  • Publication number: 20130290219
    Abstract: Embodiments are described for a system and method for comparing risk associated with a financial asset by creating a risk-return profile for the first asset and a risk profile for the second asset over a defined time period having a plurality of asset holding times, calculating an average negative total return of each of the first and second assets for each of the plurality of asset holding times, calculating a worst case total return of each of the first and second assets for each of the plurality of asset holding times, and calculating a percentile total return each of the first and second assets for each of the plurality of asset holding times.

  • Patent number: 8548888
    Abstract: A method and apparatus for displaying a financial asset risk-return profile is disclosed. The method includes determining the length of a period; computing an integer number of intervals in a date range set, an interval being an integer multiple of the length of the period; for each interval, computing the number of interval sub-sets in the date range set, each interval sub-set spanning the time spanned by a corresponding interval; for each interval, computing a metric of the interval sub-sets; and for each interval, displaying the computed metric. The displayed financial asset risk-return profile includes a total return component and a hold time component of risk.

  • Patent number: 8433635
    Abstract: A method and apparatus for optimizing a portfolio of financial assets is disclosed. The method includes computing a risk-return profile for each of a plurality of feasible weight distributions of financial assets in the portfolio and selecting as the optimal distribution the risk-return profile having the greatest annualized total return. Also disclosed is a method for providing a real-time design of a portfolio of financial assets.

  • Publication number: 20060091356
    Abstract: Calcium hypochlorite compositions that are classified as a Packing Group III Division 5.1 oxidizer material or as a non-Division 5.1 oxidizer material are described. In one embodiment, the compositions comprise an admixture of particulate calcium hypochlorite and particulate metaboric acid. The calcium hypochlorite is present in the composition in an amount and is of a concentration such that the composition would be classified as a Packing Group II Division 5.1 oxidizer in the absence of said particulate metaboric acid. Other embodiments described are solid shaped articles, e.g., tablets, comprising the described calcium hypochlorite-metaboric acid composition.
