Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Fossil (FOSL) downgraded to Underperform from Market Perform at Wells Fargo, with analyst Ike Boruchow saying Q4 sales missed expectations "despite a much hyped push into wearables" while Q1 trends suggest that reorder activity has been "extremely weak following their holiday sell-in." 2. Under Armour (UA) downgraded to Negative from Neutral at Susquehanna, with analyst Sam Posner arguing that 20% annual revenue growth is "a thing of the past for the foreseeable future." Poser tells investors that commentary by CEO Kevin Plank in the current "polarized political climate" make it "nearly impossible" to effectively build a cool urban lifestyle brand, noting that several stars reacted unfavorably to his comments. 3. Hologic (HOLX) downgraded to Neutral from Buy at BofA/Merrill, with analyst Derik de Bruin saying the Cynosure (CYNO) acquisition enhances growth but at lower margins. The analyst said Cynosure adds new higher growth revenue but margins and cash flows are low relative to Hologic's and will not fully offset dilution from the recent blood screening divestiture. 4. Aircastle (AYR) downgraded to Market Perform from Outperform at Cowen by analyst Helane Becker, who said the company's growth rate is slowing as aircraft acquisition is more competitive. Aircastle was also downgraded at FBR Capital to Market Perform from Outperform. 5. Convergys (CVG) downgraded to Hold from Buy at SunTrust by analyst Frank Atkins, who said top line growth may be limited near-term due to increased uncertainty driving weakness in the demand environment.
