Gold is the leader of the ETF pack, as these precious metal funds are dominating the rest for the past three and six months, Investors Business Daily reports.
The StreetTracks Gold Trust and the iShares Comex Gold Trust have gained more than 13% just in the past month.
"It's surprising that we haven't seen any big inflow into the two gold ETFs," said Charles Biderman, chief executive of TrimTabs Investment Research.
In the first quarter of this year, $2.2 billion was invested into the two gold ETFs, but in the second quarter that pace slowed, as $200 million went in.
"There's no question some individual investors are moving into commodities," said Biderman. "But in terms of actual dollars, it's the hedge funds and large pension managers who are making the biggest dent in gold markets."
