Background of the Invention
[0003] The present invention relates generally to the field of business systems, and specifically relates to the field of investment fund management systems.
[0004] Long-term investment plans, such as pension plans, enable an investor to save for retirement. Pension plans typically are divided into two types: defined benefit plans; and defined contribution plans. A defined benefit plan involves a promise made by an employer of a lifetime definite benefit paid to the recipient after retirement. The employer funds the promise by investing in trust for the recipient. In a defined contribution plan, the employer and/or the employees contribute a definite amount of money to an investment plan. The benefit paid after retirement is uncertain; it is determined by the performance of the investment plan. 401K plans are an example of defined contribution plans.
[0005] In a typical defined contribution plan, the employer establishes a group of investment funds of specified characteristics, from which the employee may select. The group of funds typically is diverse, including funds specializing in bonds, stocks, money markets, and other asset classes, or combinations of asset classes. These funds may be collective investment funds or mutual funds, managed by the employer or by a third party.
[0006] An employee typically invests in a fund having characteristics matching his or her investment preferences, such as high-risk/high expected return or low-risk/low expected return. Over time, as the employee's investment preferences change, that employee may move his or her investment from one fund to another to reflect a change in preferences. But because the typical employee generally is not a trained investment expert, it is possible that sub-optimal selections may be made from among the funds, and that the selections are not optimally revised over time.
[0007] Many employees in defined contribution plans do not appreciate that investments with high-risk and high expected return—such as equity securities—may be appropriate even for risk averse investors if their time horizons are sufficiently far in the future, and if the investment is properly diversified. Thus, many employees tend to invest more conservatively than an investment expert would do under like circumstances. Because conservative investments generally have low returns over the long term, an unnecessarily risk-averse strategy may be expected to produce disappointing long-term performance.
[0008] Many employees in defined contribution plans do not possess sufficient expertise to select investment funds to match their risk preferences, even when their risk preferences are appropriate. As a result, investments may be selected that either expose an employee to unexpected risks, or expose the employee to unexpectedly low returns.
[0009] Finally, many employees in defined contribution plans do not possess sufficient expertise, or wish to devote sufficient time and attention, to appropriately revise their selection of funds as market conditions change, and as their own life circumstances change. If an employee neglects to revise his or her investments, or revises them inappropriately—perhaps due to emotions of fear or greed—that employee will be exposed to unexpected and inappropriate risks when market conditions change, or when his or her own life circumstances change.
[0010] The typical employee generally is unwilling to pay the costs to obtain private professional investment advice, or may be unaware that it is available. The typical employer generally is unwilling to provide advice to employees, either due to a lack of sufficient expertise, or due to an unwillingness to bear potential legal liabilities. Thus, there remains a need for a system and method for a typical employee in a defined contribution plan to make appropriate investments, to reflect appropriate long-term trade-offs of risk and return, to select investments that accurately reflect those trade-offs, and to revise those investments through time in response to changing market conditions and the employee's changing preferences.
Summary of the Invention
[0011] The present invention relates to a method and system for managing one or more investment funds over a specified life of that fund. The data processing method of the present invention involves determining a time horizon Htassociated with each investment fund Fn. The time horizon Htdefines the expected date at which cash may need to be withdrawn from the fund and has an associated parameter LHrepresentative of the length of time remaining between the present and the time horizon Ht. A plurality of investment assets are stored, together with information regarding each asset. These assets may be maintained within portfolios, each portfolio having a predetermined characteristic, thus the compilation of associated assets may reflect or establish the portfolio characteristic.
[0012] Cash initially is directed to selected ones of the assets or portfolios, to establish an investment mix. The investment mix is adjusted at periodic intervals in accordance with some criteria that is related to the diminishing length to time horizon LH. The criteria may include a change in risk tolerance RI, as a function of the remaining length to time horizon LH, associated with each fund. Typically, the RIvalue decreases as the fund approaches the time horizon Ht. The criteria may include other processes or rates that are keyed to the time horizon of the fund.
[0013] The assets or portfolios included in each investment fund may be correlated to the fund based on factors in addition to LHand Ht, such as initial risk tolerance RI, and/or some predetermined investment criteria LI. The predetermined investment criteria LImay include such criteria as invest only in equity securities, diversify across a minimum number of asset classes, invest a percentage in money market instruments, and the like. In addition, individual portfolio characteristics may be based on several criteria, including expected volatility of the investment assets, expected responsiveness of the investment assets to market conditions, and expected return on the investment assets.
[0014] The present invention also is directed to a data processing system that corresponds to and performs the above described method. The invention is described in further detail in the following drawings and detailed description.

Detailed Description of the Preferred Embodiment
[0021] The present invention is a system and method for managing investment funds wherein each fund has a fixed time horizon Htand a diminishing length to horizon LH. That is, the fund is managed by manipulating the investment mix of the fund in accordance with some criteria related to the diminishing length to horizon LHof the fund.
[0022] Generally, the method includes establishing an investment fund Fnwith a fixed time horizon Htand a diminishing length to horizon LH. A relationship is established between at least one investment asset and the fund in accordance with a first set of criteria. One or more investment assets may be contained in a portfolio, which portfolio may be in some relationship with the fund. Cash may be directed to selected ones of the assets or portfolios to establish an investment mix for the investment fund. An important aspect of the invention is adjustment of the investment mix in accordance with some criteria related to the diminishing length to horizon LHof the investment fund Fn. Thus, as the investment fund matures, the investment mix is changed within the fund.
[0023] One exemplary manner in which the investment mix may change over the life of the fund is to change the distribution of new cash across the portfolios as such cash is invested in the fund or otherwise becomes available. Another manner is to change the asset or portfolio mix by exchanging assets or portfolios having one type of characteristic for assets or portfolios having a different type of characteristic. Typically, the investment strategy of an investment fund will become more conservative as it approaches maturity and the distribution of cash among the assets or the mix of portfolios reflects that change in the fund.
[0024] FIG. 1 graphically depicts an exemplary investment fund structure embodying the present invention. As shown, a plurality of investment funds Fnare made available to individual investors. Each fund has an associated time horizon Ht, which indicates the date that the individual investor anticipates receiving money from the fund. The time horizon Htpreferably is expressed in terms of a specific calendar date for maturity. Also associated with each fund Fnis a length to horizon LHwhich represents the remaining time between the present and the time horizon Ht.
[0025] In an alternative embodiment, each fund Fnalso may have an associated risk tolerance value RI, representative of whether the individual investor generally has a conservative or aggressive investment strategy. In another embodiment, an individual investor may impose other constraints for a particular fund, such as designation of allowable investments. For example, an investor may designate that the fund should consist only of domestic investments, or the fund should contain a predominant portion of portfolios directed to a specified technology or industry. In this manner, some funds of a specific time horizon Htmay be established which are tailored in accordance with investor-specified attributes.
[0026] A relationship may be established between one or more investment portfolios Pmand each investment fund Fn. The portfolio Pmhas an associated portfolio characteristic, or parameter, that may be predetermined either by the fund manager or by the individual investor. The portfolio characteristic typically is determined by or defines the type of assets constituting the portfolio. These assets may be characterized by such factors as the expected volatility of the investments, the expected responsiveness to market conditions, and expected return on the investments. Thus, an investment fund Fnhaving a particular time horizon Httypically consists of several portfolios, each portfolio having a different characteristic. Alternatively, a relationship is established between one or more investment asset Ak, without the use of a portfolio. In that embodiment, each investment asset Akis handled in a manner similar to a portfolio Pm.
[0027] The portfolios Pmof FIG. 1 may each consist of one or more investment asset Ak, or an asset mix, each representing a major asset class. These assets may include securities, such as stocks, bonds, and the like and may be combined in a manner that achieves the predetermined portfolio characteristic.
[0028] In one embodiment, and as shown in FIG. 2, each fund Fnmay include a portion known as present value of future cash flow Pvf. This portion represents a “phantom asset”, or the total value of all future cash flows that are expected to be received for the fund Fn. In that illustrated embodiment, the fund Fnhas a current balance CBrepresentative of the current value of the portfolios (P1-P5), including any cash available for investing. Available cash is removed from the Pvfas it becomes available for investing in the portfolios of the particular fund Fn.
[0029] An important aspect of the present invention is maintaining a total fund balance, including Pvfand CB, of a particular fund, while changing the investment mix of that fund over the time horizon for that fund. One way in which the present system may administer the investment funds, each fund having a fixed time horizon, is to adjust the investment mix in accordance with some identified criteria.
[0030] In one embodiment of the invention, and as depicted in FIG. 2, the investment mix is adjusted by adjusting the percentage of available cash distributed among the portfolios Pmin each fund Fn. As shown, cash initially is invested in the portfolios P1-P5in accordance with a certain percentage. In the illustrated embodiment, P1has a relatively high-risk characteristic, whereas P5has a relatively low-risk characteristic. While the fund is young, i.e., the Pvf(60%) is greater than the cash balance CB(40%), the individual portfolios have a greater relative percentage of cash invested in the higher-risk portfolios P1and P2. Over the maturity of the fund, the cash is distributed among the portfolios such that near the time horizon for the fund, the portfolios have a greater relative percentage of value invested in the lower-risk portfolios P4and P5.
[0031] In a preferred embodiment, the change in distribution of available cash may be a function of not only length to horizon LHbut also of risk tolerance RI, as previously described, associated with the particular fund. Other processes that consider the time horizon of the fund may be used in conjunction with the present system.
[0032] In another embodiment, the portfolio mix or asset mix for a given fund is adjusted as a function of the length to horizon LHby exchanging individual ones of the portfolios Pmor investment assets Akfor portfolios or investment assets having different characteristics. Typically the exchange is between portfolios or assets having higher-risk characteristics for ones having lower-risk characteristics. As with the illustrated embodiment of FIG. 2, these changes may be made as some function of the time horizon and risk tolerance RI, depending on the particular system.
[0033] The hardware environment of the present system is depicted generally in FIG. 3. As shown, the system 410 includes an input device 400, such as a keyboard, in communication with a computer 402, including a processor 404 and at least one memory device 406. The elements of the present system 410 may be embodied in one or more processors 404, one or more devices that constitute the processor 404, or any other standard hardware devices commercially available. The system 410 also may include a display device 408 for generating a display of one or more of the outputs of the present system.
[0034] FIG. 4 depicts a flow chart of one embodiment of the present system. In the illustrated system, the storage medium 406 is initialized 500 by the processor 404 or by some other device in the computer 402. One or more investment funds Fnare established 502 by the processor 404 and stored 504 in the storage medium 406. A time horizon Htand a length to horizon LHare associated 506 with each of the stored investment funds Fn, and the data FnHtLHis stored 510 in the storage medium 406. At the same time, or at a separate time, one or more investment asset Akmay be established 512 and stored 514 on the storage medium. Alternatively, step 512 may include establishing a portfolio Pmhaving one or more assets Ak.
[0035] The processor 402 establishes 516 a correlation between the stored FnHtLHdata and the stored Akor Pmdata, and that correlated data is stored 518 in the storage medium. The processor 402 directs 520 available cash funds to the investment assets Akor portfolios Pmassociated with each fund Fnand according to the length to horizon LHassociated with each fund Fn, as described in detail above. The initial distribution 520 of cash among the investment assets Akor portfolios Pmestablishes the investment mix of each fund Fn. It is this investment mix that is adjusted 522 in accordance with some predetermined criteria, as described in further detail below, which criteria also is a function of the length to horizon LHassociated with the fund Fn.
[0036] In one embodiment of the present invention, as described above, the system 410 includes a single storage medium 406 that is used to store the output of each of the elements of the system. In alternative embodiments, the system 410 may include a plurality of storage media, each of which may be used to store the output generated by different ones of the elements. Thus, reference to a storage medium includes the same or different storage media for purposes of the present invention.
[0037] In a preferred embodiment, the criteria by which the investment mix is adjusted 522 is a rate of risk tolerance RIthat is related to the investment fund Fnas a function of the length to horizon LHassociated with that fund Fn.
[0038] There may be a correlation between the expected risk of an investment and the expected return on investment. By associating the time horizon Htwith a risk indicator, such as RI, it may be possible to decrease the amount of risk in investments over the life of a particular fund. For example, a fund F1that has an Htof 40 years may have an initial investment mix that has high expected risk because the investor has high risk tolerance RI. Conversely, a fund F2 may have an associated Htof 10, in which the RIis quite low, leading to conservative investment mix.
[0039] In practicing a preferred embodiment of the present invention, and as shown in FIGS. 5A-5D, once a fund Fnis established, the risk tolerance RIshifts over time for that fund, without transferring any cash out of the fund. The illustrated fund Fnhas a time horizon Htof 40 years. In the first year, FIG. 5A, the RIis high, thus the investment mix will reflect the aggressive investment approach. Over time, as LHdiminishes, the RIshifts and the fund becomes more risk averse, as illustrated in FIG. 5B. Over time, the RIfor the fund Fndecreases until a more conservative, or less aggressive, investment mix is achieved, as illustrated in FIGS. 5C and 5D. The RIremains fixed, i.e., conservative or aggressive, but the level shifts over the diminishing length to horizon LH.
[0040] FIG. 6 depicts a general flow chart of a preferred embodiment of practicing the adjusting step 522 of the present invention. In the illustrated embodiment, information is obtained 700 from an individual investor regarding investor portfolio information and market data 800 is obtained regarding the market. The step of obtaining 700 investor portfolio information includes establishing a current portfolio 702, which becomes the repository for assets and cash. Investor assumption data may also be obtained 704.
[0041] The step of obtaining 700 investor portfolio information also includes obtaining 706 risk tolerance data. Such data includes both the investor policy risk tolerance, which typically is a measure of an aggressive/conservative investment policy on behalf of the investor, and a market response coefficient, which typically is a measure of whether the investor is generally contrary, market neutral, or insurance oriented. An investor risk tolerance RIis determined 708, which may be used in determining 812 portfolio risk, described in further detail below.
[0042] Finally, the step of obtaining 700 investor portfolio information may include obtaining 710 contribution data. That data may include such factors as the investor's current salary, expected growth rate of that salary, the investor's contribution rate, any matching funds contributed by a third source, the investment horizon Ht, plus any outstanding or current fund balance. Other factors may be included or omitted as appropriate for an individual investor or system. Each of these factors may be used, in combination or individually, to calculate 712 the anticipated cash flow stream for the investor.
[0043] The step of obtaining 800 market data preferably includes the steps of obtaining 802 interest rate data and obtaining 804 other market data. The step of obtaining 802 interest rate data may include calculating 806 some discount function that then may be used, in combination with the anticipated cash flow stream produced in step 712, to determine 808 the present value of future cash flow Pvf, in the form of future cash flows.
[0044] The step of obtaining 804 other market data may include determining market risk premiums, expected returns, and transaction costs associated with buying/selling portfolios and/or individual assets, which may include obtaining alphas for each portfolio and/or each asset. An alpha is defined as the difference between the investor's expected return and the observed market consensus expected return for any particular portfolio or asset. Other values may be obtained 804 as appropriate for the particular system and investors. The market data may be used to forecast 810 market risks and returns, and to determine 812 the portfolio risk.
[0045] The fund then is optimized 900 in accordance with any commercially available optimizer program or system, such as AAT, available from Scientific Press (So. San Francisco, Calif.). Inputs to an optimizer program 900 typically include a lower bound, which may be set to be that portion of the portfolio which represents the present value of all future contributions to the portfolio by the investor, or set in accordance with the investors' desired minimal exposure to an asset class or portfolio. Optimizers 900 typically also include an upper bound, which represents a maximum exposure that any investor wishes to have to one or more asset classes or portfolios. Other inputs of available optimizers typically include: asset and/or portfolio characteristics, such as expected returns, risks, and correlations; transactions costs of all types; current holdings; and investor risk tolerance. Other parameters may be considered or omitted, depending upon the particular optimizer used in conjunction with the present invention.
[0046] The present system may further include creating 902 an investor trade list. The trade list may be in the form of output from the optimizer 900, and lists the assets that need to be exchanged to obtain an optimal mix of investments. The investor portfolio may then be rebalanced 904, then maintained 906 for a specified period, such as for one month. Typically, trade lists are a necessary part of the process even when trading activity is motivated by contributions or withdrawals of cash.
[0047] While one particular embodiment of the invention has been described in detail, it will be understood that the invention may be implemented through alternative embodiments. Thus, the scope of the invention is not intended to be limited to the embodiments described above, but is to be defined by the appended claims.
