Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Momenta (MNTA) downgraded to Equal Weight from Overweight at Barclays with analyst Douglas Tsao citing the likelihood of generic manufacturers, most notably Mylan (MYL), winning approval for generic Copaxone in the coming months. He lowered his price target for the shares to $17 from $20. 2. Zoe's Kitchen (ZOES) downgraded to Neutral from Outperform at Baird with analyst David Tarantino saying he believes the near-term risk profile looks elevated amid signs of sluggish comps for similarly positioned chains and an uptrend in input costs. Tarantino lowered his price target to $20 from $25 on Zoe's Kitchen shares. 3. Arista Networks (ANET) downgraded to Neutral from Buy at DA Davidson with analyst Mark Kelleher citing valuation with the shares up 60% since his initiation in January. 4. Synchronoss (SNCR) downgraded to Underperform from Neutral at Credit Suisse with analyst Michael Nemeroff citing AT&T's (T) recent announcement that it will be closing the personal cloud "Locker" storage service offering powered by Synchronoss on August 3. 5. Centene (CNC) downgraded to Neutral from Overweight at JPMorgan with analyst Gary Taylor citing valuation with the shares up 32% since December 2016. The stock reflects very little probability of Senate Medicaid cuts or block grants, Taylor tells investors in a research note. He keeps a $75 price target for the shares.
