Pickings were slim in the new-high list Tuesday as the S&P 500 extended its losing streak to three sessions. Salix Pharmaceuticals (SLXP) jumped 9.34 to 169.17 after speculation heated up that the drugmaker is close to being bought by Allergan (AGN). Allergan is trying to thwart a hostile takeover by Valeant Pharmaceuticals (VRX).
