Stock holding is a subcategory of Commodity Speculation, in which instead of purchasing or selling an entire commodity, players purchase and sell (or hold) a share in a given company, commodity or nation.

Notable examples include Acquire, where players can purchase shares of companies, and benefit if those companies grow before being bought out, and Imperial, where players are purchasing bonds in European nations which grant not only a dividend and points at the end of the game but also the right to control that nation's actions for as long as you are the majority bondholder.
