Abstract: An inventive index includes securities from one or more select companies headquartered in at least two geographic or political localities within a select geographic region. For example, the index can include the ten largest publicly traded corporations by market capitalization within each of the fifty states of the United States of America. The companies within each locality are ranked and the top companies are chosen based on selection criteria. Investment products can be formed based on the inventive index.

Abstract: The invention is directed towards systems and methods for trading a portion of a pool of assets formed from one or more groups of assets. Two or more groups of assets are combined into an asset pool such that the asset pool includes the same assets as the two or more asset groups in similar proportions. The asset pool is then divided into various trading units. Generally, each trading unit can be bought and sold individually or in groups. In some embodiments, the trading unit can be bought and sold via a public exchange such as a stock exchange. In some embodiments, the groups of assets include stock indexes.
