AN APPARATUS FOR CONSISTENT LINKING OF RATES OF RETURN

摘要

Available accounting, trading, investment performance measurement and analytical systems calculate rate of return for a single period. A system providing consistent linking is composed of data source, consistent linking calculator and storage. It produces rate of return for a total period from rates of return and other integral values of the smaller sub-periods, composing the total period. Such produced rate of return is equal to rate of return calculated for a single total period. Integral characteristics of sub-periods are calculated only once and then are used to produce rate of return for any longer periods that include these sub-periods. System produces time weighted rate of return, approximate and precise money weighted rate of return (internal rate of return). Consistent linking can be done for non-consecutive periods.
