indicators (including production, employment income and sales) that make up the coincident index. Based on two additional decades of data not available to the general public, there are a couple of occasions (in 1951 and 1966) when WLI growth fell well below negative ten, but no recessions resulted (although there were clear growth slowdowns).
