Piper Jaffray analyst Michael Olson raised his price target for TripAdvisor to $58 saying the company last night reported "solid" Q4 results with total revenue and EBITDA ahead of the Street. However, click-based and transaction revenue and Hotel revenue were both below expectations, while non-hotel segment revenue was ahead of consensus and accelerated growth to 38% year-over-year, Olson adds. He views TripAdvisor's 2019 guidance as in-line but notes the company expects headwinds in the first half of the year. The analyst keeps a Neutral rating on the shares.
