Yet another story of a speculator trying to corner a market. http://online.wsj.com/article/SB100...34083436931412.html?mod=WSJ_hp_LEFTTopStories A few months ago, "cocoa-finger" cornered the London market in cocoa. Earlier this year, we saw Ebullio drop by 96% in 2 months after it tried, and failed, to corner the market in some industrial metals. The resulting market disruption is often severe. Why is the UK allowing this sort of ridiculous, market-disrupting activity to go on? It wouldn't be possible in the US (or at least not as blatantly) because of position limits and government regulation. It makes me hesitate to get into any commodities traded out of London.
