Earlier today I posted some analysis of the gap between existing and new home sales: Distressing Gap: Ratio of Existing to New Home Sales (see the post for several graphs - including the ratio between new and existing home sales)

Professor Brian Peterson has more (including some thoughts prices): House Prices and New versus Existing Homes Sales

To get a feel for how the two series [New and existing home sales] move together, figure 2 plots the percentage deviation for each series from its mean from 1975-2008. We see clearly that from 1975 to 2006 (the solid lines) that new home sales and existing homes sales move around together, with a correlation of 0.944 over the the time period up to 2006. However, as shown by the dashed lines, a gap has developed post 2006, resulting in the correlation for the sample from 1975-2008 falling to 0.876. There seems to be some type of a shock that is driving existing homes sale up relative to new homes sales.

I find it strange that most analysts are looking at existing home sales for stability in the housing market. I think the new home market is the place to look.
