Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. AutoZone (AZO) downgraded to Market Perform from Strong Buy at Raymond James with analyst Dan Wewer citing the company's "poor" third quarter results. 2. Helmerich & Payne (HP) downgraded to Sell from Neutral at Goldman Sachs with analyst Waqar Syed saying the valuation and consensus estimates have downside risk as the U.S. land rig count flattens over the coming months. The analyst expects dayrates to peak around $20,000 per day, which he sees driving consensus estimates lower. Syed cut his price target for Helmerich to $45 from $63. 3. Papa Murphy's (FRSH) downgraded to Market Perform from Outperform at Wells Fargo with analyst Jon Tower citing a slower than expected turnaround in same-store-sales and the potential for increased franchisee unit closures. The analyst lowered his price target for the shares to $5.00 from $5.25. 4. Columbia Sportswear (COLM) downgraded to Buy from Conviction Buy at Goldman Sachs with analyst Lindsay Drucker Mann citing lack of near-term catalysts given the company's cold-weather focused brands. 5. Xilinx (XLNX) downgraded to Market Perform from Outperform at Wells Fargo with analyst David Wong citing valuation with the shares near his unchanged price target of $66.
