‘Ridiculously Bearish for Miners’: Gartman

The move in the U.S. dollar bodes poorly for gold and worse for mining companies, Dennis Gartman of The Gartman Letter said Thursday on CNBC.

"It broke out against every currency out there, even the Aussie, so this is a dollar move, and a dollar move to this sort of strength cannot be construed as being anything other than bearish for the metals and ridiculously bearish for the miners," he said.

The U.S. dollar surpassed the key 100 yen-level for the first time in four years on stronger U.S. data but also amid speculation about a report on Japanese capital flows.

On "Fast Money," Gartman said that the dollar's move higher would be bearish for gold, copper and miners.

"In an environment such as this, the miners have always – especially the gold miners – have underperformed gold," he added. "They may even do worse going forward."

Gartman also said that he would sell the long bond following that market's tumble.

"I'm going to continue to buy the note after today's performance," he added. "I thought that was a very poor performance."
