Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Under Armour (UA, UAA) downgraded to Underperform from Buy at Buckingham, to Market Perform from Outperform at FBR Capital, and to Hold from Buy at Evercore ISI. 2. AMC Entertainment (AMC) and IMAX (IMAX) were downgraded to Neutral from Outperform at Credit Suisse, while Regal Entertainment (RGC) was downgraded to Underperform from Neutral. 3. UPS (UPS) downgraded to Market Perform from Outperform at BMO Capital with analyst Fadi Chamoun saying the company's fourth quarter results were "weak," while it lacks positive catalysts in the near-term. 4. Corning (GLW) downgraded to Market Perform from Outperform at Bernstein with analyst Alberto Moel citing valuation. 5. Mobileye (MBLY) downgraded to Equal Weight from Overweight at Morgan Stanley with analyst Adam Jonas saying he is positive on ADAS market growth but also sees more rapid commoditization pressuring margins. Jonas expects the pace of growth to be driven by affordability and increased competition, leading to a larger market opportunity, but lower margins and reduced OEM dependency on one dominant technology supplier. Further, the analyst believes Mobileye will need to increase its R&D capacity and internal human resources in order to remain a long-term key player in the industry.

As previously reported, Credit Suisse analyst Omar Sheikh downgraded National CineMedia (NCMI) to Underperform from Outperform as he believes 2017 will be a tough year for cinema advertising, which suggests there could be limited scope for the company's inventory utilization and CPMs to grow. The analyst lowered his price target on the shares to $13 from $21. He also downgraded AMC Entertainment (AMC), Regal Entertainment (RGC) and IMAX (IMAX).
