NEW YORK (CNNMoney.com) - Stocks were mixed Wednesday morning, with only the Nasdaq composite managing to add to the prior session's broad-based rally.

The Nasdaq composite (up 4.64 to 2,300.54, Charts) added 0.1 percent in the early going. The Standard & Poor's 500 (up 0.37 to 1,297.85, Charts) index and the Dow Jones industrial average (up 75.32 to 11,151.34, Charts) both hovered near unchanged after finishing the previous session just short of five-year highs.

Stocks surged Tuesday, as falling bond yields helped relieve worries about rising interest rates.

But yields snapped back Wednesday.

Treasury prices slipped, raising the yield on the benchmark 10-year note to 4.72 percent from 4.69 percent late Tuesday. Treasury prices and yields move in opposite directions.

Part of the move in the bond market was just a reaction to the previous session's advance. However, bond investors were also likely reacting to the morning's stronger than expected NY Empire State Index.

The regional manufacturing index rose to 31.2 in March from the prior reading of 21.0. Economists surveyed by Briefing.com thought it would fall to 19.0.

Investors also took in a report showing a decline in import prices in February and a modest rise in export prices. Later in the day, the Fed's "beige book" survey of the economy will be released.

Among stock movers, Dow component DuPont (unchanged at $41.92, Research) rose 3.3 percent after boosting its first-quarter and full-year earnings per share forecast. The chemicals maker also said it was restructuring one of its units and would cut 1,500 jobs as a result.

SanDisk (up $1.95 to $55.37, Research), a flash memory chip maker, rose 4 percent after being upgraded by Pacific Crest Securities.

U.S. light crude oil for April delivery fell 39 cents to $62.71 a barrel in electronic trading, after adding more than 5 percent over the previous two sessions.
