KB Home (KBH) downgraded to Sell from Hold at Evercore ISI with analyst Stephen Kim saying shares appear overvalued relative to his $14 price target, especially since it should not benefit as much from lower U.S. corporate tax rates as peers. 3. Northrop Grumman (NOC) downgraded to Hold from Buy at Jefferies with analyst Howard Rubel saying he's become more selective for the Aerospace & Defense Electronics space with valuations and expectations higher post the U.S. election.

Magellan Midstream (MMP) downgraded to Outperform from Strong Buy at Raymond James with analyst Darren Horowitz citing valuation and saying its ultra-defensive characteristics, may result in shares lagging peers as oil prices continue to recover throughout 2017 and beyond.
