Stocks sank sharply Tuesday morning, driving major indexes to their lowest point since early September, after big-name companies reported weak quarterly earnings and lowered their expectations for the rest of the year.

The Dow Jones industrial average sank 245 points, or 1.8 percent, to 13,100. The Standard & Poor's 500 index fell 24 points, to 1,409. The NASDAQ composite index was off 39 points, at 2,977.

The day was shaping up to be among the worst of the year on Wall Street. The Dow's biggest decline was 274 points, on June 1.

3M, which makes everything from Scotch tape to coatings for LCD screens and is an economic bellwether, reduced its profit expectations for this year because of "current economic realities."

Some of the disappointing revenue is because of weakness in foreign markets. Multinational companies are having a hard time selling to Europe, which is struggling under a debt crisis and a spreading recession.

The red-hot growth enjoyed by emerging markets like China and India is also slowing, and many businesses that had relied on growth there to offset weak U.S. consumer demand are being forced to come up with new strategies.

"The recession in Europe is very real," said Bernard Schoenfeld, senior investment strategist for Bank of New York Mellon Wealth Management in New York. "It's not going to disappear very quickly, and it will certainly negatively affect earnings of exporters in the United States."

Financial analysts have predicted that earnings for S&P 500 companies for July through September would be lower than the year before, breaking a three-year winning streak.
