Precious metals and exchange traded funds (ETFs) have been all over the map lately; demand is up for some, down for others and prices are struggling to find their way amid the market volatility. One thing is for certain: they’re attracting attention.

Gold has been defying the fundamentals, ignoring its usual correlation with down markets. SPDR Gold Shares (GLD) is down 16.9% in the last month, while the S&P 500 is down 15.9%. Gold is generally seen as a safe haven, so investors run for cover with the metal in down markets. But a strengthening dollar has turned the tables on that thinking for the time being, as gold typically moves opposite the greenback.

Gold is continuing to decline today, as the dollar shows new vigor and oil prices slump, reports Moming Zhou for MarketWatch.

Copper prices are falling on lower demand. The metal is often used for electrical wiring and pipe, but the global decline in homebuilding has put a dent in the need for it for the time being, according to MarketWatch. Copper sales at one company, Newmonth (NEM), fell 84% in the third quarter.

Chile, the world’s largest copper producer, saw 10.3% less output in September from a year earlier. It’s the third consecutive month year-over-year that production declined, reports Reuters.

A platinum producer in South Africa has cut its annual output forecast for the third time. Lonmin Plc said the full-year platinum output from its concentrators has fallen 16% in the year ending Sept. 30. The company had expected production to improve going into 2009, says Ron Derby for Bloomberg.

South African mines have been plagued all year by production interruptions, caused by a failure of the state-owned power company to meet demand.

Platinum prices have fallen 46% this year, but has gained along with palladium in recent days as precious metals demand rises, says Halia Pavliva for Bloomberg. Until recently, palladium was down 51% for this year.

Car makers account for 60% of global platinum use, and a struggling auto industry is leading lower demand for the metal.
