Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. JetBlue (JBLU) upgraded to Overweight from Neutral at JPMorgan. 2. First Solar (FSLR) upgraded to Outperform from Market Perform at JMP Securities with analyst Joseph Osha saying he believes that the market is not valuing the company's competitive U.S. position appropriately. 3. Tiffany (TIF) upgraded to Buy from Hold at Deutsche Bank with analyst Francesca DiPasquantonio saying reports this weekend about the interest in Tiffany by LVMH (LVMUY) seem to have a "rational backing" and are tied with its history of interest in the brand. 4. Travelers (TRV) upgraded to Buy from Neutral at MKM Partners with analyst Harry Fong saying while the company missed on Q3 earnings, the discussion at a sell-side event indicated that the miss was driven mainly by the worsening tort environment in commercial auto and general liability. 5. Azul (AZUL) upgraded to Buy from Neutral at Buckingham with analyst Daniel McKenzie saying he expects Azul's multiple to expand as underlying fundamentals become more appreciated.
