Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Facebook (FB) upgraded to Buy from Neutral at BTIG with analyst Richard Greenfield saying the secular trends toward mobile devices along with the accelerating shift of ad dollars "are simply too strong to ignore." The analyst highlights the "unexpected strength" of Instagram Stories as well as improvements to Facebook's video strategy. Greenfield says not having a Buy rating on Facebook in 2017 was a mistake that he's not going to allow to continue. 2. Freeport McMoRan (FCX) upgraded to Hold from Sell at Deutsche Bank with analyst Chris Terry citing a more positive Industrials commodity view. He raised his price target for Freeport shares to $14 from $12.50. 3. Wynn Resorts (WYNN) upgraded to Buy from Hold at Aegis with analyst David Bain saying Wynn Macau casinos posses peer-high leverage to VIP and and high-end premium mass segmentation which is leading a still early stage Macau recovery. 4. Motorola Solutions (MSI) upgraded to Buy from Hold at Jefferies with analyst George Notter saying consensus expectations are too low while risks to the LMR franchise increasingly look like a "red herring." After spending time with management, Notter upped his price target for the shares to $100 from $75. 5. Carnival (CCL) upgraded to Outperform from Market Perform at William Blair with analyst Sharon Zackfia saying the company is well positioned to exceed expectations with earnings growth likely to accelerate into fiscal 2018.
