The competing activist investor hedge fund Spring Owl released a plan [0] in December with its vision to turn Yahoo! around and achieve a stock price of $113 (currently $35). The basic gist is to focus on Yahoo Finance and Yahoo Sports, kill most everything else, and handle the Alibaba tax situation (ha, as if they haven't already been trying to do that). Things could get really interesting if multiple activists are fighting for board seats over competing visions for the company.
