[0273] In the example shown in the figure, the stock card display area 1126 is displayed on the display of the terminal 10 so that there is a blank area where the stock card display area 1126 is not displayed, but it is also possible to display the stock card display area 1126 across the entire screen.

[0274] The uninterested operation accepting section 1128 is an operating member that accepts an operation to evaluate the presented brand as "uninterested" by tapping.

[0275] The watchlist entry operation receiving unit 1130 is an operation member that receives an operation to evaluate a presented stock by tapping to "register it on the watchlist."

[0276] The purchase intention operation receiving unit 1132 is an operation member that receives an operation of rating the presented stock by tapping to the effect that "I want to buy."

[0277] The operation content display area 1134 is an area that displays the content of an operation when the user is trying to move a card by swiping it and evaluate it.

[0278] In the illustrated example, the operation content display area 1134 indicates that the user is about to rate the card "I want to buy" in response to a swipe of the card to the right. Also, while the swipe operation is depicted to move the card, a card corresponding to another stock is displayed on the back side to indicate that the next card will be presented for rating.

[0279] Summary information display area 1136 is an area that displays additional information about the stock.

[0280] In the illustrated example, the summary information display area 1136 displays the results of generating stock information using a large-scale language model, and displays a message indicating that the information was generated using a large-scale language model.

[0281] The company information display area 1138 is an area where information about the stock is displayed.

[0282] In the illustrated example, the company information display area 1138 displays information provided to investors, such as market capitalization.

[0283] <Second embodiment> The second embodiment will be described below.

[0284] <Data Structure of the Second Embodiment> 21 is a diagram showing the data structure of the benchmark stock database 215. The benchmark stock database 215 includes an item "index ID," an item "time of index establishment," an item "component stocks and weight allocation," an item "index value," an item "index calculation date," an item "divisor parameter," an item "presence or absence of stock split," and an item "adjustment by dividend."

[0285] The item "index ID" is information that identifies each parameter calculated according to the stock group that constitutes the index.

[0286] More specifically, the item "index ID" is identification information that is issued according to the timing of calculating the index (once a day in the illustrated example).

[0287] The item "Indicator setting time" is information on the time when the stock group that constitutes the indicator is extracted and the indicator is calculated for the extracted stock group.

[0288] In the illustrated example, the item "index setting time" indicates that the stocks that make up the index are replaced every certain period (for example, every three months).

[0289] The item "Constituent stocks and weight allocation" is information on the group of stocks that make up the index and the weighting determined for each stock.

[0290] In the example shown, the item "Constituent Stocks and Weight Allocation" shows an example in which the stocks that make up the index are replaced at regular intervals as described above, and at the same time, the weighting of each stock that makes up the index is also calculated.

[0291] As described above, the server 20 extracts stocks that make up the index, weights the extracted candidate stocks (weight allocation), and periodically replaces stocks (rebalances). Specifically, the server 20 calculates the candidate stocks that make up the index and their weights every quarter using the following method.

[0292] (1) Extraction of stocks that make up the index (step S2223 in FIG. 22, which will be described later) For each stock that server 20 makes available for trading to users, the following calculation is performed to determine the market capitalization (hereinafter sometimes referred to as "value") of each stock within the service based on the trading performance of each user of the service provided by server 20.

[0293] Value of a certain stock = current value of the trading price of that stock (e.g., stock price) × total number of stocks held by each user of the service provided by the server 20 (item "portfolio" of the user database 211) Once the value of each stock is identified, a certain number of stocks (for example, 30 stocks) are selected from the top based on their value as candidate stocks to be included in the index.

[0294] (2) Calculation of weighting (weight distribution) for the extracted candidate stocks (step S2225 in FIG. 22, which will be described later) The server 20 calculates a total value by adding up the values ​​of each of the extracted fixed number of brands.

[0295] The server 20 calculates the weighting (share in the index) of each stock as follows:

[0296] Weighting of extracted candidate stocks (%) = Value of non-party candidate stocks / Total calculated value In this way, based on the holdings of each stock by each user within the service, the market capitalization (value) of each stock within the service is calculated, and the stocks that make up the index are extracted, and the ratio of the value of a specific stock to the total value of the stocks that make up the index is calculated as the share (weighting) of that specific stock.

[0297] The item "index value" is information on parameters calculated from the current trading value of each stock that constitutes the index and the weighting of each stock.

[0298] In the illustrated example, the item "index value" indicates that the index is calculated once a day.

[0299] Following the above (1) extraction of stocks that make up the index (step S2223 in Figure 22 described later) and (2) calculation of weighting (weight distribution) of the extracted candidate stocks (step S2225 in Figure 22 described later), we will now explain how the server 20 calculates the index.

[0300] (3) Calculation of the initial value of the index When calculating an index based on the candidate stocks extracted as described above, the server 20 selects a divisor so that the initial value is a fixed value (for example, the initial value of the index is set to 1000).

[0301] Divisor for Initial Value = Total Value calculated in (2) / Constant Value (for example, if the initial value of the indicator is 1000, the constant value is 1000)

[0302] (4) Calculation method of the index When calculating the index (for example, once a day), the server 20 calculates a value obtained by multiplying the current value of the trading price (for example, stock price; values ​​such as the opening price and closing price for the day may be used) of the candidate stock that constitutes the index by the weighting of that candidate stock (using the weighting value calculated when the candidate stock is extracted).By summing up the values ​​calculated for each candidate stock in this way, the server 20 obtains "the result of performing a calculation for all candidate stocks based on the stock price and weighting of the trading price of the candidate stock."

[0303] The server 20 calculates the index value as follows.

[0304] Index value = Calculation result for all candidate stocks based on the stock price and weighting of the candidate stocks' trading prices / Divisor parameter The divisor parameter is adjusted in accordance with the rebalancing of the stocks that make up the index, as described below.

[0305] The item "index calculation date" is information about the timing of calculation of a parameter representing an index.

[0306] In the illustrated example, the item "index calculation date" indicates an example in which the index is calculated at a predetermined cycle (for example, once a day).

[0307] The item "Divisor Parameter" is information on an adjustment parameter that represents an index and is calculated according to the timing of calculation as appropriate, to make the parameter (index value) continuous even before and after the replacement of the stocks that make up the index.

[0308] More specifically, the item "divisor parameter" sets the divisor parameter so that the index value calculated in accordance with (4) above will be continuous before and after the replacement of the stocks that make up the index.

[0309] The item "Stock split or not" is information on the degree of influence of a stock split at the timing of calculating the index.

[0310] More specifically, the item "Stock Split" is information for adjusting the index value for corporate actions that affect the index. In the example shown, the item "Stock Split" holds information on the timing of calculating the index value (information identifying stocks that have undergone stock splits, associated with the item "Index Calculation Date"), and information on the number of splits. The item "Adjustment by dividends" is information on the degree of influence of dividend payments on the timing of calculating the index. More specifically, the item "Dividend Adjustment" is information for adjusting the index value for corporate actions that affect the index. In the example shown, the item "Dividend Adjustment" stores information for identifying stocks, information on dividends per share for stocks that pay dividends, and information on the impact on the index that is calculated based on this information, in association with the ex-dividend dates of the stocks (associated with the item "Index Calculation Date"). (5) Adjustments in response to events occurring in the stocks that make up the index For example, if a candidate stock is split due to a stock split, the parameters of the market value of the candidate stock's trading price when calculating the index are adjusted based on the split ratio. For example, if there is a stock that splits one share into two shares due to a stock split, the stock price when calculating the index value is multiplied by a ratio according to the number of splits (2x if one share is split into two shares), and that weighting is applied. This allows the continuity of the index value to be maintained.

[0311] In addition, for stocks that pay dividends, the dividend per share (dividend payout rate) is used to adjust the index on the ex-dividend date. For example, for a stock that goes ex-dividend, the dividend per share, the total number of shares held by each user, and the weighting of that stock are multiplied to calculate a value indicating the impact of the stock's ex-dividend on the index. If multiple stocks go ex-dividend on the same day, a value indicating the impact on the index for each stock is calculated and added together. The value indicating the impact of the ex-dividend on the index is applied to the index calculated using formula (4) above (the sum of these is calculated). This allows for the continuity of index values ​​calculated according to the trading price of each stock to be maintained in response to corporate actions such as stock splits and ex-dividends.

[0312] <Flow of the second embodiment> FIG. 22 is a diagram showing the flow of processing for extracting stocks that constitute an index and calculating an index based on the extracted stocks.

[0313] The server 20 is configured to store information on the user's holdings of each stock (each user's portfolio) in the user database 211 of the memory unit 202 in response to each user's buying and selling of the stocks that are the subject of trading.

[0314] In step S2221, the index calculation module 2048 of the server 20 calculates parameters for evaluating each tradable stock based on the trading price of that stock and the total number of stocks held by each user. The index calculation module 2048 performs processes such as extracting stocks that make up the index and determining the weighting of each stock at regular intervals (for example, every three months, which is a quarter). More specifically, as described above, the index calculation module 2048 identifies, for each stock, the market capitalization (the above-mentioned "value") according to the investment status of each user of the service provided by the server 20 and the holding status of each stock.

[0315] In step S2223, the index calculation module 2048 of the server 20 extracts a predetermined number of stocks (for example, the top 30 stocks) with the highest parameter values ​​as candidate stocks to constitute the index based on the parameters calculated for each stock (the value of each stock).

[0316] As described above, the index calculation module 2048 extracts a predetermined number of stocks as candidate stocks from stocks that are the subject of buying and selling transactions, based on at least the number of stocks held by each user.

[0317] More specifically, the index calculation module 2048 extracts a predetermined number of stocks as candidate stocks based on the trading price (stock price) of each stock and the total number of stocks held by each user.

[0318] More specifically, the index calculation module 2048 identifies the parameters of each stock by multiplying the trading price of each stock by the total number of stocks held, and compares the parameters identified for each stock to extract a predetermined number of stocks with the highest parameters as candidate stocks.

[0319] In step S2225, the index calculation module 2048 of the server 20 sums up the parameters (values) calculated for the candidate stocks that make up the index (a predetermined number of stocks as described above) and obtains the total value. The index calculation module 2048 calculates the ratio of the calculated parameter for each candidate stock to the total value and stores the calculated result as a weighting (share) for each candidate stock.

[0320] In this way, the index calculation module 2048 determines the weighting of each candidate stock in calculating the index based on the parameters (values) specified for each candidate stock. Here, in determining the weighting, the index calculation module 2048 obtains an aggregate parameter by adding up the parameters specified for each candidate stock for all candidate stocks, and determines the ratio of each candidate stock's parameter to the aggregate parameter as the weighting for each candidate stock.

[0321] In this way, the index calculation module 2048 determines the combination of candidate stocks that make up the index and the weighting of each candidate stock.

[0322] In step S2227, the index calculation module 2048 of the server 20 obtains a value for each candidate stock by multiplying the trading price of the candidate stock by the weighting for that candidate stock. The index is calculated by summing these values ​​and reflecting the adjustment parameter. More specifically, the index calculation module 2048 calculates the index by dividing the sum by a predetermined divisor as the adjustment parameter.

[0323] More specifically, the index calculation module 2048 calculates an index that fluctuates according to the market price of each candidate stock based on the market price of each of the predetermined number of extracted candidate stocks.

[0324] The index calculation module 2048 calculates an index based on the determined weighting of each candidate stock and the trading price of each candidate stock. More specifically, the index calculation module 2048 obtains an index by multiplying the determined weighting by the trading price for each candidate stock and summing up the multiplied values ​​obtained for each candidate stock.

[0325] Furthermore, the index calculation module 2048 may adjust and calculate the index for the candidate stocks that constitute the index in accordance with corporate actions such as dividend payments and stock splits. For candidate stocks that have paid dividends, the index calculation module 2048 may calculate the index based on the market value of the trading price of the candidate stock and the dividend payout rate for the dividend. For candidate stocks that have undergone a stock split, the index calculation module 2048 may calculate the index based on the market value of the trading price of the candidate stock and the number of splits for the split.

[0326] As explained above, the index calculation module 2048 performs a process of extracting a predetermined number of stocks as candidate stocks every certain period. During this certain period, the index calculation module 2048 calculates indexes without changing the extracted candidate stocks, sets adjustment parameters to adjust the calculated indexes so that they are continuous even when the candidate stocks are replaced before and after the replacement every certain period, and applies the adjustment parameters to calculate the indexes after the candidate stocks are replaced.

[0327] In step S2229, the index calculation module 2048 of the server 20 notifies the user that the candidate stocks have been extracted and the index has been calculated. For example, the index calculation module 2048 may notify the user that the candidate stocks have been replaced and information on the weighting of the candidate stocks after the replacement, each time the timing (every fixed period) for replacing the candidate stocks that make up the index arrives.

[0328] In step S2211, the terminal 10 displays that the candidate stocks have been extracted and the indexes have been calculated.

[0329] FIG. 23 is a diagram showing the flow of processing for trading stocks that constitute an index by accepting an operation to trade by specifying an index.

[0330] In step S2321, the stock trading module 2046 of the server 20 presents an operation screen for trading stocks to the user of the terminal 10. The operation screen displays an index calculated according to the trading price of the stock and an operation section for accepting trades based on the index. In this way, the stock trading module 2046 presents the index calculated by the index calculation module 2048 to the user. The stock trading module 2046 presents the name of the calculated index to the user as the object of trading.

[0331] In step S2311, the terminal 10 accepts an operation to trade based on the indicator from the user. More specifically, the terminal 10 accepts an operation to place a buy order or an operation to place a sell order from the user based on the indicator.

[0332] In step S2323, the stock trading module 2046 of the server 20 accepts an operation to trade based on the index, and determines the allocation of the trading amount to each candidate stock according to the trading amount.

[0333] In this way, the stock trading module 2046 receives from the user an operation to buy or sell a name related to an index as the subject of the transaction, and in response to receiving from the user an operation to buy or sell a name related to an index, executes a transaction for the user involving at least one of the candidate stocks that make up the index.

[0334] Here, in response to receiving an operation from a user to buy or sell a name related to an index, the stock trading module 2046 may set the trading amount for trading each candidate stock based on the weighting of each candidate stock that makes up the index, and may conduct trading for each candidate stock based on the trading amount set for each candidate stock.

[0335] In addition, in response to receiving an operation from a user to buy or sell a name related to an index, the stock trading module 2046 may set the trading amount for trading each candidate stock by equally allocating the trading amount for the buying or selling operation to each candidate stock that constitutes the index, and may conduct trading for each candidate stock based on the trading amount set for each candidate stock.

[0336] In step S2325, the stock trading module 2046 of the server 20 executes trading of each candidate stock in accordance with the allocation of the trading amount to each of the candidate stocks constituting the index. For example, the stock trading module 2046 may execute trading of each candidate stock in a bilateral transaction with a user in accordance with the current stock price of each candidate stock and the allocation of the trading amount to each candidate stock, or may execute trading of each candidate stock in accordance with the allocation of the trading amount to each candidate stock by a market order or the like on the open market.

[0337] In step S2327, the server 20 presents the results of the trades of each candidate stock to the user of the terminal 10.

[0338] In step S2313, the terminal 10 displays the results of the transaction based on the index.

[0339] <Example of a screen in the second embodiment> FIG. 24 is an example of an operation screen that displays an index and accepts transactions based on the index.

[0340] The trading operation screen 2400 is an operation screen for accepting operations for buying and selling orders targeting an index.

[0341] The transaction operation screen 2400 corresponds to each process such as steps S2321 and S2311 in FIG.

[0342] The index value display area 2402 is an area for displaying the calculated index.

[0343] In the illustrated example, the index value display area 2402 displays the calculated index value, the timing of calculation (for example, if the index is calculated once a day, the date the index was calculated), and the increase or decrease from the previous calculation.

[0344] In the illustrated example, the time-series data of the index calculated by the index calculation module 2048 is displayed in chart format. However, a chart of the time-series data of another benchmark index (e.g., an index index such as the Nikkei Average or the S&P 500, or a specific stock) may also be displayed together to enable comparison with the performance of the index calculated by the index calculation module 2048. Although not illustrated, an operation member for specifying the other benchmark index may be displayed together with the chart display area 2408 on the trading operation screen 2400, and the specified other index and the index calculated by the index calculation module 2048 may be displayed in the chart display area 2408 in accordance with a user's operation of the operation member. In this way, by displaying an index of the most popular stocks (an index calculated by the index calculation module 2048) and an index of a general index in a comparable manner to each user of the service provided by the server 20, an opportunity to refer to the investment behavior of other users (such as the trading history of stocks, each user's portfolio, etc.) can be provided, which may encourage interaction between users of the service provided by the server 20.

[0345] The index portfolio confirmation operation unit 2404 is an operation member that accepts an operation to confirm each stock that constitutes the index.

[0346] In the illustrated example, the index portfolio confirmation operation unit 2404 displays the stocks that make up the index and the weighting of each stock by overlaying, outputting a separate window, or the like, in response to a user operation.

[0347] The sector confirmation operation section 2406 is an operation member that accepts an operation to display each stock that constitutes an index by industry sector.

[0348] In the illustrated example, the sector confirmation operation unit 2406 may classify candidate stocks into sectors into which each stock is pre-classified, such as "semiconductor-related," "services and software," "automotive industry," "pharmaceutical industry," etc., in response to user operation, and display the total value obtained by adding up the weightings of each candidate stock for each sector.

[0349] The chart display area 2408 is an area for displaying a chart showing the time series transition of index values.

[0350] In the illustrated example, the chart display area 2408 displays a chart for 30 days, which is the period specified in the display period specification section 2416.

[0351] The stock extraction details display area 2410 is an area that displays the details of an event when an event related to the calculation of an index occurs.

[0352] The stock extraction details display area 2410 may display the contents of events related to the calculation of the index, and may include the following: - The replacement of stocks that make up the index (rebalancing) and the timing (date of rebalancing) - The calculated index value has been adjusted due to corporate actions regarding the stocks that make up the index (for example, the stock split mentioned above). The issue confirmation operation unit 2412 is an operation member that accepts an operation to check the history of the candidate issues that make up the index.

[0353] More specifically, the stock confirmation operation unit 2412 displays information on past stocks that make up the index, with the breakdown of the stocks that make up the index separated according to the time of rebalancing, in response to user operations (for example, if the stocks that make up the index are replaced every three months, the stocks that make up the index will be maintained for three months, so the history of replacement of stocks that make up the index every three months in the past can be distinguished).

[0354] The time-series data confirmation operation unit 2414 is an operation member that accepts an operation to confirm the time-series data of the index value.

[0355] More specifically, the time series data confirmation operation unit 2414 displays the history of index values ​​for each timing at which the index is calculated (for example, if the index is calculated once a day, the index value for each day) in response to user operation.

[0356] The display period designation section 2416 is an operation member that accepts designation of the period for displaying the chart.

[0357] In the illustrated example, the display period designation section 2416 displays a chart of the time series change in the index value for a "30 day period," but any period may be designated.

[0358] The sell order operation unit 2418 is an operation member that accepts an operation for a sell order from the user targeting the name of an index.

[0359] In the illustrated example, the sell order operation unit 2418 displays that the user holds each stock that constitutes the index, and that sell orders can therefore be placed. Alternatively, if the user does not hold each stock that constitutes the index, the sell order operation unit 2418 may display this fact and not accept sell orders.

[0360] The selling price of each stock constituting the index may be determined based on the amount specified by the user and, for example, the weighting (%) of each stock constituting the index, in response to a user's operation on the sell order operation unit 2418. The server 20 may accept buying and selling of stocks in bilateral transactions with users, thereby accepting transactions of decimal shares.

[0361] Furthermore, in response to a user's operation on the sell order operation unit 2418, an upper limit on the amount of a sell order that can be placed may be set according to the number of stocks held by the user. For example, when the amount to sell each stock is determined based on the weighting of each stock that constitutes an index, the maximum quantity that can be sold is determined according to the trading price of each stock. For example, since the quantity that can be sold for a stock is determined based on the selling amount according to the weighting of the stock and the trading price of the stock, the upper limit on the amount that the user can sell is also determined based on the number held by the user and the trading price of the stock.

[0362] Therefore, since the upper limit of the amount that a user can sell is determined according to the number of each stock that the user holds, the trading operation screen 2400 may display the upper limit of the amount that a user can sell when trading based on an index, or may invalidate the input of a selling amount that exceeds the upper limit of the amount that a user can sell (up to the upper limit of the amount that can be sold), or may allow the user to specify that they will sell at the upper limit of the amount that they can sell (for example, a button may be displayed that specifies that they will sell at the upper limit of the amount that they can sell).

[0363] The buy order operation unit 2420 is an operation member that accepts buy order operations for buying each stock that constitutes an index from the user.

[0364] The trading method designation section 2422 is an operation member that accepts designation of the allocation of the trading amount to each stock that constitutes the index when trading the name of the index.

[0365] In the illustrated example, the trading method designation unit 2422 accepts a designation as a "weighted trade" in which an amount designated by the user is allocated to each stock according to the weighting (%) of each stock that constitutes the index. Also, a designation as an "equal allocation trade" in which an amount designated by the user is allocated equally to each stock that constitutes the index is displayed as being able to be accepted, and the user can designate either a "weighted trade" or an "equal allocation trade."

[0366] The transaction record confirmation operation unit 2424 is an operation member that accepts an operation to confirm the transaction record of each user for the index.

[0367] In the illustrated example, the transaction record confirmation operation unit 2424 displays information about the user who placed an order for the index, information about the transaction amount for the order, etc., in response to a user operation.

[0368] The user's portfolio confirmation operation section 2426 is an operation member that accepts an operation to confirm the user's portfolio.

[0369] <Modification> The inventions described in the above embodiments may be combined with each other. (Modification of the first embodiment) In the above description of the embodiment, an example has been described in FIG. 19 etc. in which an object including information about a stock is displayed on the screen and the results of the user's stock evaluation are distributed depending on the direction of a swipe or flick operation. In addition, an object containing user information regarding whether or not a user will follow another user may be displayed on the screen, and the operation content regarding whether or not to follow another user may be assigned depending on the direction of the swipe or flick operation. For example, the server 20 presents information about other users to the user by displaying an object containing the information about the other users at a predetermined timing. The object displays information about the user, such as the user's score, portfolio, posted content, followers, and following, as described with reference to FIG. The server 20 displays the object on the screen of the terminal 10 and accepts an operation of "follow" or "don't follow" depending on the direction of the swipe or flick operation. For example, a "follow" operation may be accepted by swiping (flicking) the screen to the right, and an "don't follow" operation may be accepted by swiping (flicking) the screen to the left. The server 20 may present the user with the above object including information about other users the user has not yet followed, and accept a designation of follow or don't follow via a touch operation. By following each other, users can thereby encourage interaction, such as viewing each other's investment-related posts, and further encourage investment. Furthermore, for other users that a user is already following, an object containing information about the other users may be displayed in the same manner as above, and a touch operation to decide whether or not to follow the other users may be accepted. This provides each user with an opportunity to decide whether or not to continue following the other users, further optimizing the following and follower relationships of each user. The server 20 displays objects containing information on one or more other users one after another each time the user specifies whether to follow the other user by touch operation, thereby allowing the user to easily specify whether to follow the other user. The server 20 may present an object including information about other users to the user as described above and accept a designation as to whether or not to follow the user, and may set the following conditions as triggers. The trigger is when the user executes an application (when a new application is started, or when the terminal 10 returns from a sleep state). Triggered when the frequency, number of transactions, volume, or transaction amount of a user's transactions reaches a certain level Triggered when the frequency and number of user posts about transactions reaches a certain level Triggered by the number of other users a user follows or is followed by reaching a certain level The server 20 may extract candidates for other users for which a designation as to whether or not to follow is to be accepted as follows. Other users who trade the same stocks as the user with a certain frequency, number of times, or number of holdings. Follower Asset Score is above a certain level or other users who are in the top ranks - Your account balance is above a certain amount, or you are a member of another user listed above. Other users who post at a certain frequency and frequency Other users who have a certain number of followers or followings Other users who have made their portfolios public

[0370] (Modification of the second embodiment)

[0371] (1) A method for extracting stocks that make up an index according to the user's level of interest In the above second embodiment, an example has been described in which stocks constituting an index are extracted in accordance with the stock holding status of each user, and an index value is calculated. Stocks constituting an index may also be extracted in accordance with information on stocks that each user focuses on, and for example, the following may be done. Stocks may be extracted according to the volume of stock traded by each user in the service. For example, the server 20 may refer to the stock trading database 212 and extract stocks that are traded more frequently within a certain period (the larger the volume of trades by each user in the service) as stocks that constitute the index. The stocks constituting the index may be extracted according to the frequency with which stock information is included in posts by users on the service. For example, the server 20 may refer to the posting history database 213 and identify stocks included in posts by each user, and extract stocks that are frequently talked about by each user and posted, stocks that frequently receive responses, stocks included in posts with a high number of responses, etc., as stocks constituting the index. The stocks that make up the index may be extracted according to the track record of stock evaluations by users in the service. For example, the server 20 may refer to the stock evaluation database 214 and extract stocks that have been evaluated by users many times or frequently as stocks that make up the index. Here, the server 20 may extract stocks that make up the index according to the content of the evaluations of the stocks (for example, by placing emphasis on evaluations that the user is interested in, such as "buy" or "on watch list"). (2) Extraction method of stocks that make up the index according to sector In the above embodiment, an example has been described in which stocks constituting an index are extracted regardless of the sector of the stock.
