JPMorgan analyst Stephen Tusa recommends an automation pair trade of long Emerson (EMR), short Rockwell Automation (ROK). While fundamentals across the automation industry "remain relatively solid for now," the analyst sees potential for "material divergence" between these names as an opportunity, and he favors Emerson. Following the failed bid for Rockwell, Emerson's plans for share gain within marginal discrete markets should allow it to outperform "here from a low base, potentially at the expense" of Rockwell, Tusa tells investors in a research note.
