Citi analyst Jason Bazinet downgraded SeaWorld Entertainment to Sell from Neutral with an unchanged price target of $15 following the stock's recent rally. The stock closed yesterday up 19c to $21.01. Given the high short interest, a short squeeze ensued after SeaWorld beat the Street's Q1 EBITDA expectation by a wide margin, Bazinet tells investors in a research note. Investors, however, are missing three key risks in the form of adverse currency pressure, greater competition and higher interest costs, Bazinet contends. He sees a "poor" risk/reward for SeaWorld shares heading into 2019.
