This includes prices for 20 individual cities and and two composite indices (for 10 cities and 20 cities).
Note: Case-Shiller reports NSA, I use the SA data. The composite indexes were up about 0.2% in August (from July) Not Seasonally Adjusted (NSA), but declined Seasonally Adjusted (SA).
Data through August 2011, released today by S&P Indices for its S&P/Case-Shiller Home Price Indices … showed increases of +0.2% for the 10- and 20-City Composites in August versus July. Ten of the 20 cities covered by the indices also saw home prices increase over the month.d.
The first graph shows the nominal seasonally adjusted Composite 10 and Composite 20 indices (the Composite 20 was started in January 2000).
The Composite 10 index is off 32.2% from the peak, and down 0.2% in August (SA). The Composite 10 is 1.0% above the June 2009 post-bubble bottom (Seasonally adjusted).
The Composite 20 index is off 32.0% from the peak, and down 0.1% in August (SA). The Composite 20 is slightly above the March 2011 post-bubble bottom seasonally adjusted.
The Composite 10 SA is down 3.6% compared to August 2010.
The Composite 20 SA is down 3.9% compared to August 2010. This is slightly smaller year-over-year decline than in July.
The third graph shows the price declines from the peak for each city included in S&P/Case-Shiller indices.
Prices increased (SA) in 6 of the 20 Case-Shiller cities in August seasonally adjusted. Prices in Las Vegas are off 59.8% from the peak, and prices in Dallas only off 9.0% from the peak.
As S&P noted, prices increased in 10 of 20 cities not seasonally adjusted (NSA). However seasonally adjusted, prices only increased in 6 cities.
The small increase reported by S&P was seasonal.
