Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. CBS (CBS), AMC Networks (AMCX), and Discovery (DISCA) downgraded to Sell from Neutral at UBS. 2. NVIDIA (NVDA) downgraded to Underperform from Market Perform at Wells Fargo with analyst David Wong saying renewed competition from AMD (AMD) in graphics and Intel (INTC) in coprocessors "could create headwinds to growth" and possibly limit the company's ability to beat expectations in the near term. 3. Chipotle (CMG) downgraded to Equal Weight from Overweight at Morgan Stanley with analyst John Glass saying checks indicate the sales recovery will be more prolonged than the market believes, and potentially more costly, as the company likely needs to ramp up marketing to attract customers back. 4. Harley-Davidson (HOG) downgraded to Hold from Buy at Stifel with the firm citing valuation and its belief that the company's U.S. retail motorcycle sales dropped 2% last quarter. 5. Teva (TEVA) downgraded to Neutral from Buy at Goldman with analyst Jami Rubin saying upside will be limited given Copaxone uncertainty and the company's elevated leverage.
