July 23 (Reuters) - Wall Street fell for the third straight day on Thursday following disappointing results and forecasts from companies including 3M and Caterpillar, adding to U.S. profit concerns.

The manufacturing companies' declines helped push the Dow Jones industrial average back into the red for the year. Also hurting the Dow was American Express, down 2.6 percent at $76.95 after revenue missed expectations.
