Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Fluor (FLR) upgraded to Buy from Neutral at BofA/Merrill with analyst Anna Kaminskaya saying she is more constructive on the energy and mining capex cycle, which should recover in the second half of 2018, as firms catch up on under investment over the past few years. 2. T2 Biosystems (TTOO) upgraded to Buy from Neutral at Janney Capital. 3. Adient (ADNT) upgraded to Buy from Neutral at Longbow with analyst Anthony Deem saying he believes shares are de-risked following the cut in 2020 guidance and views risk/reward as attractive given his confidence in the turnaround plan for the SS&M segment. 4. PPL Corp. (PPL) upgraded to Outperform from In Line at Evercore ISI. 5. Arconic (ARNC) upgraded to Buy from Neutral at Longbow with analyst Chris Olin saying the negative reaction to disappointing earnings and guidance, related to short-term headwinds, has created a favorable risk/reward profile, and sees upstream production capacity constraints supporting margin expansion over the next 2-3 years.
