In the end of September, hedge funds had reduced their bets on higher commodity prices only days before raw materials rallied the most in 10 weeks -- they've since double-backed. Bloomberg reports hedge funds, in the week ended Dec. 27, have raised wagers on rising commodity prices the most in 16 months.

Net long positions increased by 18% to 536,907 contracts. The increase is the greatest since August 2010, according to data from the Commodity Futures Trading Commission.

James Paulsen, chief investment strategist at Wells Capital Management, tells Bloomberg the commodities have already formed a bottom because the U.S. has demonstrated sustained economic growth. "Data out of the U.S. flies in the face of recession. More and more people are saying: 'Maybe things are not that bad.'"

Still, the future of commodities and indeed most economic indicators are in limbo as long as Europe and the U.S. face the prospect of a recession. A downfall from either the EU or the U.S. would have a significantly negative impact on global markets.

Twelve of the 24 commodities on Standard & Poor's GSCI Total Return Index rose last week, reports Bloomberg. The gains were led by Wheat traded in Kansas City -- up 6.2%, followed by cotton at 5.2%. "Gold futures climbed 2.3 percent, heading for the biggest advance since Oct. 25."
