We explained last week [3] why the initial exuberance from QEternity was likely to fade since it basically removed all suspense from futures FOMC announcements - i.e. that bad news would once again become bad news as opposed to bad news stoking the hopes or more-er QE. Well this morning's bad news - to wit: China PMI, Europe PMI, and US initial claims - has indeed had a detrimental impact on S&P futures as they approach fresh post-FOMC lows.
S&P 500 futures face quite a cliff here...
