Barclays analyst Michael Leithead raised his price target for Westlake Chemical to $82 from $90 while keeping an Overweight rating on the shares. The analyst believes Street estimates are too high primarily in Vinyls, driven by continued caustic soda decline and further headwinds from high-cost natural gas inventory. He sees these offsetting PVC price improvements and modest seasonal benefits in building products. However, the analyst cites tightening Chlor-alkali supply/demand fundamentals, above-average capital deployment, and Westlake's "supportive valuation" for his continued positive view.
