Oil prices rose $4 to $39 per barrel on Friday (midday) on global growth concerns, according to Standard & Poor's U.S. Financial Notes. S&P expects oil prices to recover part of their losses, but geopolitical risk makes the forecast highly uncertain. Natural gas futures fell 9.1% to $4.1 per mbtu through Thursday, despite cold weather. Meanwhile, gold futures climbed $28 to $977 per ounce, revealing investors' risk aversion. Agriculture prices fell 4.3% and are down 44.8% for the year. Livestock stocks fell 3.9% this week and are down 29.7% for the year. Overall, U.S. equity indices were down this week, on investor worries over the health of banks and skepticism about the stimulus package, according to the report. The Dow hit a new six-year low, falling below the Nov. 20 bottom. Through Friday (midday), the S&P 500, Dow, and NASDAQ dropped to 772, 7,406, and 1448, respectively.
