Goldman Sachs Commodity Index. Pullback a full 750 points How far down will it go? Technical analysis tells us that it will have to "fill the gap" down at 640 before it can go up. I wouldn't bet the farm on this, but most traders trade technically and these things have a self fulfilling prophesy about them, always subject to reality changing things. BTW there is a second gap that "has" to be filled down at 600. Farm product price collapse is in full bloom. HOWEVER, much of the high price in commodities is due to that fucking ethanol, a product loved only by Congress, agribusiness, and environazis.
