Sales talk pushed shares of Regal Entertainment (RGC) higher. The largest cinema chain in the country said it is considering strategic alternatives including selling itself. Merck (MRK) was by far the blue chips' worst performer. Investors didn't like that the company's earnings results were from cost-cutting, not strong sales.
