Grand Canyon Education's 25% correction from the 52 week high creates an "appealing opportunity to revisit one of the highest quality growth stories in the education sector," Piper Jaffray analyst Peter Appert tells investors in a research note. The analyst says accelerating new student start growth, margin upside, and a "solid" earnings beat were the key takeaways from the company's Q4 results. Further, the initial 2019 guidance points to "more of the same," adds Appert. He raised his price target for Grand Canyon to $138 from $135 and maintains an Overweight rating on the name.
