Wall Street ends lower; focus shifts to earnings

NEW YORK -- Stocks are ending lower on Wall Street after a weak forecast for global growth from the International Monetary Fund. Now investors turn their attention to corporate earnings reports.

The Dow Jones industrial average is ending the day down 110 points at 13,473. The Standard & Poor's 500 index finishes down 14 points at 1,441. And the Nasdaq composite index is down 47 at 3,065.

Aluminum company Alcoa is set to report its results first. Analysts expect earnings for Standard & Poor's 500 companies to be lower than a year ago _ the first time that has happened in almost three years.

About four stocks fell for every one that rose Tuesday. Early figures show trading volume was about average, about 3.2 billion shares.
