Knowing when the U.S. Economy is heading for recession is paramount for successful investment decisions. Our weekly Business Cycle Index (BCI) would have provided early reliably warnings for the past seven recessions.

The BCI at 196.8 is up from last week’s downward revised 195.5, the BCI is now just below its previous peak  of 196.9 indicated by BCIp of 99.6 .  However, the 6-month smoothed annualized growth BCIg  at 11.4 is lower compared to last week’s  downward revised 11.7.   No recession is signaled.

The downward revision of BCI and BCIg follows the Census Bureau’s downward revision of past reported New Residential Sales.

Figure 1 plots BCIp, BCI, BCIg and the S&P500 together with the thresholds (red lines) that need to be crossed to be able to call a recession.

The BCI uses the below listed economic data, and combining the components for the index in “real time”, i.e. the data is only incorporated into the index at its publication date.

  1. 10-year treasury yield (daily)
  2. 3-month treasury bill yield (daily)
  3. S&P500 (daily)
  4. Continues Claims Seasonally Adjusted (weekly)
  5. All Employees: Total Private Industries (monthly)
  6. New houses for sale (monthly)
  7. New houses sold (monthly)

The 6-month smoothed annualized growth rate of series is a well-established method to extract an indicator from the series. We use this method to obtain BCIg, i.e. the calculated growth rate with 6.0 added to it, which generates, on past performance, an average 11 week leading recession signal when BCIg falls below zero. Further, the index BCI retreats from its cyclic peak prior to a recession in a well-defined manner allowing the extraction of the alternate indicator BCIp (and its variant BCIw) from which, on average, 20 week leading recession signal is generated when BCIp falls below 25.

Also, the historic values can be downloaded from iMarketSignals as an MS excel sheet.

Figure 2 plots the history of BCI, BCIg, and the LOG(S&P500) since July 1967, and Figure 3 plots the history of BCIp, i.e 46 years of history which include seven recessions, each which the BCIg and BCIp managed to indicate timely, the weeks lead to a recessions are indicated on the plots.
