How the major stock indexes fared on Tuesday

Mixed signals on the world economy tugged on major stock indexes Tuesday.

The country's largest fertilizer company, Mosaic, said weak demand from China and India have hurt its profits. Mosaic, Dupont and stocks of other companies in the materials industry fell. But utilities and health care stocks, where investors often retreat in a slow-growing economy, helped pull the Standard & Poor's 500 index above the break-even mark.

The Dow Jones industrial average fell 32.75 points, or 0.2 percent, to close at 13,482.36.

The S&P 500 index rose 1.26, or less than 0.1 percent, to close at 1,445.75.
