Bernstein analyst Jonas Oxgaard believes that Mosaic's (MOS) acquisition of Vale's (VALE) fertilizer assets, announced this morning, is positive for Mosaic. The analyst says that the deal is in-line with the company's strategy of focusing on phosphate and South America. The deal also "further differentiates" Mosaic from Potash (POT)/Agrium (AGU), which is concentrating on potash/nitrogen and North America, according to the analyst. He sees the deal as positive for Potash/Agrium as well. He keeps a $31 price target and an Outperform rating on Mosaic.
