On the home page of this site, under Stats & Charts, etc. are 5 new reports in the style I have been using for several years. If you are not familiar with these charts, the 4 that say Absorption Rates display the length of time it would take for all current inventory to sell based on the volume of sales over the previous 12 months. The solution to the puzzle is stated in number of months, in the right column of each chart.
Also the Monthly Sales chart shows at a glance how the ebb and flow of sales is affected by seasonal business, lower in the winter and climbing from summer through fall. We continue to see improving trends in all segments and are hopeful the worst is behind us.
