What are the 91-Day, 183-Day and 365-Day Growth Indexes shown in the Members Area?
The trailing 91-Day, 183-Day and 365-Day Growth Indexes (or sometimes shown as Growth %) are simply 91, 183 and 365 day (respectively) moving averages for the year-over-year net growth/contraction of the ‘Weighted Composite Index’. This are essentially the ‘areas under the curve’ that are ultimately used to calculate the corresponding ‘trailing percentiles’ through the statistical comparison of these values with one, two and four quarter GDP growth histories respectively in the U.S. Department of Commerce’s Bureau of Economic Analysis GDP Growth Tables. These ‘Growth Indexes’ are the year-over-year actual growth from which the ‘Trailing Percentiles’ are drawn.
