U.S. stocks edged lower shortly after the open on Tuesday in the wake of the latest records for the Dow and S&P and the Nasdaq scaling the 5,000 mark for the first time in 15 years. The Nasdaq had notched its first close above the 5,000 milestone since March 10, 2000, buoyed by merger activity, for only the third close above that level in the history of the index. The Dow and S&P closed at their latest records as economic data pointed to a slowly improving economy. "The market is naturally settling in, taking a breather until the scales tip either way to commence the next move to continued to new heights or a consolidated pullback," said Andre Bakhos, managing director at Janlyn Capital LLC in Bernardsville, New Jersey. "It's a pause before the next set of impactful numbers come out, highlighted by the jobs report on Friday."

For the second year in a row, ferocious winter weather slowed U.S. vehicle sales in February, with several major automakers missing analysts' projections and dampening bullish expectations.

Citigroup edged up 0.3 percent to $53.67 after it agreed to sell its consumer finance unit OneMain Financial Holdings Inc to subprime lender Springleaf Holdings Inc for $4.25 billion in cash. Springleaf shares surged 31.8 percent to $50.14. Mylan Inc fell 2.3 percent to $56.55.
