I am no expert but think Vittera is a good company but expensive. Adm has a nice dividend one can accumulate while waiting for growth. If adm were to trade at the current and forward p/e of Viterra is would be trading between $44.85-$50.80. Having said that adm at $45 within 6 mos. would not surprise me. In the future i think adm might trade at a higher p/e.
I agree that adm is a complex company with a lot of variables. This is why ones opinion of management is very important. Having said that even with mediocre managment adm should ride the tide up this next decade.
