The Enhanced Aggregate Spread (EAS) comes from Robert Dieli, and most of the following description of this indicator, and why it works, is from personal communications.
The EAS can signal, as much as nine months ahead, when either a cycle peak (recession start) or a cycle trough (recession end) is likely to take place.
Armed with that information, decision makers can make appropriate plans. As of this writing (May 2016), it signals that it is highly unlikely for a recession to begin before the end of 2016.
