Shares of farm-supply companies came under further pressure Tuesday following disappointing quarterly results from fertilizer maker Mosaic Co. amid an escalation in the U.S.-China trade fight.
Farm-supply companies have fallen this week after Beijing said it would suspend all imports of U.S. agricultural goods, a retaliatory measure to President Trump's decision to impose new tariffs of 10% on roughly $300 billion of imports from China.
In addition to trade woes, fertilizer companies have been hurt by declining sales as midwestern farmers faced persistent wet weather this past spring.
Mosaic's stock slid 6.7% Tuesday to close at $22.02, its biggest one-day drop since May 7, after the company cut its full-year earnings forecast following severe flooding in the U.S. Farm Belt.
The losses spread to other fertilizer makers including Nutrien Ltd., which fell 3.2%.
Meanwhile, U.S. farm-equipment maker Deere & Co. and chemical companies Bayer AG and Corteva Inc. have each dropped at least 3.7% this week.
Heightened tensions between the world's two biggest economies have revived worries that the trade battle could hinder the decadelong U.S. economic expansion, some analysts and investors said.
Trade and weather have already been weighing on the incomes of U.S. farmers, which have been hurt by lower overseas purchases of U.S. corn, soybeans and other crops. This is expected to crimp sales of fertilizer and tractors.
These stocks may not recover soon.
"We don't think a trade deal will get done before 2020, therefore we're recommending that investors stay away from trade-sensitive areas of the market such as agriculture even though these companies are getting cheap, " said Matthew Granski, director of strategy at Miracle Mile Advisors in Los Angeles, which has $1.7 billion in assets under management.
