Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Ambarella (AMBA) upgraded to Overweight at Morgan Stanley by analyst Joseph Moore, who cited the pullback in shares and said business trends have bottomed. Moore added that China surveillance customer checks have been encouraging and other core growth segments such as autos, drones, consumer surveillance cameras, and wearables, ex GoPro, should continue to drive growth. 2. Buffalo Wild Wings (BWLD) upgraded to Outperform at Telsey Advisory on increased confidence in its operating trends, management's plan and its attractive valuation. Following recent management meetings, the firm's analyst has increased confidence in management's plan to elevate and differentiate its B-dubs experience and generate improving operating results. 3. Sensata (ST) upgraded to Buy at SunTrust due to the belief that the company's fundamentals are bottoming just as sentiment towards it is improving. 4. Universal Health (UHS) upgraded to Outperform at Wells Fargo by analyst Gary Lieberman, who believes that volumes at both Universal Health's acute and behavioral operations are likely to be strong in Q1 despite difficult comps and that staffing issues are no longer an issue at the acute care operations and have diminished at its behavioral business. 5. Seacoast Banking (SBCF) upgraded to Outperform at FBR Capital with analyst Bob Ramsey saying activist investor Basswood Capital's material increase in ownership could ultimately result in either a sale or improved performance.
