Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Apple (AAPL) downgraded to Neutral from Buy at Mizuho with analyst Abhey Lamba saying "Enthusiasm" around the upcoming iPhone launch is fully priced in after the stock's year-to-date outperformance. 2. Adobe (ADBE) downgraded to Sell from Hold at Pivotal Research with analyst Brian Wieser citing valuation. 3. Pandora (P) downgraded to Perform from Outperform at Oppenheimer with analyst Jason Helfstein citing a "failure" of his takeout thesis. The capital investment from SiriusXM (SIRI) and Ticketfly will allow Pandora to refocus on its core advertising business, which is the correct strategy, Helfstein tells investors in a research note. He sees share upside to "only" $9.50-$11.00 and removed his $14 price target on the stock. 4. Vantiv (VNTV) downgraded to Sector Weight from Overweight at Pacific Crest with analyst Josh Beck saying "continued retail challenges" could limit fundamental upside. 5. Sanderson Farms (SAFM) downgraded to Sector Weight from Overweight at KeyBanc with analyst Brett Andress citing valuation. This list is just a portion of The Fly's full analyst coverage.
