Stocks were expected to open weaker Friday after a mixed session Thursday.

On Thursday, the blue-chip Dow Jones Industrial average closed lower by 51.22 points, or 0.60%, to 8,537.92. The broader Standard and Poor's 500-stock index lost 3.42 points, or 0.38%, to 901.54.

Investors await still more economic news on Friday. Keenly anticipated on the heels of Thursday's bright retail sales numbers is the University of Michigan consumer sentiment index. The producer price index, which measurs prices paid to U.S. factories, farmers, and other producers, unexpectedly plunged 0.4% in November -- the largest decline in six months -- as costs declined for gasoline, computers and cars, a government report showed.

The oil cartel OPEC decided to raise immediate oil production by 1.3 million barrels a day, but also said producers would gradually move to lower output as peak winter demand subsides.

Treasury Market

Treasuries were mixed in price Friday morning after a sudden wave of selling, which MMS International says has anecdotally been tied to the duration gap for Fannie Mae's debt portfolio going positive, which could attract investors out of Treasuries. This represents a sharp reversal from the deeply negative duration gap only a couple months back. The drop in PPI is also thought to be mostly from the auto sector as well, which takes some of the starch out.
