JPMorgan analyst Ann Duignan upgraded Archer Daniels Midland (ADM) to Neutral from Underweight and raised her price target for the shares to $48 from $42. The analyst keeps an Overweight rating on Bunge (BG) while lowering her price target for the shares to $82 from $90. Duignan expects Q2 to be "very strong" for Archer Daniels and "very challenging" for Bunge. The analyst, however, views Archer Daniels' stock as fairly valued and sees limited downside to Bunge's valuation in the near term. China's tariffs on U.S. soybeans have weighed on prices and driven record U.S. soy crush volume and margins, which is positive for ADM, Duignan tells investors in a research note. Meanwhile, trucker strikes in Brazil are likely to have weighed on Bunge's Q2 results with shutdowns impacting all segments, the analyst adds.

Bunge is down -6.6%, or -$7.20 to $102.42.
