Are any experts here, who know why JPM and Citigroup built up such high positions in the commodity and precious metals market? http://www.zerohedge.com/news/2015-07-04/why-did-citigroups-precious-metals-derivative-exposure-just-soar-1260 I wonder about it since days. Is it good or bad? Are they long or short? What would have happened, if they didn't do this in Q1? My thought is, that commodities must extremely rise or extremely fall the rest of the year.
