Yahoo hasn’t made too many great moves over the course of the past decade, but you can put its decision to spend $1 billion on a 40% stake in Chinese e-commerce firm Alibaba in the win column. In September, Yahoo closed on a deal to sell half its stake back to the firm for $7.6 billion. New CEO Marissa Mayer plans to ship much of the proceeds of the sale back to shareholders in the form of stock buybacks but will keep more than $1 billion on hand in order to finance acquisitions and implement her as-yet-unannounced turnaround plan.
