Morgan Chase & Co. /zigman2/quotes/205971034/composite JPM -0.19% rose 0.6% in midday trading Monday, to outperform its peer group but underperform the broader stock market, after Standard & Poor's revised up its outlook on the banking giant's credit rating to "positive" from "stable." The credit rating agency also affirmed A- long-term rating for the holding company and the A+ long-term rating for the operating company.
