NEW YORK — Stocks slumped Tuesday on Wall Street after the International Monetary Fund predicted weaker world economic growth and as investors waited for what they expect to be lower corporate earnings.

The Dow Jones industrial average declined 110.12, or 0.8 percent, to 13,473.53. The S&P 500 dropped 14.40, a hair under 1 percent, to 1,441.48. The Nasdaq index lost 47.33, or 1.5 percent, to 3,065.02.

Investors were discouraged by an IMF report that projected the world economy will expand 3.3 percent this year, down from the previous estimate of 3.5 percent growth. Its updated forecast for 2013 growth is 3.6 percent, down from 4.1 percent.

The first 787 passenger plane made at Boeing South Carolina landed in India on Tuesday, a day after an Air India crew began the journey from Charleston International Airport. The flight included a stop for fuel in Germany.

The move followed criticism by Fortune managing editor Andy Serwer of Welch’s comments on Friday’s U.S. jobless report and a Reuters story quoting a money manager who described Welch’s statements as laughable, Fortune said.

PITTSBURGH — Aluminum maker Alcoa said Tuesday it lost $143 million in the third quarter due to charges, but otherwise topped expectations. The loss compares with a $172 million profit a year ago.

Excluding $175 million in charges, Alcoa earned $32 million. Revenue fell to $5.83 billion from $6.42 billion but still topped analyst forecasts.

Alcoa, which has a smelter near Goose Creek, has been challenged by the global manufacturing slowdown which hurt aluminum demand.
