On Friday, he reiterated his belief that it is still a bull market.
"It's the smart guys, the pros who keep trying to call tops and every time we try to do it, it makes us look sillier and sillier," Gartman said.

Gartman suggested investors look into steel, cooper and aluminum, "basic things that are incumbent in normal economic growth around the world."
As for when the market will top, Gartman was through with predictions, for now.
