— It isn't taking commodities long to shake off the post-holiday doldrums.
Commodity prices jumped across the board Tuesday after positive economic news from the United States and other countries helped ease concerns about Europe's financial troubles. The gains came after oil and metals contracts fell last month.
Investors are encouraged by reports that U.S. manufacturing expanded in December at the fastest pace in six months and construction spending rose 1.2 percent in November. And China says its manufacturing sector is improving.
Silver is up 5.9 percent to lead metals prices higher.
Oil rose 4.2 percent as concerns grew over the possibility that Iran may try to close a strategic waterway in the Persian Gulf.
Other energy and agriculture products also are posting gains.
