Billionaire and international financier George Soros shook up the financial media with comments at the World Economic Forum a year ago, where he called gold the “ultimate asset bubble.”

He has since tempered those remarks, and according to recent filings, has bought gold — a lot of gold.

Soros’ fund took a position valued at $64 million in iShares Gold Trust (IAU), a bullion-holding exchange traded fund, according to a Securities and Exchange Commission filing by his firm dated Sept. 30. He bought five million shares with an estimated value of $12.80 each. IAU currently trades at $13.30.

“It’s all a question of where are you in that bubble,” Soros, 80, said in a recent speech, reported by Bloomberg News. “The current conditions of actual deflationary pressures and fear of inflation is pretty ideal for gold to rise.”

“The big negative is that too many people know this and a lot of hedge funds are very heavily exposed,” Soros said at the event, held on Nov. 15 in Toronto, Canada.

Soros made his name as the man who cornered the British pound in 1992, making $1 billion in the process. At the time he called gold the ultimate bubble, it traded at $1,087.10 an ounce. It sits at $1,359.35, up 25 percent in a year.
