Fly Intel: Today's top analyst calls on Wall Street

Check out today's top analyst calls from around Wall Street, compiled by The Fly. JPMORGAN CUTS ESTIMATES, PRICE TARGET ON FACEBOOK: JPMorgan analyst Doug Anmuth lowered his 2019 and 2020 earnings estimates for Facebook (FB) by 5%-6% on the company's bigger investment increases over the next couple years, which he does not believe are fully captured in consensus estimates. Even with Facebook suggesting it could reach mid-30% operating margins in a few or several years, investments in 2019 could be larger than anticipated in consensus estimates, Anmuth said. The analyst also cut his price target for the shares to $195 from $205. However, he kept an Overweight rating on Facebook. PIVOTAL CUTS DISCOVERY TO SELL: Pivotal Research analyst Brian Wieser downgraded Discovery (DISCA) to Sell with an unchanged price target of $26. Despite "tepid" earnings and "underwhelming" longer-term trends, the stock is up 20% over the past month, Wieser noted. While Discovery's agreements with Hulu and Sling are positive, they do not meaningfully alter the company's fundamentals, the analyst added. His price target implies 19% downside from current share levels. MIZUHO BOOSTS AMD PRICE TARGET: Mizuho analyst Vijay Rakesh raised his price target for AMD (AMD) to $36 from $20 after meeting PC supply chain companies in Asia. AMD's expected server EPYC shipment spike in Q4 will be key, as Intel (INTC) continues to lack a CEO and a competitive technology response to AMD's 12nm Ryzen and 7nm Vega launch, Rakesh said. The analyst, who admits there could be "near-term bumps," kept a Buy rating on shares of AMD. CANACCORD SAYS KAPERNICK AD HAS 'OVERWHELMING' SUPPORT: Canaccord analyst Camilo Lyon conducted a proprietary survey to assess the impact of Nike's (NKE) "Just Do It" ad featuring former NFL quarterback Colin Kapernick. The findings suggest the impact was overall positive and he expects the company to confirm that when it reports Q1 results next week. He believes the ad has had the intended effect of positively skewing the company's brand perception and likely provided a bump in sales. Lyon reiterated his Buy rating and $95 price target on Nike shares. PIPER, WILLIAM BLAIR DEFEND NUTANIX: Nutanix (NTNX) shares dropped 11.5% Monday due to an article from The Information citing a potential competitive hyperconverged infrastructure offering from Google (GOOG, GOOGL), but Piper Jaffray analyst Andrew Nowinski views the selling pressure as "excessive" and reiterates an Overweight rating on Nutanix with a $66 price target. William Blair analyst Jason Ader called the fear of competition from Google "overblown" and reiterated an Outperform rating on Nutanix.
