Forget stocks, forget gold, forget oil, because for Dennis Gartman, there is one commodity every investor needs to own: aluminum.
"Buy aluminum first," Gartman said. "That's the best commodity trade out there."
In an interview with "Futures Now" on Tuesday, the Commodities King said aluminum is not only the best way to play the record run in stocks, but could also be the best proxy for investing in the global recovery.
"Everyone laughed at me when I started buying aluminum nine months ago," joked Gartman. "You are going to see a larger off take of aluminum going into automobile production. It's the easiest way to meet EPA requirements for mileage is to make the automobiles and trucks lighter, and aluminum does that relative to steel and you're going to be selling, we're going to be selling, everybody's going to be selling a lot of automobiles for the Chinese."
