Abstract: Method and system for management of an investment fund over a specified life, or time horizon Ht, for that fund. Generally, the system includes an investment fund Fn having a fixed time horizon Ht and an associated length to horizon LH. The fund Fn includes several investment assets Ak, which may be contained within investment portfolios Pm, which meet some criteria defining a predetermined asset characteristics. Cash is directed to selected ones of the assets, or portfolios, to establish an investment mix for the investment fund Fn. An important aspect of the method and system is adjustment of the investment mix in accordance with some criteria related to the time horizon Ht, preferably related to the diminishing length to horizon LH, of the investment fund Fn. Thus, as the investment fund matures, the investment mix is changed.

Abstract: An invention for managing assets in one or more investment funds over a specified time. A fund comprises a plurality of assets (e.g., stocks bonds, currencies, gold, silver, oil, gas). A time horizon H.sub.t representing the expected date at which cash will be withdrawn from the fund is associated with each fund. A time L.sub.H represents the length of time remaining between the present time and the horizon time H.sub.t. A risk tolerance, R.sub.I, changes as a function of the decreasing time to horizon L.sub.H. Typically, the risk tolerance decreases as the fund approaches the time horizon H.sub.t (e.g., investments become more conservative toward the end of the life of the fund). A strategic investment mix of assets in the fund is periodically determined as a function of the changing risk, R.sub.I. Investment modifications are accordingly made in the mix of assets in the fund. In one embodiment, a fund also includes a tactical investment strategy component (e.g.
