Early gains Monday were all but erased in the afternoon as buyers moved out of the way of two upcoming inflation reports this week.

The

Dow Jones Industrial Average

was ahead by more than 100 points for a time, but closed higher by only 9.84 points, or 0.09%, to 11,097.87. The

S&P 500

added 1.47 points, or 0.12%, to 1268.21, and the

disclosure late Friday that it would continue oil production from the western side of Alaska's Prudhoe Bay field. Current production is 150,000 barrels a day, including natural gas liquids, and should soon increase to 200,000 barrels a day.

Oil prices rose early last week after BP said it would take 400,000 barrels a day off line in order to repair a corroded pipe. Gasoline and natural gas futures also were declining. BP, which slid 3.6% last week, gave back another 2 cents, or 0.1%, to $69.30.

The 10-year Treasury lost 7/32 in price to yield 5%, while the dollar rose against the yen and weakened against the euro.

Later this week, the government will release both the producer price index and the consumer price index. Investors will use the numbers to help them gauge the odds of another

rate hike at the central bank's next meeting. Last week, the Fed left its fed funds target rate unchanged at 5.25% after 17 straight quarter-point hikes.

"With the macroeconomic reports due out later this week, people are uncertain of what these will show," said Jay Suskind, head of institutional equity trading with Ryan Beck.
