As previously reported, SunTrust downgraded Chemours to Hold from Buy as analyst James Sheehan said he believes the company's "dramatic" market share losses under its Value Stabilization pricing strategy are unlikely to be recovered until 2020 or beyond. He also doubts European governments will be able to stem the flow of illegal, low-priced refrigerant imports in a timely way and expects investors will continue to discount worst case environmental liability scenarios, Sheehan tells investors. Given this trio of areas of concern, the analyst cut his price target on Chemours shares to $16 from $36.
