The Nikkei, up 57 percent this year, has further to climb in 2014 because of Japanese Prime Minister Shinzo Abe's policies, Dennis Gartman said Monday.
"Abenomics is going to be working. I think you're going to end up seeing economic activity in Japan picking up rather dramatically," he said. "But the most important thing is the weakness of the Japanese yen is going to have a very, very strong impact upon Japanese equities."
The editor and publisher of The Gartman Letter told CNBC's "Fast Money" that the Bank of Japan's accommodative monetary policy would be a powerful catalyst.
