Presented with little comment aside to warn - beware the serial extrapolators...
Chicago PMI "soared" well above expectations to 57.9 in Auguest 2008, only to 'plummet' to 37.8 by October 2008...

As an additional gentle reminder, while the official data was blithely ignorant of the fact at the time, when Chicago PMI went from 46.6 in Feb '08 to 56.8 by Sept '08, we were already 9 months into the recession!
