NEW YORK (AP) -- U.S. stocks were falling for a second day in midday trading Tuesday. Oil prices dropped further and the head of the International Monetary Fund sounded downbeat on the outlook for the world economy.
Disney fell after the company's expected successor to CEO Bob Iger announced he was leaving the company. Allergan plunged after the Treasury Department announced new tax rules that would make its merger with Pfizer more difficult.
KEEPING SCORE: The Dow Jones industrial average lost 116 points, or 0.7 percent, to 17,622 as of 12:25 p.m. Eastern. The Standard & Poor's 500 index fell 20 points, or 0.9 percent, to 2,047 and the Nasdaq composite fell 46 points, or 1 percent, to 4,845.
GLOOMY OUTLOOK: Christine Lagarde, the head of the IMF, warned in a speech that "the recovery remains too slow, too fragile." She said the world economy isn't in a crisis but that slow growth risks becoming ingrained as a "new mediocre." She noted the outlook for the next six months has weakened, suggesting the IMF may be revising its forecasts lower.
GLOBAL DECLINE: European and Asian markets closed broadly lower. Japan's benchmark Nikkei 225 index lost 2.4 percent, hit hard by a rise in the yen. South Korea's Kospi fell 0.8 percent and Hong Kong's Hang Seng sank 1.6 percent. In Europe, Germany's DAX fell 2.6 percent, France's CAC-40 fell 2.2 percent and the U.K.'s FTSE 100 fell 1.2 percent.
THE TAX MAN COMETH: Allergan fell $45.37, or 16 percent, to $232.19. The U.S. Treasury Department announced new tax rules to discourage what are known as corporate inversions, which is when a U.S. company mergers with a foreign company for tax purposes. Allergan was currently in the process of doing an inversion with U.S. drug giant Pfizer. Shares of Pfizer rose 69 cents, or 2.2 percent, to $31.40.
LET (HIM) GO, LET (HIM) GO: Disney fell $2.27, or 2.3 percent, to $96.40. The media giant said late Monday that Tom Staggs, the heir apparent to the company's current CEO, would step down from the company. Iger said he plans to retire in 2018.
