SunPower's (SPWR) stock was cut in half after the solar bubble burst. Now it could double, with earnings growing 40-50%. The US Senate tried to attach an extension of the solar tax credit to the economic stimulus bill, but it failed to pass. While an extension could be reintroduced anytime, it most likely will be part of a package considered in the 4Q that would extend the wind and solar tax credit and the R&D tax credit, and apply a "patch" to the dreaded alternative minimum tax. "There's so much bipartisan support for the wind and solar package" that there's an 85-90% chance it gets passed by yr end, says Daniel Clifton, of Strategas Research Partners.
