Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. La Jolla (LJPC) downgraded to Underperform from Buy at Jefferies by analyst Eun Yang, who said her critical care physician and Pharmacy & Therapeutics committee member polls on Giapreza point to a "likely modest" sales opportunity relative to consensus expectations. In the absence of a potential buyout, downside risks in the stock are greater relative to upside potential in the next two-to-three years. 2. Natural Grocers (NGVC) downgraded to Underweight from Equal Weight at Barclays by analyst Karen Short, who believes upside can only be generated should comps rise to positive low single digits with stable margins, an activist emerges, or if the company were to be viewed as a potential takeout candidate. She believes these scenarios are unlikely, "at least for now." 3. EQT Midstream (EQM) and EQT GP (EQGP) downgraded to Sector Perform from Outperform at RBC Capital by analyst TJ Schultz, who derived his rating from his probability scale around the midstream business, assigning a 65% chance that EQT GP is the surviving entity post midstream simplification and a 30% chance that EQT Midstream Partners is the surviving entity. 4. Tallgrass Energy GP (TEGP) downgraded to Equal Weight from Overweight at Barclays by analyst Christine Cho, who said her analysis suggests a Tallgrass Energy GP acquisition of Tallgrass Energy Partners (TEP) is the most likely scenario. She valued Tallgrass Energy GP at $25 in this scenario. 5. Unisys (UIS) downgraded to Neutral from Positive at Susquehanna. This list is just a portion of The Fly's full analyst coverage.
