FSLR Stock Heads For Its Worst Week In Over A Month — Roth Says US Polysilicon Crackdown Could Provide A Tailwind

First Solar (FSLR) shares fell 11% on Thursday, heading for their worst week in six weeks. Roth Capital cited concerns over solar-module pricing but sees the recent weakness as a buying opportunity. The Commerce Department's crackdown on polysilicon stockpiling could benefit domestic solar manufacturers. FSLR reported mixed Q2 results with revenue down 4% to $1.06B but earnings up 23% to $3.92 per share.
