The Dow Jones industrial average (search) gained 3.62 points, or 0.03 percent, to close at 10,553.49. The Standard & Poor's 500 Index (search) added 2.07 points, or 0.17 percent, to end at 1,204.29.

"Are we in that perfect 'Goldilocks' kind of economy, or are the numbers here pointing to new problems?" said Jay Suskind, head trader at Ryan Beck & Co. "So in front of tomorrow's employment numbers, the market lays an egg and we wait."

The Labor Department report showed that unit labor costs increased at a 3.3 percent annual rate in the first quarter, far sharper than the 2 percent increase that was forecast.
