1、For commodity markets, the third iteration of U.S. central bank stimulus may play like many movie sequels - a familiar plot, a predictable rise, yet less potent than the original. But the Federal Reserve has introduced a new twist on its latest round of quantitative easing (QE), one that is giving s

And the percentage of gains after each stimulus has been diminishing.The critical question facing investors now is how long this stimulus round will last,

9、ounds in 2008 and 2010, commodity markets showed sizeable gains after months, not weeks.Brent, for instance, saw a 12 percent price decline in the first three months after QE1, launched in the aftermath of the Lehman Brothers collapse in 2008 which triggered the global financial meltdown. Six months
