Stifel analyst Steven Wieczynski attributes Six Flags' post-earnings selloff to three factors: management comments on its partner in Dubai being in arrears on payments related to its international licensing arrangement; the fact that Q4 visitation decreased 3% year-over-year; and the absence of buyback activity in the quarter. However, he views the selloff as a buying opportunity as he believes 2018 is shaping up to be another strong operating year and has the sense the company remains active in pursuit of additional international licensing agreements. Wieczynski raised his price target on Six Flags shares to $78 from $72 and keeps a Buy rating on the stock.
