Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a technology for providing a securities portfolio.

[0002]

2. Description of the Related Art Securities companies deal in stocks, receivables, investment trust products and the like. In particular, investment trust products are portfolios that have been standardized by investment trust companies by combining multiple securities from specialized skills, know-how, and extensive economic information. Investment trust products can be purchased. In selecting investment trust products, in addition to its performance, consideration is given to whether it is stable operation or a type of pursuit of rising profits, and the nature of surplus funds, such as when it is necessary to convert to cash. In this way, the customer examines the performance and characteristics of the investment trust product and decides whether to purchase it by judging whether or not it matches its investment strategy. However, the degree of freedom is limited because the proposed portfolio is standardized.

[0003] On the other hand, when purchasing individual stocks or receivables, the risk can be reduced by combining a plurality of brands using the advice of a securities company window or telephone service. In this case, the customer can invest mainly in his favorite brands. The advice is based on the knowledge and know-how of an experienced person, and is accompanied by a profit.

[0004] However, going to a store of a securities company or receiving advice on an investment strategy by telephone requires some degree of transaction, and it is difficult to do so unless the trusting relationship with the person in charge is sufficient. .

[0005] Under such an environment, investment management focusing on the brands selected by oneself is carried out mechanically, that is, without consulting with the person in charge at the store or telephone service, the abundant transaction information held by securities companies and the like is obtained. It is desired to make a proposal based on optimization.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and allows a user to freely select a major investment brand and easily construct an optimal portfolio based on a wealth of transaction information. It aims to provide a portfolio providing technology that can be used.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention employs a configuration as described in the claims. Here, the claims will be described with some supplements.

Receiving an optimal portfolio based on the security issues and the total purchased funds according to a predetermined rule; presenting the determined optimal portfolio; and purchasing the presented optimal portfolio. And receiving a confirmation input.

In this configuration, an optimal portfolio is determined in accordance with a predetermined rule in response to designation of a security issue by a user and designation of total funds. The predetermined rules can employ various financial engineering techniques, and can determine an optimal portfolio based on securities company data, for example, past returns and risk data. Users can build a portfolio around the issues they choose, and the portfolio is backed by sufficient data and the latest financial engineering, and is highly reliable. further,
There is no need to go to a securities company store or the like and receive advice from the person in charge.

[0010] The optimal portfolio may be determined in consideration of the portfolio holding period. Further, the number of brands allowed to be included in the portfolio in addition to the brand specified by the user may be specified, and the optimal portfolio may be determined by taking this into consideration.

The optimal portfolio can be determined from various viewpoints, and can be selected by designating return, risk, or both.

The present invention can also be realized as a securities portfolio providing device, and a part thereof can be realized as computer software. The present invention can also be configured by connecting a client device and a server device for providing a securities portfolio via a network. The client device may be configured as a web browser, for example, and the server device may be configured as a web server. The web server provides a service to the client device in cooperation with, for example, an application server or a database management system. Note that the technical scope of the present invention includes a recording medium on which the above-described computer software is recorded.

[0013]

Embodiments of the present invention will be described below. This embodiment uses a CTI (Computer Telephony Integrated) center to request the provision of a portfolio by voice. The speech is recognized and processed by a speech recognition system. Of course, it is also possible to use an Internet homepage.

FIG. 1 shows the portfolio providing system of this embodiment as a whole. In this figure, a telephone set 100 is connected to a service provider's CTI center 300 via a subscriber telephone network 200. Telephone 10
0 may be a fixed telephone or a mobile telephone (mobile station for mobile communication). Alternatively, a web browser with a voice input (telephone) function may be used (see FIG. 2). CTI Center 300
Are a CTI server 301, an automatic voice response device 302, a voice recognition server 303, an application server 304,
It is configured to include a database management system 305 and the like. The database management system 305 manages various databases 306 such as a customer database and a stock database (stock information such as returns and risks of listed stocks, performance information of a company, etc.). Voice recognition server 3
03 is for recognizing the voice input from the telephone 100 and outputting it as text data. Preferably, the speech recognition server 303 is suitable for recognizing an unspecified speaker. The vocabulary may be limited, such as stock issues. The application server 304 performs various processes associated with providing a portfolio based on the recognition result of voice recognition from the telephone. Various processes will be described later with reference to FIG.

Note that, in this example, the provision of the portfolio is requested using the telephone 100, but a similar request can be made using the web browser 400 as shown in FIG. In this case, the input from the user is performed using the web browser 400, and the input is performed using the Internet 401, the router 402, the web server 40,
3 to the application server 304. In this case, since the input is performed using a keyboard or a mouse device, voice recognition is not necessarily required. However, a voice recognition function may be used in a situation where voice input is preferable, such as brand input. In this case, the voice input is executed via the web browser 400, for example. In FIG. 2, FIG.
Corresponding reference numerals are given to portions corresponding to and the detailed description will not be repeated.

FIG. 3 shows the operation of this embodiment.
In this figure, a user calls the access point of the CTI center 300 to start processing. In this figure, only the main steps will be described, but it goes without saying that there may be other auxiliary steps.

First, a user ID is input (S1).
0). That is, the automatic voice response apparatus 302 prompts the user to input a user ID by voice, and the user notifies the user ID using voice input or a push button of a telephone. When the user ID is input by voice, voice recognition is performed. If the user ID is not registered, the subsequent processing is prohibited. In some cases, the process may proceed to a user registration service.

Next, a password is input (S1).
1). That is, the automatic voice response apparatus 302 prompts the user to input a password by voice, and the user notifies the password by voice input or by using a push button of a telephone. Also in this case, voice recognition is performed at the time of voice input.
Further processing is prohibited even when the password is not proper.

Next, a service is specified (S12).
That is, the automatic voice response apparatus 302 guides the user by voice to the service, and prompts the user to input the number of the corresponding service. The user enters the corresponding service number.
The number may be input by voice and the voice may be recognized. Although various services are assumed, here, only the portfolio providing service will be referred to. Processing after step S13 is processing of a portfolio providing service.

Next, a brand to be included in the portfolio is input (S13). First, the automatic voice response device 3
02 prompts the utterance of the brand name. For example, the user is informed that "Please input your favorite brands sequentially by voice. When the input is completed, press the # button." The user voice-inputs desired brands to be included in the portfolio in order. This voice input is recognized by the voice recognition server 303.

Next, the number of other brands to be included in the portfolio (which brand is automatically selected from preset brands by the system) is designated (S1).
4). First, the automatic voice response apparatus 302 prompts the input of the number of brands of other brands. The input may be a voice input or the telephone 1
A 00 push button may be used. At the time of voice input, voice recognition is performed. As other issues, issues that are preferably incorporated in constructing a portfolio are selected in advance. If various types of stocks are selected in advance, it becomes easy to select the most suitable one for building a portfolio. Of course, a portfolio may be constructed using only the specified brands. In this case, "0" is input. In some cases, services may be provided without this step. That is, the service may be a service that builds a portfolio only with brands designated by the user.

Next, the total investment amount is input (S15). First, the automatic voice response apparatus 302 prompts the input of the total investment amount by voice. The user designates the total investment amount using voice input or a push button of the telephone 100. At the time of voice input, voice recognition is performed.

Next, an investment period is input (S16). First, the automatic voice response apparatus 302 prompts an input of an investment period by voice. The user designates the investment period using voice input or a telephone push button. At the time of voice input, voice recognition is performed. The total investment amount may be divided and the investment period may be designated for each part.

Next, a target return is input (S1).
7). First, the automatic voice response apparatus 302 prompts the user to input a target return by voice. User inputs voice (voice recognition)
And the target return using the push button on the phone.

Next, a target risk is input (S18).
First, the automatic voice response apparatus 302 prompts input of a target risk by voice. The user specifies a target risk using voice input (voice recognition) or a push button on a telephone.

Next, a candidate portfolio is determined (S
19). That is, the application server 304 determines the candidate portfolio based on the user input. A method for determining a candidate portfolio will be described later with an example.

Next, the candidate portfolio is guided to the user by voice. At this time, issues included in the candidate portfolio are guided, and planned returns and planned risks are guided. A guidance may be given to a plurality of candidate portfolios to prompt the user to make a selection.

Finally, the user determines a candidate portfolio (S20). First, the automatic voice response apparatus 302 prompts for confirmation, and the user confirms or rejects using voice input (voice recognition), a telephone selection, or a confirmation push button. If the user rejects the confirmation, the user is prompted to re-enter the option or cancel the service. Re-entering options can be, for example, entering total investment,
Input of a target return, input of a target risk, input of a brand name, input of the number of other brands, and the like. When re-input is performed, a candidate portfolio is determined in the same manner.

Next, the setting of the candidate portfolio will be described. Here, a description will be given on the assumption that the CTI center 300 can use data of a securities company. Securities companies usually hold the return Ei and the risk σi (standard deviation) of each information brand for at least 20 years or more and update the data every day. Here, the portfolio is optimized using such data.

Now, taking the portfolio of two companies as an example, the return E _p and the risk σ _p are obtained by the following equations.

[Number 1] _{E p = x 1 E 1 +} x 2 E 2 (1) where _x 1, _{x 2} is the investment ratio to each brand, _{x 1} +
x ₂ = 1.

[Number 2] _{^{σ p 2 = x 1 2 σ}} 1 2 + x 2 2 σ 2 2 + 2x 1 x 2 σ 1,2 (2) where sigma _{1, 2} are two companies covariance, two companies Is ρ
_1,2 expressed by a correlation coefficient of _{≡σ 1,2 / σ 1 · σ 2} .
Using this to rewrite σ _p

The Equation 3] _{^{σ p 2 = x 1 2 σ}} 1 2 + x 2 2 σ 2 2 + 2x 1 x 2 ρ 1,2 · σ 1 · σ 2 (3). This is shown in a graph in FIG. 4,
The curve changes as indicated by the arrow according to the correlation coefficients ρ _1,2 of the two brands. From this figure, a point where the return is large and the risk is small is required.

Therefore, the optimum investment ratio x is obtained based on the E-σ curve as shown in FIG.

(Equation 4) here

(Equation 5) V is the variance / covariance matrix of each issue,

(Equation 6) (1, E) is

(Equation 7) Is the determinant. A is called the portfolio information matrix,

(Equation 8) Here, the investment ratio x is obtained by taking examples of the companies A, B, and C (FIG. 5). Figure 5 shows the variance and covariance of Company A, Company B and Company C
And the variance / covariance matrix v is as follows.

[Equation 9] The values of a, b and c are

(Equation 10) And the portfolio information matrix A is as follows.

[Equation 11] Substituting this portfolio information matrix A into equation (4),
The investment ratio x is obtained as follows.

(Equation 12) If the target return E _p substituted for this value can be obtained investment ratio. From the above equation, the investment ratio can be obtained from the return E for the brand selected by the user.

[0032] It should be noted that, after the portfolio has been purchased to the user, as compared to the user's specified time period in return E, and the actual E _p to update the data of risk σ, and E _p on the calculation that the expected The portfolio may be sold when a predetermined condition is satisfied.

In the above example, the investment ratio is obtained from the return and the risk. However, it is also possible to predict the future trend and determine the optimum investment ratio for the holding period.

In the above example, the number of brands is one. However, when a brand specified by the user is combined with a predetermined number of other brands, a portfolio is created with a plurality of combinations, and returns are made in the portfolio. And one or more portfolios that are preferred in terms of risk and risk.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified. For example, in the above description, the portfolio is provided via the CTI center or the web server. However, the portfolio may be provided similarly in a client-server system in a normal LAN. In this case, for example, a person in charge of a securities company or the like may input a brand, a return, a risk, and the like according to a customer's request and receive the contents of the portfolio.

Further, as shown in FIG. 6, a product name or a service name may be inputted, and a related company (brand) may be searched and designated by the name.

When a web browser or the like is used, as shown in FIG. 7, when a portfolio is guided, company information, company performance, stock transition chart, etc. of a selected brand may be displayed. The user may determine whether to purchase the portfolio based on this display.

After purchasing the portfolio,
As shown in FIG. 8, the products and services of the brand companies included in the purchase portfolio may be presented, and the products and services may be purchased through the presentation screen. When a product or service is purchased, statistical data such as the number of sales may be provided to the user. It should be noted that the flow of the processing in FIGS. 6, 7 and 8 itself is clear from the drawings, and thus detailed description will not be given.

In addition, instead of using stock trading units as units usually traded in the market, in small transactions (for example, cumulative stock investments of securities companies, so-called “ruitou”), a portfolio is constructed in small units. Of course, you can do that.

[0040]

As described above, according to the present invention, it is possible to easily build and provide a portfolio supported by a wealth of information and financial engineering while incorporating brands desired by customers.
