Take a look at some of Friday's midday movers:
Homebuilders got a lift from noted housing analyst Ivy Zelman. Zelman upgraded several stocks including KB Home, M/I Homes, Beazer Home and Owens Corning to a "buy" rating. In a telephone interview, Zelman noted that she likes stocks that are "long land" and says that California is especially strong.
iShares Silver Trust was lower. The price of silver futures have been cut roughly in half since hitting its high price back in April, 2011.
Herbalife was lower despite an upgrade from noted D.A. Davidson analyst Tim Ramey. Ramey had been an outspoken bull on shares of Herbalife until he downgraded the stock earlier this week on concerns about the withdrawal of KPMG's audit opinions for the past three years. On Friday, Ramey "re-established" HLF at a "buy" with a price target of $78 per share.
And on a down day, Harris Corp. was the worst performer on the S&P 500. Following the satellite operator's warning about the impact of sequestration on earnings, JPMorgan cut its price target on Harris to $39 from $45, with an "underweight" rating.
