Shares of 'Assassin's Creed' maker Ubisoft jumped 33% after a report claimed Tencent and the Guillemot family were planning a potential buyout of the company. Both firms could take Ubisoft private after the video game publisher lost more than half its market value this year, Bloomberg reported. In September, Ubisoft delayed the release of 'Assassin's Creed Shadows' by three months.
