Home Prices Drop a Record 6.1%

This sector decline keeps snowballing and threatens to engulf us all:

Home prices in 20 major U.S. cities were down 6.1% on average in the past year as of October, according to the Case-Shiller price index released Wednesday by Standard & Poor's.

Since October 2006, prices in 10 cities fell 6.7% -- a record drop. The prior largest decline was 6.3% in April 1991.

"No matter how you look at these data, it is obvious that the current state of the single-family housing market remains grim," said Robert Shiller, chief economist at MacroMarkets LLC and co-developer of the index.

Eleven of the 20 metro areas posted a record low annual growth rate. Also, all 20 metro areas declined from the prior month as San Diego posted the largest decline -- 2.6%.
