(Bloomberg News) Gold, in the 11th year of its longest winning streak in at least nine decades, is poised to enter a bear market, according to Dennis Gartman, who correctly predicted the slump in commodities in 2008.

The metal, which traded at $1,666.30 an ounce at 2:43 p.m. in London, may decline to as low as $1,475, the economist wrote today in his Suffolk, Virginia-based Gartman Letter. He sold the last of his gold yesterday. Bullion has already dropped 13 percent from the record $1,921.15 reached Sept. 6 and $1,475 would extend that to more than 20 percent, the common definition of a bear market.

"Since the early autumn here in the Northern Hemisphere gold has failed to make a new high," Gartman wrote. "Each high has been progressively lower than the previous high, and now we've confirmation that the new interim low is lower than the previous low. We have the beginnings of a real bear market, and the death of a bull."

The metal typically moves inversely to the dollar, which today reached a two-month high against the euro after Fitch Ratings and Moody's Investors Service said yesterday that a European Union summit last week offered little help in ending the region's debt crisis. Bullion is still 17 percent higher this year and holdings in gold-backed exchange-traded products are at a record, a hoard now valued at $126.5 billion.

Gold's performance this year compares with a 2.8 percent advance in the Standard & Poor's GSCI gauge of 24 commodities, in which it is the third-best performer behind gasoil and cattle. The MSCI All-Country World Index of equities retreated 9.8 percent and Treasuries returned 9.2 percent, a Bank of America Corp. index shows.

The slump in equities spurred some investors to sell their gold to cover losses. Open interest, or contracts outstanding, in gold futures traded on the Comex exchange in New York, fell to 427,756 contracts, from 546,601 in July, bourse data show.

"So much damage has been done to the psychology of the market in the past week and so many late longs have been caught off guard that we think wholesale liquidation, and perhaps forced liquidation, shall be the outcome," Gartman wrote.

ETP investors are increasingly bullish. Holdings in the products climbed 3.8 metric tons to an all-time high of 2,360.5 tons yesterday, according to data compiled by Bloomberg. That's equal to more than 10 months of global mine supply and greater than the reserves of all but four of the world's central banks, which are expanding holdings for the first time in a generation.

Hedge funds and other money managers boosted bets on higher futures prices for the first time in three weeks. Net-long positions in gold futures and options rose by 3.5 percent to 151,347 contracts in the week ended Dec. 6, U.S. Commodity Futures Trading Commission data show. That's still down 40 percent since the beginning of August, when positions were at the highest level since at least June 2006, the data show.

While the drop below $1,670 spurred more physical buying from India and South East Asia, the demand increase is from "relatively low" levels, Standard Bank Plc wrote today in a report. UBS AG said its physical flows to India yesterday were "well above" average and the most since Oct. 20.
