Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Workday (WDAY) upgraded to Overweight from Neutral at Piper Jaffray by analyst Alex Zukin, who said his channel checks indicate the company's fundamentals have improved materially since last quarter. He notes that his checks on Workday and Salesforce (CRM) "came back the strongest in recent memory." 2. Tempur Sealy (TPX) upgraded to Outperform from Market Perform at Raymond James, as analyst Budd Bugatch said all the bad news is known and the improvement in revenues and earnings will become more visible as 2017 unfolds. 3. Capital One (COF) upgraded to Buy from Neutral at Goldman Sachs by analyst Ryan Nash, who raised his price target for the shares to $110 from $106. Almost all of the bank's increases in losses during 2016 can be explained by "growth math," which should have a "finite life to it," Nash tells investors. 4. Credit Suisse (CS) upgraded to Overweight from Equal Weight at Morgan Stanley by analyst Magdalena Stoklosa, who thinks connectivity across businesses, capital utilization, and earnings quality from here will result in more predictable earnings. 5. Chemours (CC) upgraded to Positive at Susquehanna by analyst Don Carson, who sees significant upside he sees to management's modest EBITDA guidance due to greater momentum in TiO2 prices.
