NEW YORK (AP) -- A steep fall in commodity prices pulled down energy and mining stocks for a second day in a row on Monday.
Gold plunged below $1,400 an ounce for the first time in two years as a sell-off in metals continued from last week. A slowdown in China also pushed down the price of copper, and the price of crude oil hit its lowest level since mid-December.
The Dow Jones industrial average was down 68 points at 14,796 shortly before midday Monday, a drop of 0.6 percent. Caterpillar led the Dow lower.
Mining stocks fell sharply. Freeport-McMoRan Copper & Gold lost 7 percent.
The Standard & Poor's 500 index fell 10 points to 1,578, a loss of 0.6 percent. The Nasdaq composite fell 22 points, or 0.7 percent, to 3,272.
