Yahoo! (YHOO) shares closed down $1.06, or 2.7%, at $38.32, following the company this morning saying it will sell its “core” advertising business to Verizon Communications (VZ) for $4.83 billion. While much of the deal is as the Street had expected, debate now shifts to how to play the remaining assets — Alibaba Group Holding (BABA), Yahoo! Japan (4689JP), and Yahoo! patent portfolio, and the company’s cash — which will be moved into a separate company that will be publicly traded company dubbed by the Street “RemainCo.” Details of that arrangement weren’t revealed today, and were the subject of numerous questions during a conference call this morning with Marissa Mayer and CFO Ken Goldman. Following that call, several analysts released reports, many of which claim further upside for the shares based on what Alibaba and the rest could be worth: Aaron Kessler, Raymond James: Reiterates an Outperform rating, and a $46 price target.
