Stocks trimmed gains shortly after the open on Monday as declines in technology shares offset a bounce in financials on reports that Washington could end up with a big stake in Citigroup common stock.

Citigroup Inc is in talks to give the U.S. government a larger stake, a person familiar with the matter said, while The Wall Street Journal said Washington may end up holding as much as 40 percent of its common stock.

The Dow Jones industrial average <.DJI> added 45.96 points, or 0.62 percent, to 7,411.63. The Standard & Poor's 500 Index <.SPX> gained 4.14 points, or 0.54 percent, to 774.19. The Nasdaq Composite Index <.IXIC> was down 2.43 points, or 0.17 percent, at 1,438.80.
