BANGKOK — Asian stock markets rose Wednesday after the fourth-quarter earnings season got off to a positive start in the U.S. with aluminum giant Alcoa forecasting higher demand for 2013.
Demand for aluminum has been hurt by the weak global economy, but Alcoa predicted a 7 percent increase in demand this year, slightly better than the 6 percent increase in 2012. Because Alcoa makes aluminum for so many key industries, investors study its results for clues about the health and direction of the overall economy.
