S&P/Case-Shiller (August) and DataQuick (September)

Last week's August 2010 S&P/Case-Shiller appears to represent a peak and beginning of a decline in both Los Angeles and the 10-city Composite, now down 35.7% from its September 2006 peak, at December 2003 levels. The national (orange line, their original 10-city Composite) index is down 28.3% from its peak in June 2006. The Low, Middle, and High tiers are also graphed. The left column on the chart is peak to bottom; the right is peak to current month.

The DataQuick numbers for September also appear to show a downtrend for the four counties. Los Angeles County's median was at $340K, down 38.2% from its peak in August 2007. That left Los Angeles County at November 2003, Orange County prices at October 2003, Ventura County at April 2003, and San Diego County at July 2002.


Finally, here is the updated Los Angeles Case-Shiller index scaled with the Los Angeles DataQuick median price history (normalized Case-Shiller's January 2000 = 100). The Case-Shiller data is a month older and a three-month average.
