Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. JetBlue (JBLU) upgraded to Outperform at Cowen due to the belief that April will be the low point for unit revenue. Cowen cites expectations for slower capacity growth in the second half of 2016, an improved balance sheet and upside to the new credit card agreement. 2. National Oilwell (NOV) upgraded two notches to Overweight at Morgan Stanley by analyst Ole Sloreer, who said negative catalysts are played out with the dividend cut and Sete's bankruptcy filing. The analyst said lack of further negative catalysts, a strong balance sheet, and a trough in Q2 make National Oilwell a top contrarian pick. 3. LyondellBasell (LYB) upgraded to Buy at Nomura citing key commodity products of ethylene/polyethylene and key feedstock, ethane, are approaching peak conditions in 2016 as capacity conditions will outstrip demand. 4. Michael Kors (KORS) upgraded to Overweight at Piper Jaffray by analyst Erinn Murphy, who said she now believes the brand is "holding more stable footing on a global scale." She notes Piper's teen survey highlighted Kors as the top handbag brand and that peer Coach (COH) reported solid Q3 results. 5. Stryker (SYK) upgraded to Buy at Sterne Agee CRT with analyst Gregory Chodaczek saying it deserves a premium multiple given best in space fundamentals and near-term levers to expand margins and bolster sales growth. The analyst believes current valuation is too low given its diversified product portfolio and potential of beating his revenue and earnings estimates.
