NEW YORK, July 1 (Reuters) - Gold prices dropped below $1,200 an ounce on Thursday as a global equity-market slump and disappointing U.S. economic indicators prompted investors to dump the metal in a technical sell-off.
Bullion's 3.5 percent losses on Thursday was the biggest one-day drop since February.
Silver and platinum group metals also tumbled as signs of a slowing economic recovery and lackluster U.S. auto sales hurt the investment appeal of the industrial metals.
"What you are seeing is clearly a nervous feeling about all assets, whether they be tangible or intangible, paper or not. The overall mood is bearish and metals may not be the safe haven that you can just bank on," said Scott Meyers, senior analyst at New York-based Pioneer Futures.
Gold held up firm in the last two days in the face of heavy losses in the stock markets. However, gold's eventual decline versus the S&P 500 index on Thursday was similar to a pattern back in May. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

"Usual story -- selling first as people need cash... and then further down the road, the gold as a currency demand will kick in."

GOLD'S UP-TREND BROKEN
