Another industrial winner turned lower amid international trade woes and a disappointing outlook for the second half of the year.

Action Alerts PLUS holding DowDuPont Inc.  fell $1.51, or 2.2%, to $66.45 around 2 p.m. as trade concerns weighed on investors and analysts raised concerns over lighter-than-anticipated Ebitda guidance.

Earlier Thursday, Aug. 2, the chemicals producer posted stronger-than-expected second quarter earnings and said year-on-year savings from its $130-billion-merger would help boost sales and profits.

But the company guided for 2018 Ebitda of about $3.75 billion, below consensus estimates of $3.89 billion. 

"While the beat was bigger than expected, the guide may temper enthusiasm and keep investors sitting on the sidelines, despite the compelling longer-term story and cheap valuation," BMO Capital Markets Corp. analysts John McNulty and Joel Jackson said in a note to clients Thursday. 

DowDuPont said adjusted non-GAAP earnings for the three months ending in June rose 41% to $1.37 per share, topping the consensus forecast of $1.30. Net sales, the company said, rose 17% to $24.2 billion, with volumes and local price gains recorded across all of its divisions and regions. The group said it sees third quarter sales rising 10% and operating earnings rising 12% even as it cited "discrete" headwinds related to currency movements and higher raw materials costs.

"Volume growth, local price gains and operating margin expansion were the key highlights, reflecting a clear focus from the businesses on execution," said CEO Ed Breen. "Our new product launches are resonating with customers, resulting in strong demand across each of our targeted end-markets. These are indicators that our three divisions are making a difference in the marketplace and for shareholders."

"We have great momentum and our employees are enthusiastic about the future of our intended industry-leading companies," he added.

Materials science sales drove the quarterly increase, rising 18% on a pro-forma basis to $12.6 billion, while agricultural sales were 23% higher at $5.7 billion. The group said savings from the $130-billion-merger of Dow Chemical and DuPont last September were $900 million over the three-month period, a figure it expects to rise to $1.4 billion by the end of the year.
