Steel-sector stocks have been taking investors on a roller-coaster ride lately. At one point this year, they had climbed a whopping 36%, but they are now down 16% for the year.

Global investors seeking undervalued markets might want to look at Russia, China, India, Malaysia, South Korea or Brazil. And if they want to avoid overvalued markets, they’d be best to eschew Italy, the United States, Japan, Canada, Switzerland, or Germany.
