Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Wells Fargo (WFC) upgraded to Outperform from Neutral at Credit Suisse with analyst Susan Roth Katzke saying the company with its Q4 results offered both targets and disclosure to increase clarity on the path to improved returns. 2. Salesforce (CRM) upgraded to Hold from Sell at Loop Capital with analyst Yun Kim saying the company's FY22 estimates of 17% organic revenue growth estimates vs. its previous 20% growth target have been "de-risked", and the recent checks suggest a "modest rebound" in its core business driven by increasing mid-sized deal activity. 3. Schlumberger (SLB) upgraded to Buy from Neutral at BofA with analyst Chase Mulvehill pointing to the rotation away from North American and into international energy names due to the growing uncertainty around the future of U.S. Oil and Gas regulatory environment under the Biden administration. 4. Regeneron (REGN) upgraded to Outperform from Market Perform at BMO Capital with analyst Matthew Luchini saying the company is "well positioned" heading into 2021 with potential for continued strong performance from Eylea, Dupixent and Libtayo and the ongoing Dupixent label expansion efforts and a combination-focused oncology pipeline providing additional growth opportunities. 5. ArcelorMittal (MT) upgraded to Overweight from Neutral at JPMorgan with analyst Luke Nelson saying the outlook for global steel equities has "markedly improved" after a "shaky" first half 2020 and "alpha can still be generated with stock selection" within the steel sector, Nelson tells investors in a research note.
