Bullish Bets Jump Most Since July as Gold Rebounds: Commodities

Investors increased wagers on a commodity rally by the most in eight months as signs of a U.S. economic recovery bolstered the outlook for demand and drove rallies in crude oil, cotton, copper and gold.
Hedge funds and other large speculators raised net-long positions across 18 U.S. futures and options in the week ended March 12 by 30 percent to 528,680 contracts, the biggest gain since July and up from a four-year low the previous week, U.S. Commodity Futures Trading Commission data show.
