Abstract: A method and a computer system for computing and displaying a phase space relating the performance of a variable to its volatility in an intuitive and interactive way. The method and system enables a comparison of the performances of different stock values and the development of the performance over time. Further, a sub-space of the phase space is determined corresponding to a certain probability threshold of the variables considered.

Abstract: Computer system is provided for securing market profits of financial instrument investors having a mechanism for electronic storing of a yield target for a purchased species of stock or security, a mechanism for electronically acquiring the current rate of the stock or security species, a mechanism for calculating the yield and comparing the calculated yield to the yield target, where the mechanism for calculating and comparing is configured such that, if necessary, they implement one or more recalculations and recomparisons with rates newly acquired by the means for electronically acquiring the current rate until the calculated yield is higher than the yield target. Additional computations and comparisons are done to optimize the invention.
