Here are the headlines from the BLS report on Finished Goods:

About three-fourths of the November advance in the finished goods index can be traced to higher prices for energy goods, which jumped 6.9 percent. The indexes for finished goods less foods and energy and for finished consumer foods also contributed to the finished goods increase, both rising 0.5 percent.
Finished energy: The index for finished energy goods climbed 6.9 percent in November after advancing 1.6 percent a month earlier. About sixty percent of the broad-based November rise can be attributed to a 14.2-percent surge in gasoline prices. Increases in the indexes for liquefied petroleum gas and home heating oil also were major factors in the finished energy goods advance.
Finished core: The index for finished goods less foods and energy moved up 0.5 percent in November, its largest increase since a 0.5-percent gain in October 2008. Leading the November advance, the index for light motor trucks jumped 4.2 percent. Higher cigarette prices also contributed to the rise in the finished core index.
Finished foods: The index for finished consumer foods advanced 0.5 percent in November, its second consecutive monthly increase. Over sixty percent of the November rise can be traced to higher prices for fresh and dry vegetables, which climbed 8.7 percent.
