Goldman's Tuesday bear call on agricultural commodities has implications for Deere (DE -2.7%) which gets a downgrade to Sell from Neutral. Analyst Jerry Revich says "recovering commodity inventories point to lower U.S. farm income and capex." As recently bearish Barron's notes (channeling Wells Fargo's Andrew Casey) "as goes the North American corn crop, so goes DE's stock price." For their part, GS says only a "major weather shock" could keep corn crop (CORN +0.1%) prices "near their current levels." Price target: $85 from $98.
