Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Boeing (BA) downgraded to Underperform from Neutral at Buckingham with the firm saying at current levels, shares are priced for perfection and reflect optimistic free-cash-flow estimates. The firm's analyst expects Boeing shares to underperform on downward estimate revisions, a series of negative catalysts, and multiple compression. 2. Reynolds American (RAI) downgraded to Sector Perform from Outperform at RBC Capital. 3. Occidental Petroleum (OXY) downgraded to Neutral from Buy at Mizuho with analyst Timothy Rezvan citing valuation, muted dividend growth, and increasing unit expense trends. 4. AK Steel (AKS) downgraded to Equal Weight from Overweight at Morgan Stanley with analyst Evan Kurtz saying he is concerned about AK's exposure to electrical steel and heavy auto steel, which could prove to be headwinds this year. 5. Williams-Sonoma (WSM) downgraded to Market Perform from Outperform at Telsey Advisory with analyst Cristina Fernandez saying the company is fighting a more competitive environment and softer consumer spending by aggressively increasing promotions to maintain share. The analyst is surprised by the high level of promotions at West Elm and said some real estate contacts have noted softening store sales in December. Fernandez said the turnaround at Pottery Barn could take longer and sees limited margin expansion in 2017. This list is just a portion of The Fly's full analyst coverage.
