Stifel analyst Steven Wieczynski said he has a "positive bias" on Norwegian Cruise Line (NCLH) shares ahead of the company's earnings report, citing his belief that the company will deliver a yield-driven Q4 earnings beat and give initial 2019 guidance that meets "relatively benign" expectations. His " only fear" is that Royal Caribbean (RCL) might have set the bar too high with its report and guidance last month. While he expects "probably the cleanest quarter of all the cruise operators" from Norwegian, Wieczynski also questions how much of this may already be in the stock, which is up 24% year-to-date. He keeps a Buy rating and $71 price target on Norwegian Cruise Line shares.
