A financial instrument formed by selecting and weighting securities according to selection and weighting criteria. A primary index may be constructed from a universe of securities meeting at least one selection criterion, and may optionally be weighted according to a selection criterion. Derivative indices may be constructed from the primary index. The derivative indices may be further screened and/or weighted according to the same or different selection criteria. Derivative indices may also be created from other derivative indices, again based on selection and/or weighting criteria. The primary index and any derivative indices may be ranked according to one or more selection criteria, either before or after derivative indices are constructed.
