For traders long Corn and short Soybeans, this trade has been advantageous over the past month and six months. The stronger technicals of Corn, along with its aggressive push towards its 52-week high, support the continuation of this trade. However, Soybeans' YTD underperformance indicates that the longer-term mean-reversion argument has not yet materialized.

Conversely, those long Soybeans and short Corn are positioning for a value play. Soybeans have been the better performer YTD but have recently stalled, and investors are betting on Soybeans catching up while Corn exhausts near its 52-week highs. The weekly chart for Soybeans does not yet support this strategy, but the YTD outperformance suggests the fundamental support for Soybeans remains robust.

Key levels to monitor include Corn's 52-week high at 492.0, which is the primary resistance to watch. A break above this level would likely accelerate the pair trade further. For Soybeans, the weekly S2 pivot point at 1,151 is a critical level; a break below could trigger a move towards 1,136.
