The South American grains powerhouse is a major international corn, soybean and wheat supplier as well as the world's top exports of soymeal livestock feed.

The uptrend from $1.2040 looks incomplete. It seems to have adopted an impulsive wave mode. A small triangle is contracting to a point. It is a bullish continuation pattern.
It is too early to confirm a reversal of the uptrend, simply based on the drop from the Dec. 18 high of $52.48. Resistance is at $51.83, a break above which could lead to a gain to $52.15.
