The gold bulls include David Einhorn, founder of hedge fund Greenlight Capital, who last year came under the spotlight for his short selling of shares in Lehman Brothers, after arguing that the bank did not have enough capital to offset its exposure to falling property prices. Other funds looking at gold include Eton Park and TPG-Axon, investors said.

Their belief in bullion is being expressed even as gold prices have retreated from last month's break above the $1,000 an ounce level. Spot gold in London closed last Friday at $939.10, after falling last week to $900.95 an ounce.

Investors such as Mr Einhorn are turning to gold because they are worried about the response of the US Federal Reserve and other central banks to the global economic crisis. A bet on gold is essentially a bet against all paper currencies.
