Bloomberg – Hedge funds and large speculators increased their bets on a commodity rally to the highest level since at least 2006 as copper and gold gained to records.
An index tracking speculative positions in 20 commodity futures in the U.S. advanced 8.4 percent from the week before to 1.54 million contracts as of Dec. 7, the highest level since at least February 2006, Commodity Futures Trading Commission data show. The gauge, compiled by Bloomberg, is derived by taking short positions, or bets on lower prices, from long positions.
