July’s 12.8 percent plunge in new home sales is a function of the ridiculously large revision to June’s sales (from a preliminary SAAR of 646,000 units to a 12-year high of 728,000); had June’s estimate not been revised, July’s retreat would have been a relatively mundane -1.7 percent. The Census Bureau made sweeping revisions to construction spending (spanning back to January 2013 in the not-seasonally adjusted series), in the process adding $72.5 billion to total spending but subtracting $1.5 billion from the private residential component.
