Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Bluebird Bio (BLUE) downgraded to Buy from Conviction Buy at Goldman Sachs with analyst Salveen Richter saying rating change is is not driven by concerns around Bluebird's pipeline execution or emerging competitive threats. The analyst just believes appreciation of key aspects of his investment thesis are better reflected in the shares at current valuation levels. 2. Venator Materials (VNTR) downgraded to Neutral from Overweight at JPMorgan with analyst Jeffrey Zekauskas saying he believes lower prices and higher raw material costs for TiO2, coupled with higher capital expenditures, diminishes Venator's free cash flow outlook. 3. Antero Resources (AR) downgraded to Market Perform from Outperform at BMO Capital with analyst Phillip Jungwirth citing valuation. 4. New Age Beverages (NBEV) downgraded to Hold from Buy at Maxim. 5.
