Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. SodaStream (SODA) downgraded to Neutral from Buy at Roth Capital with analyst Anton Brenner noting the company reported "strong" sales and income improvement in the second quarter exceeded estimates. However, he points out that much of the revenue gain apparently was sell-in to distributors and retailers, and retail sales remain soft in important markets. 2. J.C. Penney (JCP) downgraded to Negative from Mixed at OTR Global. 3. Trex Company (TREX) downgraded to Neutral from Outperform at Wedbush and to Neutral from Buy at CL King. 4. Western Digital (WDC) downgraded to Sell from Neutral at Goldman with analyst Mark Delaney saying he sees NAND risk from 2017 oversupply, downside potential from the Samsung (SSNLF) royalty and 3D NAND yields, and Chinese companies are attempting to enter the NAND market. 5. Emerson (EMR) downgraded to Sell from Underperform at CLSA with analyst Grace Lee saying Emerson's earnings and guidance disappointed again on renewed weakness in energy markets and industrial spending.
