In general, increasing coincident index shows that the economy is in an expansion phase, and decreasing coincident index reflects that the economy is in a contraction phase. The index is calculated using month-over-month percentage changes in 11 leading indicators, 11 coincident indicators, and 6 lagging indicators.
