The further growth of Norsk Hydro's earnings depends on aluminum prices. The global aluminum industry is in anticipation of cutting China's capacity to reduce the country's pollution levels, which could provide an added boost and support primary aluminum price rise. However, I haven't seen a major impact from the capacity cuts in China's aluminum production in 2017. The Company's mine-to-mills strategy will fully work, if demand keeps expanding across all aluminum-industry applications. So my neutral recommendation reflects the current uncertainty about the production capacity in China.
