* Dollar rebounds on short covering, gold retreats from highs
* SPDR holdings <XAUEXT-NYS-TT> flat as investor demand weak
By Chikako Mogi
TOKYO, Sept 14 (Reuters) - Gold prices erased earlier gains and fell on Monday, as the dollar rebounded on short-covering and dragged down other commodities' prices and equities.
Gold prices topped $1,000 per ounce last week and closed above that level on Friday for the first time since March 2008, as investors sold the dollar to buy higher-yielding and riskier assets on growing optimism about the outlook for the global economy.
Some traders have questioned whether gold's current high levels can be sustained, as much of its recent rally has been driven by funds emboldened by favourable technical charts although physical demand and demand from individuals remain weak.
"The dollar's rebound was the trigger," Ben Westmore, commodities economist at National Australia Bank, said of the gold's retreat. "Gold may be pressured by some unwinding of holdings by funds."
Westmore said investors were likely adjusting their outlook for demand, refocusing on the view that growth was likely to wane after stimulus measures from governments fade and that a V-shaped recovery is unlikely.
He added that investors may be reassessing commodities' stockpile data that suggests fundamentals remain weak, as well as their attitude towards China, whose imports have helped push up prices across the markets.
But he said while growth in demand may slow, this new round of market correction was unlikely to dent demand.
