One of the seemingly infinite drawbacks of Europe's inability to contain its debt crisis: slow economic growth causing lower demand for raw materials.

Bloomberg reports that speculators curbed wagers on higher commodity prices for the first time in four weeks. As a result, over $1.4 trillion was erased from the value of global equities last week.

"Money managers cut combined net-long positions across 18 U.S. futures and options by 3.9 percent to 798,787 contracts in the week ended Nov. 1, Commodity Futures Trading Commission data show. The Standard & Poor's GSCI Index of 24 raw materials has tumbled 13 percent since reaching a 32-month high in April."

More commodity highlights from Bloomberg:

  • Bets on higher crude prices declined 3.6 percent and those on gasoline slid 2.4 percent, falling for the first time in five weeks.
  • Speculators are now the most bearish on soybean prices in almost 16 months, and they expanded wagers on a retreat in wheat by 24 percent.
  • Net-long positions in gold advanced 6.8 percent to the most in six weeks and in silver by 9.5 percent to a five-week high.

Not all is lost for commodities as several economies still plan to expand in 2012. Next year's U.S. growth is anticipated to grow by 2.05%, according to the median estimate of 80 economists surveyed by Bloomberg. This would be a nice increase from this year's 1.7% growth.

Furthermore, the world's biggest consumer, China, is expected to grow 8.6% in 2012. This is "12 times the pace of the euro region, the estimates show."

Investing ideas
Hedge funds are turning more cautious on the outlook for commodities, so we're wondering: which commodity companies are expected to be dragged down?

For ideas, we collected short-seller trends data for the 200 largest commodity companies trading on U.S. markets. Below we list eight names that have seen a significant increase in shares shorted over the last month (i.e., an increase in bets that their share prices will decline).

Short-sellers think these companies are in trouble, and hedge funds seem to think commodity prices are vulnerable to a correction. Do you agree with this excessive pessimism?
