NEW YORK - U.S. copper futures lost more than 4 percent of their value early Monday as a sharp sell-off in equities drove investors to seek safer-haven assets such as the dollar and gold, analysts said.

Copper for May delivery HGK9 plunged 9.00 cents, or 4.1 percent to $2.1040 a lb. on the New York Mercantile Exchange's COMEX division. Further selling took the benchmark contract down to an early session low of $2.1025. (Reporting by Chris Kelly)
