Shares of First Solar (FSLR - Get Report) were up by 0.34% to $29.64 on Monday morning, following a ratings increase to "neutral" from "underperform" at Credit Suisse. The firm has set a price target of $31 on the provider of photovoltaic solar energy solutions, above its previous price target of $25.

The upgrade comes on the potential of the Suniva Section 201 trade complaint succeeding as well as a 23% short interest in the company, TheFly noted.

On April 26 U.S.-based solar manufacturer Suniva filed a petition to have global safeguards placed within the U.S. International Trade Commission to protect the country's solar industry.
