Gold extended its slump Tuesday, as a stronger dollar and surging stock market helped tug the price of the precious metal lower.
Gold for June delivery dropped $9.80 to settle at $1,424.50 an ounce on Tuesday. Gold prices have lost 3 percent this month.
Until recently, many investors bought gold as a form of protection. They expected it to rise when stocks, bonds and the dollar fell. But this year, the stock market's rally and the dollar's climb this year have lured investors out of gold.
Silver and copper also dropped Tuesday.
Silver for July delivery lost 31.7 cents to settle at $23.379 an ounce. Copper for July fell 7.15 cents to $3.288 a pound.
Platinum and palladium surged more than 1 percent as traders anticipated tighter supplies. Workers at Lonmin, one of South Africa's largest platinum producers, went on strike Tuesday. During a strike at one of Lonmin's mines last August, police shot dead more than 30 workers.
Platinum for July rose $17.40 to $1,501.90 an ounce. Palladium for June rose $8.45 to $727.15 an ounce.
