Americans have been wondering if the housing market is in a double bubble for a little while, since Professor Robert Shiller, co-creator of the Case-Shiller house price indices, raised the danger.
The real action has been in housebuilders, though. Their valuations, based on price to estimated book value, peaked in May above where they stood at the height of the property bubble in 2005/6. Prices look very much like the rebound bubble in the Nasdaq, in the Dow Jones Industrials in the late 1930s and in the Nikkei 225 (although it wasn’t quite so big).
