Abstract: Implementing automated stock transactions regarding sports teams may be accomplished by a variety of systems, processes, and techniques. In particular implementations, initial stock values associated with components of sports teams may be determined based on rankings for a plurality of sports teams in a plurality of game-based based statistical categories, each statistical category associated with a component of each team, and each team having a separate ranking in each statistical category. Each team may have a separate stock price for each component. These values may be used to initially assign the stocks to contestants. Additionally, revised stock values may be determined based on the initial assignment of stocks to contestants, and an auction function may allow contestants to exchange stocks. A final stock value for each stock may be determined based on the teams' on-field performance in the statistical categories.
