Roth Capital analyst Jeff Martin views the post-earnings selloff today in shares of Insperity as a buying opportunity. The company's Q2 results met expectations and management refined annual guidance ranges, with no change to the midpoint of adjusted EBITDA and adjusted earnings, Martin tells investors in a research note. Insperity tempered the expectation for WSEE growth to a midpoint of 14% from 15%, primarily due to net hiring trends within the client base, he adds. The analyst believes today's 20% selloff on the below consensus Q3 guidance is more as a reflection of the "historically-high" valuation than a lack of market conviction in the investment thesis Martin believes the company's fundamentals are still strong. He lowered his price target for the shares to $138 from $147 and maintains a Buy rating on Insperity.
