Investors can't be too bullish on either gold or copper, commodities trader Dennis Gartman said Monday.
"You can't find yourself being too terribly bullish of any of the metals at this point," he said.
Gold futures closed at $1,281.60, up 0.35 percent, while copper ticked up 0.18 percent to end the day at $3.03.
On CNBC's "Fast Money," Gartman sounded bearish on copper.
"Copper clearly has difficult fundamentals facing it," he said, expecting it to drop below $3 per pound.
"Gold needs fuel, needs monetary aggressiveness to push it up," Gartman added, noting that it wasn't receiving it.

"It only has one friend in the Bank of Japan, and if you're going to be long of gold, the only way to do it is to be long in yen terms," he said. "Anybody who holds gold in dollar terms finds himself in a very uncomfortable position."
In order for call a bottom in gold, Gartman said that he would need to see a few things happen first.
