Roth Capital analyst Philip Shen upgraded TPI Composites to Buy from Neutral with a price target of $28, up from $23. Near-term, Shen says there may be downside potential from COVID-19, but despite this, believes investors should take advantage of the recent weakness in the stock to accumulate shares.The analyst sees a "reasonable" path for TPI to reach its 12% EBITDA margin target over time. Shen says he became incrementally more positive on TPI at the recent analyst day, and looking ahead, continues to like the company's position within the industry.
