Description

The present invention relates to a system for calculating a fixed amount of a fixed amount of a financial instrument.

  As a method of trading financial products such as investment trusts, there is a fixed-rate transaction in which an investor (customer) periodically purchases and cancels a fixed amount of financial products. A financial company such as a securities company operates a financial system corresponding to fixed-term fixed-rate transactions so that fixed-rate fixed-rate transactions are executed based on an instruction from an investor (for example, see Patent Document 1).

JP 2006-48187 A

  When an investor makes a fixed-amount purchase (reservation) of an investment trust, the investor needs to specify the brand to be purchased and the purchase price. By the way, general investors form a portfolio including a plurality of investment trusts in consideration of financial risks and the like. The portfolio is composed of the constituents and the ratio of the balance of each constituent to the balance of the entire portfolio. In such a case, if a fixed-price purchase is made, only a specific brand is regularly purchased, so that the portfolio held by the investor may deviate from the desired portfolio. Further, even if all the issues included in the portfolio are purchased at a desired ratio, the price of the investment trust fluctuates every day, so that the portfolio held by the investor may deviate from the desired portfolio.

  Therefore, an object of the present invention is to provide a financial product fixed-term fixed-rate transaction amount calculation system capable of reducing the difference between the portfolio of the financial product of the investor performing the fixed-rate transaction and the desired portfolio of the investor. .

According to the present invention for solving the above-mentioned problems, a financial system for calculating a transaction amount of a financial product of a customer based on portfolio information indicating a ratio of each of a plurality of financial products to the total balance of the plurality of financial products. The product fixed-term fixed-amount transaction amount calculation system includes a holding balance information database storing the number of financial products held by the customer, a target PF information database storing a target portfolio as a target specified by the customer, Based on the base value database in which the base value of the financial instrument is stored, the number of each financial instrument recorded in the held balance information database, and the base value of each financial instrument recorded in the base price database, A first calculation unit for calculating a holding portfolio that is a portfolio of financial instruments held by the customer; A comparison unit that compares the portfolio with a target portfolio stored in the target PF information database for each period specified by the customer; and a plurality of financial products held by the customer based on a comparison result by the comparison unit. A selection unit for selecting a financial instrument whose ratio in the held portfolio is larger than the ratio in the target portfolio; and a total of the cancellation amounts of the financial products selected by the selection unit is a predetermined amount specified by the customer; and And a second calculator for calculating a churn amount of the selected financial instrument such that a difference between the ratio in the held portfolio and the ratio in the target portfolio is reduced for the selected financial instrument. I do.

  According to the present invention, it is possible to reduce a difference between a portfolio of financial products of an investor who conducts fixed-rate transactions and a desired portfolio of the investor.

--- Function blocks realized in the investment trust management system of the first embodiment ---
FIG. 3 is a diagram showing functional blocks and various databases realized in the investment trust management system 10a of the first embodiment. The functional blocks in FIG. 3 are realized in the investment trust management system 10a by the arithmetic device 50 executing a predetermined program. Various databases are stored in the storage device 52.

  The reception unit 100 and the individual order creation unit 101 are realized in the investment trust management system 10a. Further, the investment trust management system 10a includes an investor information DB (database) 200, an order information DB 201, a target PF (Portfolio) information DB 202, a brand information DB 203, a holding balance information DB 204, a business day calendar information DB 205, and an individual An order information DB 206 is included.

  The receiving unit 100 receives various information such as information on investors and information on fixed-rate transactions from investors and management companies. Specifically, the receiving unit 100 receives “investor information”, “order information”, “target PF information”, and “brand information”.

  “Investor information” is information on investors (customers) who conduct investment trust transactions.

  The "order information" is the content of the "fixed-rate transaction" of the investment trust, that is, "purchase or cancellation instruction", "total application amount (purchase or cancellation amount)", "transaction date (transaction frequency or date, etc.)" Information about

  The “target PF information” is information relating to the ratio of each issue determined by each investor based on the investment purpose, the allowable risk, and the like.

  “Issue information” is information on each issue of the investment trust included in the target PF, and includes, for example, the information shown in FIG. The “brand information” indicates a “brand ID” assigned to each brand, a “base price” per unit, a “base price date” indicating a date of the base price, and a number of business days after the application date to execute the contract. “Contract required days” and “Delivery required days” indicating how many business days after the application date will be delivered. In FIG. 4, for example, in “brand A”, “brand ID” is “001”, “base price” is “10,000 yen”, “base price date” is “the current day”, and “contract required days” is “ “The day” and “Days required for delivery” are “4 days”.

  When the “investor information”, “order information”, “target PF information”, and “brand information” are stored in the storage device 52, the investor information DB 200, the order information DB 201, the target PF information DB 202, the brand information Each database in the DB 203 is updated.

  When the designated “transaction date” comes, the individual order creation unit 101 specifies a brand to be purchased or canceled according to the “order information”, and places an order with an investment company that handles the brand.

  The individual order creating unit 101 includes a determining unit 110, a first calculating unit 111, a comparing unit 112, a selecting unit 113, a second calculating unit 114, and an ordering unit 115.

  The determination unit 110 determines whether or not the current date is a “transaction date” in the “order information” by accessing the business day calendar information DB 205 including information indicating a business day of a bank or the like.

  When it is the “transaction date”, the first calculation unit 111 calculates the balance and PF of each issue of the investment trust held by the investor. More specifically, the first calculation unit 111 includes information on the issues held by the investors included in the held balance information DB 204 (for example, information indicating that the issues A have ○ units and the issue B has ○ units), and “brand information”. , And the balance of each issue, PF, is calculated.

  The comparison unit 112 compares the PF (first portfolio) held by the investor calculated by the first calculation unit 111 with the target PF (second portfolio) targeted by the investor on the “transaction date”.

  The selection unit 113 selects a brand to be purchased or canceled based on the comparison result of the comparison unit 112. For example, when the investor has instructed “scheduled fixed amount purchase”, the selection unit 113 selects a brand having a higher target PF ratio than the owned PF ratio. More specifically, the ratio of brand A, brand B, and brand C of the holding PF is 25%, 35%, and 40%, and the ratio of brand A, brand B, and brand C of the target PF is 20% and 30%. , 50%, for example, “brand C” is selected. On the other hand, when the investor has instructed “periodic fixed-rate cancellation”, the selection unit 113 selects a brand having a lower target PF ratio than the holding PF ratio. More specifically, the ratio of brand A, brand B, and brand C of the holding PF is 25%, 35%, and 40%, and the ratio of brand A, brand B, and brand C of the target PF is 20% and 30%. , 50%, for example, “brand A” and “brand B” are selected.

The second calculation unit 114 determines the transaction amount (purchase or cancellation amount) of the issue selected by the selection unit 113 such that the difference between the investor's PF and the target PF is reduced, that is, the retained PF becomes the target PF. Is calculated. For example, the second calculation unit 114 calculates the sum of squares of the difference between each issue included in the holding PF and each issue included in the target PF as “objective function f” (= (name of target A-PF Ａ Brand A) ² + (brand B of target PF-brand B of holding PF) ² + (brand C of target PF-brand C of holding PF) ² ). Then, the second calculator 114 sets the total transaction amount of the selected brands to the amount specified in the “order information” (“total application amount”) and minimizes the “objective function f”. Calculate the transaction amount (purchase amount or cancellation amount) of the selected brand. Here, the “objective function f” indicating the difference between the owned PF and the target PF is the sum of squares of the difference between each issue included in the owned PF and each issue included in the target PF, but is not limited to this. It is not something to be done. For example, the “objective function f” indicating the difference between the owned PF and the target PF may be the sum of the absolute values of the differences between each issue included in the owned PF and each issue included in the target PF. The largest difference (maximum value) among a plurality of differences between each brand included in the holding PF and each brand included in the target PF may be set as the “objective function f”. Then, the second calculation unit 114 executes a general optimization calculation so as to minimize the “objective function f” under the above-described constraint condition that the total transaction amount of the brand is “total application amount”.

  The ordering unit 115 creates “order information” of the issue to be purchased or canceled based on the transaction amount of the issue calculated by the second calculation unit 114, and transmits the “order information” to the management company. The ordering unit 115 stores the “order information” in the storage device 52 and updates the individual order information DB 206.

−−− Regular flat-rate purchase processing −−−
Hereinafter, an example of a process executed by the investment trust management system 10a when the investor X performs “regular fixed amount purchase” will be described with reference to FIG. Note that “investor information” regarding the investor X and “brand information” regarding the brand to be traded are included in each DB in advance. In addition, here, the investor X designates, as the “order information”, for example, “regular fixed-rate purchase” in which 100,000 yen is deposited on the first business day of the second week of each month, and “target PF” As information, it is assumed that the ratios of brands A, B, and C indicate PFs of 20%, 30%, and 50%, respectively.

  First, the receiving unit 100 receives “order information” and “target PF information” relating to the transaction content of the investment trust from the investor X (S100). Then, the receiving unit 100 stores the “order information” and the “target PF information” in the storage device 52, and updates the order information DB 201 and the target PF information DB 202 (S101).

  The determination unit 110 refers to the business day calendar included in the business day calendar information DB 205, and determines whether the current date is the “transaction date” specified in the “order information” (S102). Then, when the current date is the “transaction date” (S102: Yes), the first calculation unit 111 calculates the balance of each issue currently held by the investor X, PF (S103). Specifically, the first calculation unit 111 calculates the “brand information” included in the brand information DB 203 and the information related to the brands A to C held by the investor X included in the held balance information DB 204 (for example, information related to the number of units). ), The balance of each issue held by the investor X and the held PF are calculated. As a result of the calculation, here, for example, since the prices (balances) of the issues A, B, and C are 250,000 yen, 350,000 yen, and 400,000 yen, the ratio of the issues A, B, and C is 25. %, 35%, and 40%.

  Then, the comparing unit 112 compares the PF owned by the investor X with the target PF of the investor X (S104). That is, the comparing unit 112 determines that the held PF (brand A, brand B, brand C) = (25%, 35%, 40%) and the target PF (brand A, brand B, brand C) = ( 20%, 30%, 50%).

  The selection unit 113 selects a brand to be purchased from among the brands A to C included in the target PF to reduce the difference between the owned PF and the target PF (S105). Here, since the ratio (40%) of the brand C of the owned PF is smaller than the ratio (50%) of the brand C of the target PF, the selecting unit 113 selects the brand C as the brand to be purchased.

  The second calculation unit 114 calculates the purchase price of the issue to be purchased so that the "objective function f" is minimized with the "total application amount" (100,000 yen) designated by the investor X (S106). Here, since the second calculating unit 114 purchases only the brand C, the purchase price of the brand C is calculated as 100,000 yen. Thereafter, the ordering unit 115 creates an order so as to purchase 100,000 yen of the brand C, and transmits the order to the financial institution terminal 30 and the management company terminals 40 to 42 (S107). Further, the ordering unit 115 stores the information on the order in the storage device 52 and updates the individual order information DB (S108). After that, the process S102 is performed again.

  In this case, in step S107, the order is transmitted to the financial company and the management company, so that after a predetermined delivery date has elapsed from the order date, the actual balance of the brands A, B, and C held by the investor X is changed. , 250,000 yen, 350,000 yen, and 400,000 yen to 250,000 yen, 350,000 yen, and 500,000 yen. As a result, the PF held by the investor X becomes (23%, 32%, 45%) from (brand A, brand B, brand C) = (25%, 35%, 40%). Therefore, the PF held by the investor X is closer to the target PF (20%, 30%, 50%) than before the issue C is purchased. As described above, in the present embodiment, the investor X can bring the owned PF closer to the desired target PF while forming an asset by “scheduled fixed amount purchase”.

  In the example described above, only the issue C was purchased because the “total amount of application” was a relatively small percentage (10%) of the assets held by the investor. On the other hand, the “total application amount” may occupy a relatively large proportion. In such a case, the second calculation unit 114 performs the optimization calculation so that the purchase amount is “total application amount” and the “objective function f” is minimized, so that all brands A to C are selected. , May be purchased.

−−− Periodical flat-rate cancellation −−−
Hereinafter, an example of a process executed by the investment trust management system 10a when the investor Y performs the “periodical fixed-rate cancellation” will be described with reference to FIG. It is assumed that the “investor information” on the investor Y and the “brand information” on the brand to be traded are included in each DB in advance. In addition, here, the investor Y indicates, as “order information”, for example, “periodical cancellation” in which 100,000 yen is canceled on the first business day of the second week of each month. As information, it is assumed that the ratios of brands D, E, and F indicate PFs at which the ratios are 20%, 30%, and 50%, respectively.

  First, the receiving unit 100 receives “order information” and “target PF information” regarding the transaction content of the investment trust from the investor Y (S200). Then, the receiving unit 100 stores the “order information” and the “target PF information” in the storage device 52, and updates the order information DB 201 and the target PF information DB 202 (S201).

  The determination unit 110 refers to the business day calendar included in the business day calendar information DB 205, and determines whether the current date is the “transaction date” specified in the “order information” (S202). If the current date is the “transaction date” (S202: Yes), the first calculation unit 111 calculates the balance of each issue currently held by the investor Y, PF (S203). Specifically, the first calculation unit 111 calculates the “brand information” included in the brand information DB 203 and the information about the brands DF held by the investor Y included in the held balance information DB 204 (for example, information about the number of units). ), The balance of each issue held by the investor Y and the PF held are calculated. As a result of the calculation, here, for example, the balances of the brands D, E, and F are 200,000, 400,000, and 400,000 yen, so that the ratios of the brands D, E, and F are 20% and 40%, respectively. %, 40%.

  Then, the comparing unit 112 compares the PF held by the investor Y with the target PF of the investor Y (S204). That is, the comparing unit 112 determines that the owned PF (brand D, brand E, brand F) = (20%, 40%, 40%) and the target PF (brand D, brand E, brand F) = ( 20%, 30%, 50%).

  The selecting unit 113 selects a brand to be canceled in order to reduce the difference between the owned PF and the target PF from among the brands D to F included in the target PF (S205). Here, since the ratio (40%) of the brand E of the owned PF is larger than the ratio (30%) of the brand E of the target PF, the selecting unit 113 selects the brand E as the brand to be canceled.

  The second calculation unit 114 calculates the surrender amount of the issue to be surrendered so that the “objective function f” is minimized with the “total application amount” (100,000 yen) specified by the investor Y (S206). Here, since the second calculating unit 114 cancels only the brand E, the cancellation amount of the brand E is calculated as 100,000 yen. Thereafter, the ordering unit 115 creates an order so as to resolve the brand E by 100,000 yen and transmits the order to the financial institution terminal 30 and the management company terminals 40 to 42 (S207). Further, the ordering unit 115 stores information on the order in the storage device 52 and updates the individual order information DB (S208). After that, the process S202 is executed again.

  In this case, in step S207, the order is transmitted to the financial company and the management company, so that after a predetermined delivery date has elapsed from the order date, the actual prices of the brands D, E, and F held by the investor Y are From 200,000, 400,000 and 400,000 yen to 200,000, 300,000 and 400,000 yen. As a result, the PF held by the investor Y is approximately (22%, 33%, 45%) from (brand D, brand E, brand F) = (20%, 40%, 40%). Therefore, the PF held by the investor Y is closer to the target PF (20%, 30%, 50%) than before the issue E is canceled. As described above, in the present embodiment, the investor Y can bring the owned PF close to the desired target PF while performing “fixed-term fixed-rate cancellation” of the asset.

  In the example described above, only the issue E was canceled because the “total application amount” was a relatively small percentage (10%) of the assets held by the investor. On the other hand, the “total application amount” may occupy a relatively large proportion. In such a case, the second calculation unit 114 performs an optimization calculation so that the cancellation amount becomes the “total application amount” and the “objective function f” is minimized, so that all brands D to F are selected. , May be canceled.

--- Function blocks realized in the investment trust management system of the second embodiment ---
FIG. 7 is a diagram showing functional blocks and various databases realized in the investment trust management system 10b of the second embodiment. Although the details will be described later, the investment trust management system 10b is a system for evenly canceling the PF held by the investor, unlike the investment trust management system 10a. The functional blocks in FIG. 7 are realized in the investment trust management system 10b by the arithmetic device 50 executing a predetermined program. Various databases are stored in the storage device 52.

  The reception unit 150 and the individual order creation unit 300 are realized in the investment trust management system 10b. Further, the investment trust management system 10b includes an investor information DB 200, an order information DB 201, a brand information DB 203, a holding balance information DB 204, a business day calendar information DB 205, and an individual order information DB 206. Note that the investment trust management system 10b in which equal termination is executed does not include the target PF information DB 202.

  Further, since the various databases are the same as the respective blocks in the investment trust management system 10a, the detailed description is omitted here.

  The receiving unit 150 receives various information from investors and the management company, such as information on investors and information on fixed-rate transactions (information on equal cancellation). Specifically, the receiving unit 150 receives “investor information”, “order information”, and “brand information”.

  The individual order creating unit 300 includes a determining unit 500, a selecting unit 501, a first calculating unit 502, a second calculating unit 503, and an ordering unit 504.

  The determining unit 500 determines whether or not the current date is a “transaction date” in the “order information” by accessing the business day calendar information DB 205 including information indicating a business day of a bank or the like.

  When the date is “transaction date”, the selecting unit 501 refers to the held balance information DB 204 and specifies and selects each issue of the investment trust held by the investor.

  The first calculation unit 502 calculates the balance and PF of each issue held by the investor. Specifically, the first calculation unit 502 determines the information on the issues held by the investors included in the held balance information DB 204 (for example, information indicating that the issues A have the ○ unit and the issues B has the ○ unit), and “the issue information”. , And the balance of each issue, PF, is calculated.

  The second calculation unit 503 calculates the surrender amount of each brand so that the sum of the “total application amount (cancellation amount)” becomes the amount specified in the “order information” and the PF held by the investor is maintained. For example, when the ratio of the issues G, H, and I of the holding PF is 25%, 35%, and 40%, the second calculation unit 503 determines that the ratio of each issue is the same as before the cancellation. Calculate the surrender value of each issue. In addition, in the case of equal cancellation in which each stock is canceled so as to maintain the ratio of each stock, the second calculation unit 503 multiplies “the total amount of the application” by the ratio of each stock, and the cancellation amount of each stock is calculated. Can be calculated.

  The ordering unit 504 creates “order information” of the issue to be canceled based on the cancellation price of the issue calculated by the second calculation unit 503, and transmits the “order information” to the management company. Further, the ordering unit 504 stores “order information” in the storage device 52 and updates the individual order information DB 206.

------ Periodical flat-rate cancellation (equal cancellation) ---
Hereinafter, an example of a process executed by the investment trust management system 10b when the investor Z performs “scheduled fixed-rate cancellation” will be described with reference to FIG. Note that “investor information” regarding the investor Z and “brand information” regarding the brand to be traded are included in each DB in advance. In addition, here, the investor Z designates, as the “order information”, for example, “periodical flat-rate cancellation” for canceling 100,000 yen on the first business day of the second week of each month, It indicates that the PF will be maintained, that is, the investment trusts it will hold will be evenly terminated.

  First, the receiving unit 150 receives "order information" from the investor Z regarding the transaction contents of the investment trust (S300). Then, the receiving unit 150 stores the “order information” in the storage device 52 and updates the order information DB 201 (S301).

  The determining unit 500 refers to the business day calendar included in the business day calendar information DB 205 and determines whether the current date is the “transaction date” specified in the “order information” (S302). Then, when the current date is “transaction date” (S302: Yes), the selection unit 501 refers to the held balance information DB 204, specifies the brand of the investment trust currently held by the investor Z, and assigns each brand. Select (S303).

  The first calculation unit 502 calculates the balance and PF of each issue currently held by the investor Z (S304). Specifically, the first calculation unit 502 calculates the “brand information” included in the brand information DB 203 and the information (for example, information about the number of units) included in the held balance information DB 204 about the brands GI held by the investor Z. ), The balance of each issue held by the investor Z and the held PF are calculated. As a result of the calculation, here, for example, if the prices of the issues G, H, and I are 250,000 yen, 350,000 yen, and 400,000 yen, the ratio of the issues G, H, and I is 25%, 35 %, 40%.

  The second calculation unit 503 calculates the surrender amount of each issue at the time of equal cancellation with the “total application amount” (100,000 yen) designated by the investor Z (S305). Here, the second calculation unit 503 calculates that the cancellation amounts of the brands G, H, and I are 25,000 yen (100,000 yen × 0.25) and 35,000 yen (100,000 yen × 0.35, respectively). ) 40,000 yen (100,000 yen x 0.4).

  Thereafter, the ordering unit 504 creates an order based on the calculation result so as to cancel each of the brands G to I, and transmits the order to the financial institution terminal 30 and the management company terminals 40 to 42 (S306). Further, the ordering unit 504 stores information on the order in the storage device 52 and updates the individual order information DB (S307). After that, the process S302 is executed again.

  In this case, in step S306, the order is transmitted to the financial company and the management company. Therefore, after a predetermined delivery date has elapsed from the order date, the actual prices of the stocks G, H, and I held by the investor Z become From 250,000 yen, 350,000 yen, and 400,000 yen, it will be 225,000 yen, 315,000 yen, and 360,000 yen. Therefore, the PF held by the investor Z is maintained before and after the cancellation.

−−− Summary −−−
The investment trust management systems 10a and 10b of the present embodiment have been described above. The investment trust management system 10a selects a brand to be purchased in order to reduce the difference between the owned PF and the target PF, and calculates the purchase price, based on the instruction of the investor who makes the “periodical fixed-rate purchase”. For this reason, the investor can form an asset while keeping the owned PF close to the target PF. With the importance of self-help asset formation being emphasized, from savings to investment, funding is the main means. This system enables diversified investment based on the ratio of the target PF to be automatically carried out by accumulation.

  Further, the investment trust management system 10a selects a brand to be canceled in order to reduce the difference between the owned PF and the target PF, and calculates the amount of the cancellation based on an instruction of the investor who performs the “fixed-term fixed-rate cancellation”. For this reason, the investor can cash the assets while bringing the owned PF close to the target PF. The number of generations who have retired and have no regular income, and operate while reversing, is increasing. Provide such investors with a means of diversified investment based on the target PF ratio while canceling.

  In addition, the investment trust management system 10b can perform equal termination as "periodic fixed-rate termination" based on an instruction from the investor. This allows the investor to periodically cash out the assets held while equally canceling the stocks held.

  In the first embodiment, in order to set the retained PF as the target PF, the price of the brand to be purchased or canceled is obtained by optimization calculation. For this reason, in the first embodiment, it is possible to accurately bring the owned PF closer to the investor's desired target PF.

  In general, when a financing company such as a securities company selects an investment trust brand to be purchased or canceled, the investor interacts with the financing company based on the investment management business stipulated in the Financial Instruments and Exchange Act. It is necessary to sign a discretionary investment agreement. In such cases, the investor generally has to pay an investment advisor fee to the financier. When operated based on the "discretionary investment agreement", there are cases where accounts with tax benefits (such as NISA accounts) cannot be used. In addition, some investors avoid the complexity of concluding contracts based on the investment management industry. In the investment management industry, contracts are generally complicated because investors delegate the authority to make investment decisions and investments to financiers. On the other hand, in the present embodiment, the financing company receives an instruction of the target PF from the investor, together with the content of the “fixed-term fixed-rate transaction”. For this reason, the name and the amount of the investment trust to be purchased or canceled by the financier are automatically determined based on the instruction from the investor regarding the “fixed-term fixed-rate transaction” and the target PF. This eliminates the need for the investor to enter into a discretionary investment contract with the financier, and can achieve the same effect with a contract or consent within the scope of the first-class financial instruments business required for the sale of investment trusts. (*). Therefore, the investor can make the PF of the investment trust owned by the investor close to the target PF while suppressing the cost (investment advisory fee) to be paid to the financier. Contracts between investors and financiers are also less complex than discretionary investment contracts.

* (Citation of the law)
Cabinet Office Ordinance on Financial Instruments Business, etc. Article 117, paragraph 21 (Prohibited acts)
With regard to the sale and purchase of securities or derivative transactions or their consignment, etc., after obtaining the consent of the total amount of funds from the customer, the classification, brand, number, and price (for derivative transactions, the corresponding items) Among them, those for which consent cannot be obtained are determined by processing by a computer or other processing according to a predetermined method when certain facts occur, and financial instruments business operators etc. execute transactions according to these Act of concluding a contract with the following contents in writing (excluding contracts concluded by a method that uses an electronic information processing organization or other methods that use information and communication technology.)
The act of bringing the owned PF closer to the target PF is generally called “rebalancing”. In the "rebalance", a brand whose ratio of the target PF is lower than the ratio of the owned PF is canceled (sold), and a brand whose ratio is increased by the cancellation price is purchased. Canceling a financial instrument held by an investor will result in a tax on the profits generated at the time of the cancellation. In the present embodiment in which “regular fixed-rate purchase” is performed, it is possible to bring the PF held by the investor closer to the target PF without canceling a financial product such as an investment trust. Therefore, the investor can bring the owned PF closer to the target without generating tax. Further, since the investor can make a fixed-amount purchase of the investment trust in consideration of the target PF, it is also preferable as a transaction for a defined contribution pension plan that forms an asset only by the purchase. If the same thing is to be realized with a defined contribution pension, the investor needs to calculate the ratio and amount on his / her own in order to perform the "switching" of canceling and purchasing with the surrender value. However, there are investment trusts and time deposits that do not support “switching,” and it is troublesome for investors to specify them each time.

  It should be noted that the above embodiments are for the purpose of facilitating the understanding of the present invention, and are not for limiting and interpreting the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention also includes equivalents thereof.

  In the present embodiment, when the investor has instructed “scheduled fixed-price purchase”, the selection unit 113 selects a stock with a lower target PF ratio than the owned PF ratio, When "fixed-rate cancellation" is instructed, a brand having a higher target PF ratio than the ratio of owned PFs is selected, but the present invention is not limited to this. Specifically, the selection unit 113 may select all of the issues included in the investor's target PF. Even in such a case, the second calculation unit 114 executes a general optimization calculation to minimize the “objective function f”, so that the “purchase amount” and the “cancellation amount” are appropriate. Is calculated.

  Further, for example, in the present embodiment, the case where the investment trust is held as the financial product held by the investor has been described, but the financial product held by the investor is not limited to the investment trust. Specifically, in the present embodiment, any financial product that can be ordered (traded) with a designated amount may be used, such as stocks, bonds, cash (including foreign currency), gold, and overseas ETFs (Exchange Traded Funds: listed). Investment trust). Even when an investor creates a PF that combines these financial products, the investor can bring the owned PF closer to the target PF by purchasing and canceling each product at a fixed rate.
