A well written story about the "darkness" of the commodity futures market, oil trading in particular. The speculative nature of the market overwhelms. in my opinion more than ever, the so called "natural regulator" role of it. "Demand and supply", could have been lots of years back now is more and more controlled "demand and supply". And guess who is using this? The hedge funds that make millions to the million+ club member not your lame 401 K fund that basically funnel your money into their profits. All kind of "financial vehicles" popped up on the market (gee, there has to be a reason why financial stocks are not recommended now) and obviously the "innovation" continue. Everybody expects government regulations to do the job forgetting/or not knowing the new nature of commodities trading - "dark" and packed in layers of info that will take for ever to figure out. Only few (these billions dollars fund managers) can make these new world work in their favor although some of them crashes also. It is more an more an inner game where a regular investor is most of the time a looser.
