News Summary: S&P can't excite, leaker can

News Summary: Investors yawn when S&P praises economy; leaker news sends Booz Allen lower

AN UNEXCITING OUTLOOK: The Standard & Poor's ratings agency, which sent the stock market into a tailspin in August 2011 when it cut its credit rating on the U.S. government's long-term credit, on Monday raised its outlook on the U.S. rating. Investors, however, hardly reacted.

THE SCORECARD: major stock indexes flitted between small gains and losses throughout the day. The Dow Jones industrial average and the S&P 500 ended slightly lower. The Nasdaq composite index ended slightly higher.

THE LEAKER AND THE STOCK MARKET: Shares of consulting firm Booz Allen Hamilton dipped after an employee, Edward Snowden, stepped forward as the person who had leaked information about the U.S. government's data-collecting programs.
