US breakfast cereal group Post Holdings kicks off a relatively quieter week of results with its half-year numbers on Monday. On Tuesday, meat giants Marfig and JBS will report on how it fared in the first three months of the year - as will Wal-Mart on Thursday. The week also includes an international conference in the Netherlands looking at the sustainable cultivation of soy.

Half-year results are due in from Post Holdings, the US breakfast cereal group behind brands like Grape Nuts and Honey Bunches of Oats. Competition for a place on US breakfast tables is growing and the category is one of the more challenging in the industry. Post's executives will also be quizzed on the company's acquisition of a clutch of private-label and branded assets from Hearthside Foods this week.
