Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Carnival (CCL) downgraded to Underweight from Equal Weight at Morgan Stanley by analyst Jamie Rollo after the firm's checks indicated cruise demand weakened and prices were soft in August. The analyst lowered Carnival's price target to $48 from $54. 2. lululemon (LULU) downgraded to Equal Weight from Overweight by Morgan Stanley analyst Kimberly Greenberger following the company's earnings report. She noted that the company's comps are decelerating and that traffic remains a headwind. Given the slowdown seen in Q2, Greenberger lowered her comp assumptions and cut her price target on lululemon shares to $70 from $74. 3. Morgan Stanley analyst Meta Marshall downgraded Ciena (CIEN) to Equal Weight from Overweight, saying that while the company can likely outgrow the market over the next couple of years, its industry remains intensely competitive and growth is slowing in the long haul market, leaving little room for multiple expansion. Marshall maintains a $23 price target on Ciena shares. 4. Smith & Wesson (SWHC) downgraded to Hold from Buy at Craig-Hallum by analyst Steven Dyer, as he thinks the current environment is "as good as it gets" for firearms demand. Based on past cycles, Dyer contends that November's election and activity right after that will likely mark the top of the current firearms cycle and the stock will react as comps become more difficult. 5. STMicroelectronics (STM) downgraded to Underperform from Neutral at BofA/Merrill, with the firm saying structural pressures will drive declining revenue from Q3 of 2017 and beyond.
