Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Facebook (FB) downgraded to Sell from Hold at Pivotal Research with analyst Brian Wieser saying the shares are not factoring in risks to the company's growth following their "remarkable run" this year. 2. Ulta Beauty (ULTA) downgraded to Perform from Outperform at Oppenheimer with analyst Rupesh Parikh saying softer commentary from L'Oreal on its earnings call, increasing promotional activity from the department store channel, and more difficult year-over-year comparisons "could now signal a potentially more challenging beauty backdrop going forward." 3. Hertz (HTZ) downgraded to Underweight from Equal Weight at Barclays with analyst Brian Johnson saying fundamentals may have bottomed, but the stock is ignoring the challenges ahead in the company's earnings recovery following the nearly 100% rally since June 21. 4. Citi (C) downgraded to Market Perform from Outperform at BMO Capital with analyst James Fotheringham citing valuation and lack of catalysts. 5. Visteon (VC) downgraded to Neutral from Buy at UBS with analyst Colin Langan saying the risk/reward is more balanced with the shares up 60% over the last year.
