<i>"why there is sudden down?"</i>
Well, let's see...
#1: China stocks get a dose of reality as inflation affects China and the U.S. via commodities.
#2: German central banker reiterates ECB is focused on containing inflation above all else, i.e. no rate cuts (or perhaps subsequent hikes?) as commodities spiral straight upwards.
No ECB / BOE cut pending pressures Bernanke & ilk to either stand pat or retract the latest cut with their own hike before next series of rate cuts can begin.
I wonder how an end to cheap money = lower rates might be interpreted by world indexes? Hmmm... let me pull up the charts for this afternoon and see how everyone feels about this...
