Description

[Technical field]

[0001] The present invention relates to a program, an information processing device, and an information processing method. [Background technology]

[0002] Applications for managing stocks and placing orders have been developed. For example, Patent Document 1 and Patent Document 2 disclose a system in which the system determines an ideal target portfolio (stock names and their composition ratios) based on the investment type, and rebalances the composition ratios to approach the target portfolio. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-268557 A [Patent Document 2] JP 2018-036928 A [Patent Document 3] International Publication No. 2016136277 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional technology, users cannot individually select stocks and their composition ratios, and it is difficult for users to arbitrarily adjust the stocks and composition ratios they want to hold, and it is also difficult for users to do so at the timing they want. Patent Document 3 also discloses a function for adjusting stocks held by users for buying and selling on a pie chart. However, in Patent Document 3, since a single buying and selling order is placed by manipulating the target stock in the pie chart, only one stock can be ordered at a time, and there is a problem that placing orders for multiple stocks is time-consuming for the user.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a program, an information processing device, and an information processing method that allow a user to freely adjust the stocks they wish to hold and their ratios, and that reduces the user's effort when placing orders for multiple stocks.

[0019] Hereinafter, each embodiment will be described with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted. This is to avoid the following description becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.

[0020] In addition to the above problems, conventional technologies also have the problem that it is difficult for users to adjust the stocks they want to hold and their composition ratios at the timing they want. In this embodiment, when the users specify each stock that constitutes the total stocks they own and the ratio of each stock to the total stocks, the order contents (i.e., the buy or sell of each stock and the quantity) are determined according to each specified stock and ratio, and orders can be made with this order content, thereby solving this problem.

[0021] Fig. 1 is a schematic configuration diagram of an information processing system according to this embodiment. As shown in Fig. 1, the information processing system S includes terminals 1-1 to 1-N (N is a natural number) according to an embodiment of an information processing device of the present invention, and a computer system 2 connected via a communication network CN.

[0022] The terminals 1-1 to 1-N are used by different users, and are, for example, mobile phones such as multi-function mobile phones (so-called smartphones), tablets, notebook computers, or desktop computers. In this embodiment, an application according to an embodiment of the program of the present invention is installed in the terminals 1-1 to 1-N. Hereinafter, the terminals 1-1 to 1-N are also collectively referred to as terminals 1. In this embodiment, the terminal 1 will be described as a smartphone, as an example.

[0023] The computer system 2 is used by a management organization that manages the information processing system S according to this embodiment, and is, for example, a server. The computer system 2 provides information to the terminals 1-1 to 1-N. The computer system 2 may be a single computer, or may be composed of multiple computers.

[0024] Fig. 2 is an example of a schematic configuration diagram of a terminal according to this embodiment. As shown in Fig. 2, the terminal 1 includes, for example, an input interface 11, a communication module 12, a storage device 13, a memory 14, a display 15, and a processor 16. The input interface 11 accepts an input from a user and outputs an input signal corresponding to the accepted input to the processor 16. The communication module 12 is connected to a communication network CN and communicates with a computer system 2 connected to the communication network CN. This communication may be wired or wireless, but will be described as being wireless.

[0025] The storage device 13 stores an application and various data according to an embodiment of the program of the present invention. As an example, this application is downloaded via the Internet and stored in the storage device 13. This application is an application for users to make investments, and allows the user to freely select the stocks they wish to hold, and to freely adjust the composition ratio of each stock within a total of 100% for a portfolio made up of the multiple selected stocks, thereby setting a target portfolio. Stocks here include individual stocks, bonds, ETFs (Exchange Traded Funds), investment trusts (e.g. real estate investment trusts), legal tender, virtual currencies, commodities (e.g. precious metals such as gold and platinum, energy such as crude oil, The investment target may include at least one of the following investment targets: individual stocks and ETFs. In this embodiment, the brands are described below as examples of individual stocks and ETFs. In addition, the application executes sell and / or buy orders in response to user instructions so that the actual portfolio ratio approaches the set target portfolio. Here, the user instructions include instructions for deposits and deposit amounts, instructions for withdrawals and withdrawal amounts, and instructions for rebalancing.

[0026] The memory 14 temporarily stores data and programs. The memory 14 is a volatile memory, such as a RAM (Random Access Memory). The display 15 displays information according to instructions from the processor 16. The display 17 may be built into the terminal 1 or may be connected externally.

[0027] The processor 16 loads an application from the storage device 13 into the memory 14 and executes a series of instructions contained in the application to display various screens, which will be described later. The detailed processing will be described later.

[0028] Although the terminal 1 will be described as having one processor 16 as an example, the terminal 1 may have two or more processors, and it is sufficient that the terminal 1 has at least one processor.

[0029] Fig. 3 is an example of a schematic configuration diagram of a computer system according to this embodiment. As shown in Fig. 3, the computer system 2 includes an input interface 21, a communication module 22, a storage device 23, a memory 24, an output interface 25, and a processor 26. The input interface 21 accepts an input from an administrator of the computer system 2 (e.g., an employee of a management organization) and outputs an input signal corresponding to the accepted input to the processor 26. The communication module 22 is connected to a communication network CN and communicates with the terminals 1-1 to 1-N. This communication may be wired or wireless, but will be described as being wired.

[0030] The storage device 23 stores programs and various data to be read and executed by the processor 26. The storage device 23 also stores a user ID, which is information for identifying a user, in association with the target portfolio of the user. The memory 24 temporarily holds data and programs. The memory 24 is a volatile memory, such as a RAM (Random Access Memory). The output interface 25 can be connected to an external device and can output a signal to the external device.

[0031] The processor 26 loads a program from the storage device 23 into the memory 24 and executes a series of instructions contained in the program.

[0032] FIG. 4 is an example of a table stored in the storage device 23 of the computer system 2. As shown in FIG. 4, table T1 stores records of pairs of a user ID, which is information for identifying a user, and the target portfolio of the user. Here, the target portfolio includes information regarding the stocks selected by the user and their composition ratios. In the example of FIG. 4, the target portfolio for user ID "00001abc" is 50% stocks with stock code AAAA, 20% stocks with stock code BBBB, 10% stocks with stock code CCCC, 10% stocks with stock code DDDD, and 10% stocks with stock code EEEE. This allows the terminal 1 to refer to the target portfolios of other users.

[0033] <Flow of use by a user (first time)> The flow of use by a user for the first time is as follows. Below, the processing of processor 16 of terminal 1 will be described, and processor 16 will be omitted. (Step S1) Terminal 1 accepts the user's selection of stocks in which the user wants to invest. (Step S2) Terminal 1 initially displays the selected stocks in an equal composition ratio. (Step S3) Terminal 1 accepts adjustments to the ratio of each stock to the user's desired composition ratio. (Step S4) After the user has finalized the portfolio, terminal 1 becomes able to accept order instructions. (Step S5) After confirming the deposit, terminal 1, for example, restricts a commission binding amount from the deposit amount for the purpose of collecting commission, and transmits to computer system 2 instructions for a buy order for each stock at an amount obtained by subtracting the commission binding amount from the deposit amount and multiplying the amount by the ratio of each stock.

[0034] This causes a screen showing the user's portfolio to be displayed, as shown in Fig. 5. Fig. 5 is an example of a screen showing a user's portfolio. As shown in Fig. 5, on screen G1 of terminal 1, stocks in the portfolio currently held by the user and their composition ratios are displayed in a pie chart. Screen G1 also shows the investment profit and loss of each stock in the portfolio.

[0035] <Flow of use by the user (other than the first time)> As an optional process, terminal 1 accepts operations from the user to add, delete, or adjust the ratio of multiple stocks that the user already holds, and after the user selects a stock, accepts operations from the user to adjust the holding ratio of each stock within 100%. As an example, on the adjustment content confirmation screen, terminal 1 displays only the changing ratio, not the amount. As shown in Figure 6, if the total of the ratios does not equal 100%, terminal 1 displays the percentage that must be decreased or increased to reach 100%.

[0036] FIG. 6 is an example of a screen when the target portfolio is being adjusted. Screen G21 in FIG. 6 is an example of a screen when the total of the ratios is less than 100%. In screen G21, "Add 36% to make it 100%" is displayed in the center of the pie chart along with the total ratio of the target portfolio. On the other hand, screen G21 in FIG. 6 is an example of a screen when the total of the ratios exceeds 100%. In screen G22, "Remove 37% to make it 100%" is displayed in the center of the pie chart along with the total ratio of the target portfolio.

[0037] Screen G23 in Fig. 6 is an example of a screen that appears when the total of the ratios is less than 100% and the screen is scrolled down. A banner at the top of screen G23 displays "Add 40% to make it 100%" along with the total ratio of the target portfolio. Meanwhile, screen G24 in Fig. 6 is an example of a screen that appears when the total of the ratios exceeds 100% and the screen is scrolled down. A banner at the top of screen G24 displays "Remove 37% to make it 100%" along with the total ratio of the target portfolio.

[0038] <Calculation principle of order amount at the time of rebalancing, deposit, and withdrawal> FIG. 7 is a schematic diagram showing a calculation image of the order amount at the time of rebalancing, deposit, and withdrawal. As shown in FIG. 7, when the user instructs rebalancing, the processor 16 of the terminal 1, for example, binds a fee binding amount from the current holding amount for fee collection, calculates a target amount (also called a target amount) for each stock by multiplying the amount obtained by subtracting the fee binding amount from the current holding amount by the ratio of each stock in the target portfolio, and determines the buying and selling amount or buying and selling quantity based on the difference between the target amount calculated for each stock and the amount of the holding portfolio. Here, the difference may be the buying and selling amount, or the buying and selling amount may be an amount obtained by increasing or decreasing the amount of a buffer from the difference so that the user's money does not run short. Also, the amount corresponding to the difference may be the buying and selling quantity, or the amount corresponding to the amount obtained by increasing or decreasing the amount of a buffer from the difference so that the user's money does not run short may be the buying and selling quantity.

[0039] As shown in Figure 7, when a user deposits money into a securities account, the processor 16 of the terminal 1, for example, reserves a commission binding amount from the amount obtained by adding the deposited amount to the current holding amount in order to collect commission, calculates a target amount for each stock by multiplying the amount obtained by subtracting the commission binding amount from the added amount by the ratio of each stock in the target portfolio, and determines the buying and selling amount or buying and selling quantity based on the difference between the target amount calculated for each stock and the amount of the holding portfolio.

[0040] Also, as shown in Figure 7, when a user instructs a partial or total withdrawal from a securities account, the processor 16 of the terminal 1, for example, delimits a commission binding amount from the amount obtained by subtracting the withdrawal amount from the current holding amount in order to collect commission, calculates a target amount for each stock by multiplying the amount obtained by subtracting the commission binding amount from the subtracted amount by the ratio of each stock in the target portfolio, and determines the buying and selling amount or buying and selling quantity based on the difference between the target amount calculated for each stock and the amount of the holding portfolio.

[0041] Next, rebalancing instructions and orders will be described with reference to FIG. 8. FIG. 8 is an example of a screen related to rebalancing processing. When Complete is pressed on the adjustment screens G21 to G24 in FIG. 6, the screen transitions to the edit content confirmation screen G31 in FIG. 8. When the "Rebalance" button is pressed on the edit content confirmation screen G31, the screen transitions to the rebalancing instruction screen G32. On the rebalancing instruction screen G32, information on the "current holding ratio", "target ratio", and "necessary ratio correction range" of each stock is displayed based on the difference between the target portfolio and the current portfolio. In this way, the processor 16 of the terminal 1 outputs information for presenting information on the current holding ratio, target ratio, and necessary ratio correction range of each stock on the rebalancing instruction screen. Here, the presentation includes not only display but also a case where the information is notified by voice. When the "Go to order screen" button is pressed on the rebalancing instruction screen G32, the screen transitions to the rebalancing order screen G33. On the rebalancing order screen G33, "either purchase, sale, or all sale", "total transaction amount (also called the buying and selling amount)", and "expected profit and loss" are displayed for each stock. In this way, the processor 16 of the terminal 1 outputs information for presenting the buying and selling price or quantity and expected profit and loss for each stock on the rebalancing instruction screen on the rebalancing order screen. Here, for example, the entries for buy, sell, and sell all are visually highlighted. For example, the color is black under normal circumstances, and the highlighting is a different color, large font, bold, etc. When the "Place Order" button is pressed on the rebalancing order screen G33, the screen transitions to the home screen G34. A pop-up message appears on this home screen G34 indicating that the order has been accepted.

[0042] Fig. 9 is a flow chart showing an example of the processing flow of the terminal. The processing of the processor 16 of the terminal 1 will be described below, and the processor 16 will be omitted. Steps S110 to S160 show the flow of creating a target portfolio. Note that the adjustment of the stocks and ratios shown in steps S110 to S160 is not essential, and depending on fluctuations in stock prices, there may be cases where trading is performed without changing both.

[0043] (Step S110) First, the terminal 1 accepts a brand selection by the user.

[0044] (Step S120) Next, the terminal 1 accepts, for example, adjustment of each stock and its composition ratio of the target portfolio by the user.

[0045] (Step S130) Next, the terminal 1 determines, for example, whether the total of the component ratios is 100%.

[0046] (Step S140) If the total of the composition ratios is not 100% in step S130, an alert is displayed.

[0047] (Step S150) If the total of the composition ratios is 100% in step S130, the terminal 1 determines whether or not the edited content has been confirmed by the user. Specifically, for example, it determines whether or not the "Done" button has been pressed on the screens G21 to G24 as shown in FIG.

[0048] (Step S160) When the edited content is confirmed in step S150 (for example, when the "Done" button is pressed on screens G21 to G24 as shown in FIG. 6), the terminal 1 stores the target portfolio in the storage device 13. The processor 16 of the terminal 1 may also transmit the target portfolio together with the user ID of the user to the computer system 2. As a result, the computer system 2 that receives these updates, for example, the record of the pair of the user ID and the target portfolio in table T1 stored in the storage device 23.

[0049] <Rebalancing Processing> Steps S210 to S260 are processes during rebalancing. (Step S210) The terminal 1 displays, for example, the “Rebalancing” message on the edit content confirmation screen G31 of FIG. It is determined whether the "lance" button is pressed.

[0050] (Step S220) When the "Rebalance" button is pressed in step S210, the terminal 1 determines the rate obtained by subtracting the holding ratio from the target ratio for each stock as the necessary adjustment range and displays it on the rebalancing instruction screen G32 of FIG. 8, for example.

[0051] (Step S230) The terminal 1 determines whether or not the "To order screen" button has been pressed on the rebalancing instruction screen G32 of FIG. 8, for example.

[0052] (Step S240) When the "Go to order screen" button is pressed in step S230, the terminal 1 calculates the buying and selling quantity and / or buying and selling amount for each stock, as described in FIG. 7, for example, and displays the rebalancing order screen G33.

[0053] (Step S250) The terminal 1 determines whether or not the "Place Order" button has been pressed on the rebalancing order screen G33.

[0054] (Step S260) When the "Place Order" button is pressed (i.e. when the terminal 1 accepts a rebalancing instruction), the terminal 1 processes the order and notifies the user that the order has been processed. Here, the order processing is, for example, sending information on the trading volume and / or trading amount of each stock to the computer system 2. As a result, the computer system 2 that receives this information processes the order, for example, at a predetermined timing.

[0055] <Processing When Depositing Money> Steps S310 to S330 are processing when depositing money. (Step S310) The terminal 1 (or the computer system 2) determines whether or not money has been deposited into the securities account.

[0056] (Step S320) If it is determined that the money has been deposited into the securities account, the terminal 1 determines the trading volume and / or trading amount of each issue as described with reference to FIG.

[0057] (Step S330) Next, the terminal 1 processes the order with the purchase and sale quantity and / or purchase price determined for each stock, and notifies the user that the order has been processed. Here, the order process is, for example, sending information on the purchase quantity and / or purchase price of each stock to the computer system 2. In response to this, the computer system 2 receives this information and processes the order, for example, at a predetermined timing.

[0058] <Processing When Withdrawing Money> Steps S410 to S430 are processing when withdrawing money.

[0059] (Step S410) The terminal 1 determines whether or not the "Confirm" button is pressed when the withdrawal amount is specified by the user on the withdrawal instruction screen (not shown), or the "Confirm" button is pressed when the full withdrawal is specified by the user. Here, the state in which the withdrawal amount is specified by the user or the state in which the full withdrawal is specified by the user is also referred to as a specific state.

[0060] (Step S420) If the "Confirm" button is pressed in the above specific state in step S410, the terminal 1 calculates the trading volume or trading amount of each stock as described in FIG. 7 and displays a withdrawal screen (not shown).

[0061] (Step S425) The terminal 1 determines whether or not the "Place Order" button has been pressed on this withdrawal screen.

[0062] (Step S430) When the "Place Order" button is pressed in step S425 (i.e. when terminal 1 accepts a withdrawal instruction), terminal 1 processes the order with the trading volume and / or trading amount determined for each stock, and notifies the user that the order has been processed. Here, order processing involves, for example, sending information on the trading volume and / or trading amount for each stock to computer system 2. In response to this, computer system 2 processes the order at, for example, a predetermined timing.

[0063] In this way, the processor 16 of the terminal 1 accepts an operation by the user to specify a target portfolio including information on stocks and their composition ratios. The processor 16 of the terminal 1 also accepts one of instructions from the user: rebalancing, deposit, or withdrawal. The processor 16 of the terminal 1 then calculates a target amount for each stock by multiplying the amount based on the current holding amount by the ratio of each stock in the target portfolio, and determines the transaction amount and / or the amount of buying and selling for each stock based on the difference between the calculated target amount and the amount of the holding portfolio. Here, the amount based on the current holding amount is an amount corresponding to the current holding amount in the case of a rebalancing instruction (specifically, for example, the amount obtained by subtracting the fee constraint amount from the current holding amount), an amount corresponding to the amount obtained by adding the deposit amount to the current holding amount in the case of a deposit instruction (specifically, for example, the amount obtained by adding the deposit amount to the current holding amount and subtracting the fee constraint amount), and an amount corresponding to the amount obtained by subtracting the withdrawal amount from the current holding amount in the case of a withdrawal instruction (specifically, for example, the amount obtained by subtracting the withdrawal amount from the current holding amount and subtracting the fee constraint amount). In addition, in this embodiment, the timing of this decision has been described as being when one of the instructions for rebalancing, deposit, or withdrawal is received from the user, but it may also be a predetermined timing (for example, the time when the market in which the stock is traded closes, a specified time while the market is closed, or a specified time while the market is open).

[0064] This configuration allows the user to specify a target portfolio including information on stocks and their composition ratios, so that the user can freely adjust the stocks and their ratios that he or she wishes to hold. Furthermore, when the user issues an instruction to rebalance, deposit, or withdraw, the order contents are determined for multiple stocks, so that the user's effort in placing orders for multiple stocks can be reduced. When determining the trading amount or volume for each stock, the trading amount or volume for the stock may be determined based on the price of the stock at the time the instruction to rebalance, deposit, or withdraw is received from the user.

[0065] <Viewing and copying other users' portfolios> Next, a function that allows users to refer to stocks and their composition ratios of other users who use the same application when selecting stocks will be described. FIG. 10 is an example of a list screen of users who are investing in specific stocks. Information about users who are investing in specific stocks is displayed on the list screen G41 of FIG. 10. In this manner, the processor 16 of the terminal 1 outputs information for presenting information about users who are investing in specific stocks. Here, the processor 16 of the terminal 1 may output information for presenting users who are investing in specific stocks on the list screen G41 in order of composition ratio in the target portfolio, or in order of the date on which the specific stock was added or the composition ratio of the specific stock was changed.

[0066] For example, when a user's icon is selected on the user list screen, the screen transitions to the account screen of the selected user as shown in FIG. 11. FIG. 11 is an example of an account screen of another user. On the account screen G42 in FIG. 11, a pie chart displays the rate of increase or decrease in profits over a specified period (e.g., a week), the performance of the investment (e.g., the rate of return), and the number of people using the investment as a reference. On the account screen G42 in FIG. 11, when the "Compare Portfolios" button is pressed, the screen transitions to a portfolio comparison screen G51 in FIG. 12.

[0067] FIG. 12 is an example of a portfolio comparison screen. In the portfolio comparison screen G51 of FIG. 12, the portfolios of other users are displayed, for example, on the right side. When "Learn more about copy" is selected in the portfolio comparison screen G51, a copy explanation screen is displayed in a pop-up as shown in a portfolio comparison screen G52. Also, when the "Copy" button is pressed in the portfolio comparison screen G51, the user's own portfolio is created and displayed with the same stocks and composition ratios as the portfolio of the other user, as shown in a portfolio comparison screen G53. Even after the user's own portfolio is created, the user can adjust the composition ratios and / or add or delete stocks.

[0068] 12, the following processing is executed. When the processor 16 of the terminal 1 receives a user operation to select another user, it requests the portfolio of the other user from the computer system 2. Then, the processor 16 of the terminal 1 receives information about the portfolio of the other user from the computer system 2 in accordance with the request procedure. Then, the processor 16 of the terminal 1 uses the received information about the portfolio of the other user to output information for presenting the portfolio of the other user so that it can be viewed. As a result, the portfolio comparison screen G51 is displayed.

[0069] Next, the processor 16 of the terminal 1 outputs information for presenting the stocks and their composition ratios included in the portfolio of the other user as the portfolio of the user in response to the operation of the user to copy the portfolio of the other user, thereby displaying the portfolio comparison screen G53.

[0070] Next, the processor 16 of the terminal 1 executes a procedure for outputting information to be presented as the user's portfolio, and then executes a process for adjusting the composition ratio and / or adding or deleting stocks in response to the user's operation, thereby enabling the user to create a portfolio of their own choosing.

[0071] FIG. 13 is an example of a change history summary screen of another user's portfolio. When another user checks the portfolio of another user, the change history summary screen G61 displays only the logo as an example of information indicating each stock, and the change history is expressed as a combination of the logo and one of the three categories of addition, deletion, and editing. In order to realize this change history summary screen G61, the processor 16 of the terminal 1 outputs information for presenting the change history in a combination of the stock logo and one of the three categories of addition, deletion, and editing when displaying the change history of the portfolio of another user. This can improve the visibility of the change history.

[0072] When an arrow A61 associated with the changes made on a specific date in the change history is selected on the change history summary screen G61 in Fig. 13, the screen transitions to a change history details screen G62. The change history details screen G62 displays details of the changes made on the specific date. Specifically, for example, the change history details screen G62 displays deleted stocks, and displays the post-edit ratios of the stocks along with added and edited stocks.

[0073] <Editing on the management screen> FIG. 14 is an example of a management screen where a user manages his or her own portfolio. When a target stock is swiped left on the management screen G71 of FIG. 14, a delete button is displayed. When this delete button is selected (e.g., tapped), the target stock is deleted. At this time, if the user does not hold the stock to be deleted, it is completely deleted from the stock list as shown in management screen G72. On the other hand, if the user holds the stock to be deleted, the stock to be sold is displayed, for example, at the bottom of the list as shown in management screen G73. When "Undo" is selected (e.g., tapped) in the screen displayed as a pop-up on management screen G72 or G73, the deleted stocks are displayed at the ratio before deletion as shown in management screen G74.

[0074] In this way, when an operation to delete a target stock is performed (for example, by tapping the delete button that appears after swiping the target stock), the processor 16 of the terminal 1 may display the stock as "planned for sale" if it is already held, or delete it from the screen if it is not held.

[0075] When the holding ratio of the stock to be sold is edited in the management screen G73 and the holding ratio of the stock to be sold becomes 1% or more, the display of "Stock to be sold" is erased, for example, as shown in the management screen G75.

[0076] In the management screen for managing a portfolio, when the ownership ratio of a stock held is set to 0% by a user operation, the processor 16 of the terminal 1 may display it as 0% regardless of whether the stock is held or not. After the user completes editing, the processor 16 of the terminal 1 may display the stock as a stock to be sold if it is held.

[0077] In the management screen for managing the portfolio, the stocks held may be displayed in order of value. This is because stocks that have not yet been sold and are scheduled to be sold are ranked at the top, so it may not be appropriate to know the latest situation. At the stage where a user adds a new stock and sets an arbitrary holding ratio but has not yet placed an order (i.e., a holding ratio is set but the user does not actually hold the stock), the processor 16 of the terminal 1 may display "In operation" on the holding ratio confirmation screen for that user.

[0078] As described above, the application installed on the terminal 1 in this embodiment is a program that causes the terminal 1, which is an example of a computer, to execute the following procedures: accepting an operation in which the user specifies a target portfolio including information on stocks and their composition ratios; accepting one of instructions from the user, from among rebalancing, deposit, and withdrawal; calculating a target amount for each stock by multiplying an amount based on the current holding amount by the composition ratio of each stock in the target portfolio, and determining the transaction amount or buying and selling volume for each stock based on the difference between the calculated target amount and the amount of the holding portfolio.

[0079] This configuration allows the user to specify a target portfolio including information on stocks and their composition ratios, so the user can freely adjust the stocks and their ratios that he or she wishes to hold. Furthermore, when the user issues an instruction for rebalancing, deposit, or withdrawal, the order details for multiple stocks are determined, so the user's effort in placing orders for multiple stocks can be reduced.

[0080] At least some of the functions of the terminal 1 described in the above embodiment may be configured with hardware or software. In the case of configuring with software, a program that realizes at least some of the functions of the terminal 1 may be stored in a computer-readable recording medium and read and executed by a computer. The recording medium is not limited to a removable one such as a magnetic disk or an optical disk, but may be a fixed recording medium such as a hard disk device or a memory.

[0081] Also, a program for realizing at least a part of the functions of the terminal 1 may be distributed via a communication line (including wireless communication) such as the Internet. Furthermore, the program may be encrypted, modulated, or compressed and distributed via a wired line or wireless line such as the Internet, or stored in a recording medium.

[0082] At least some of the functions of the terminal 1 may be realized by the computer system 2. Furthermore, the computer system 2 may be made to function by one or more information devices. When multiple information devices are used, one of the devices may be a computer, and the computer may execute a predetermined program to realize the functions as at least one of the means of the computer system 2.

[0083] In the method invention, all the steps may be realized by automatic control using a computer. Alternatively, each step may be performed by a computer while the progress between steps is controlled manually. Furthermore, at least some of the steps may be performed manually.

[0084] As described above, the present invention is not limited to the above-described embodiment as it is, and in the implementation stage, the components can be modified and embodied without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining the multiple components disclosed in the above-described embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, components from different embodiments may be appropriately combined.
