Interesting trio of charts from Russell showing the Business Cycle Index (BCI).
The goal of the BCI is to forecast the strength of economic expansion or recession in the coming months, along with forecasts for other prominent economic measures. How well it does that is a subject of debate.
Inputs to the model include non-farm payroll, core inflation (without food and energy), the slope of the yield curve, and the yield spreads between Aaa and Baa corporate bonds and between commercial paper and Treasury bills. A different choice of financial and macroeconomic data would affect the resulting business cycle index and forecasts.
