NEW YORK (AP) — U.S. stocks couldn’t hang on to an early gain and finished mostly lower Monday as technology companies slipped. Bond prices continue to fall and the yield on the 10-year Treasury note drew closer to 3 percent, a milestone it hasn’t reached since January 2014. Investors once again focused on corporate deals Monday as utility company Vectren agreed to be bought by CenterPoint Energy for $6 billion, while the CEO of Sears called for the company to sell more assets and health care products company Henry Schein said it will split off its animal health unit.
