Enphase Energy is trading at $30.27, down 4.19%, amid analyst target cuts and U.S. residential-solar concerns ahead of its October 27 third-quarter report. - BMO lowered its target to $28 from $37; Roth cut its target to $55 from $85. - Analysts expect revenue near $304 million, down about 26% year over year. - Coverage points to pre-earnings caution, not a confirmed October 26 announcement; major indexes were higher, so broad-market weakness does not explain the decline.
