As reported earlier, SunTrust analyst Keith Hughes has downgraded residential construction names Installed Building Products (IBP), Building Materials Holding (BMCH), TopBuild (BLD), and Builers FirstSource (BLRD) to Hold from Buy. The analyst also lowers their respective price targets to $41, $18, $55, and $13, from $42, $22, $70, and $17. Hughes cites these companies' recent stock price appreciation of 20%-25% relative to 10% rise for the S&P, his maintained outlook for housing market weakness, and his view that any rebound in housing from lower interest rates will be modest without a Fed rate cut. The analyst adds that valuation on Builers FirstSource and Installed Building Products is now "about average" and that of the other two companies "too low", though he still expects the latter two stocks to trade "flattish".
