Deutsche Bank analyst Chris Woronka views the recent share weakness in Vail Resorts as unwarranted. Recent conversations with "negatively-positioned" investors suggest there is a view that the "Ikon" pass launched last week by privately-held Alterra Mountain Company will ignite a "pass war" between the two companies, Woronka tells investors in a research note. The analyst "strongly" disagrees with that view. The Ikon pass will get casual skiers more focused on the benefits of a pass product, and ultimately spur incremental pass sales on an industry-wide basis, Woronka argues. He increased his estimates for Vail to reflect tax reform and keeps a Buy rating on the stock with a $265 price target.
