Major US stock indexes nudged a bit further into record territory on Wall Street, but small-company stocks lagged behind, the AP reports. Gains for health care and retail companies were partly offset by declines in major technology stocks Wednesday. Amazon rose 1%, and drugmaker Mylan soared 16% after federal regulators approved its generic version of Teva's multiple sclerosis drug Copaxone. Facebook fell 1%. The Standard & Poor's 500 edged up 3 points, or 0.1%, to 2,537. The Dow Jones industrial average gained 19 points, or 0.1%, to 22,661, and the Nasdaq edged up 2 points, less than 0.1%, to 6,534. The Russell 2000 index of smaller companies fell 4 points, or 0.3%, to 1,507. More stocks fell than rose on the New York Stock Exchange.
