Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. General Electric (GE) upgraded to Overweight from Equal Weight at Barclays with analyst Julian Mitchell saying while he does not yet know the magnitude of the 2018 guidance cuts, his talks with investors suggest they are braced for earnings per share of 75c for 2018, free cash flow of 50c, and a dividend cut of 75%-plus. 2. Conagra Brands (CAG) upgraded to Buy from Neutral at UBS with analyst Steven Strycula saying Conagra at current share levels offers the best risk/reward in Food. 3. Willis Towers Watson (WLTW) upgraded to Outperform from Neutral at Credit Suisse with analyst Michael Zaremski saying he has been puzzled by the stock weakness post what was admittedly a confusing Q2 EPS report, because peers have re-rated upwards. 4. CenterPoint Energy (CNP) upgraded to Outperform from Market Perform at Wells Fargo with analyst Sarah Akers saying she is attracted to the company's post-merger outlook, and his sum of the parts valuation supports a 13%-14% total return proposition. 5. Petrobras (PBR) upgraded to Buy from Hold at Santander, to Buy from Neutral at BofA/Merrill, and to Overweight from Neutral at JPMorgan.
