Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Canon (CAJ) downgraded to Sell from Neutral at Goldman Sachs with analyst Satoru Ogawa recommending a cautious stance on the Japanese precision equipment sector due to "high valuations and flagging earnings momentum." 2. Integra LifeSciences (IART) downgraded to Neutral from Buy at Citi with analyst Amit Haza saying he sees limited upside following the recent rally in the shares. 3. Nevro (NVRO) downgraded to Equal Weight from Overweight at Morgan Stanley with analyst David Lewis stating that Nevro's commercial message on clinically superiority has not resonated and competitors have gained traction, blunting the company's share gains. 4. Nordstrom (JWN) downgraded to Market Perform from Outperform at Cowen with analyst Oliver Chen citing the stock's current valuation after its recent run, his view of a likely lack of near-term upside to full-line sales and store traffic, and the need for improvements at the Rack division. 5. Las Vegas Sands (LVS) downgraded to Neutral from Buy at BofA/Merrill with analyst Shaun Kelley saying June was the second month of weaker than expected GGR growth, there are continued mixed reads from the firm's Macau Macro Activity Tracker, and weaker FX and trade fears have increased uncertainty.
