  As described above, the analyst report created for another economic index that shows behavior similar to the attention interval XY that is focused on a certain economic index is displayed and output on the display device 24. The analyzed analyst report can be used as a reference when analyzing the behavior in the attention interval XY. As described above, the report output unit 210 reads out the analyst report associated with the date included in the similar section detected by the similar section detection unit 204 from the report storage unit 208 and displays and outputs it on the display device 24. In this example, the report output unit 210 reads from the report storage unit 208 the analyst report associated with the economic index detected by the similar section detection unit 204 and the date included in the similar section, and the report name thereof, and displays the display device 24. To display.

  Note that the report output unit 210 includes, for the time series data of a plurality of economic indicators stored in the time series data storage unit 206, the report name of the economic indicator input by the input device 22 among the plurality of economic indicators. It may be configured to display the report name of other economic indicators in a different display format, for example, the color of the text of the report name may be different, the thickness of the text of the report name may be different, The background color of the report name character may be a different background color. Thereby, when the report name of the economic index different from the economic index input by the user to the input device 22 is displayed, the report name of the other economic index can be presented to the user in an easy-to-understand manner. When the report names of a plurality of economic indicators including the input economic indicator are displayed, the difference of the economic indicators in the plurality of report names can be presented to the user in an easily understandable manner by the display format. As a first example, when the similar section detection unit 204 detects identification information of a plurality of economic indicators as economic indicators having similar sections having similar behaviors, the user inputs the identification information of the plurality of economic indicators. The identification information of the economic index is given a flag indicating that it is the same as the economic index input by the user, but the identification information different from the identification information of the economic index input by the user among the identification information of the plurality of economic indexes Is attached with a flag indicating that it is different from the economic index input by the user, and the report output unit 210 changes the display format of the report names of the plurality of economic indices according to the flag given to the identification information of the economic index You may do it. As a second example, the report output unit 210 is provided with the identification information of the economic index input by the user from the attention interval input unit 202 and holds the identification information of the economic index, and the similar interval detection unit 204 has similar behavior. When identification information of multiple economic indicators is detected as an economic indicator having similar sections, the identification information of the plurality of economic indicators is compared with the identification information of the retained economic indicators, and the comparison is made based on the comparison result The display format of the report name for the target economic indicator may be changed, and the identification information of the economic indicator input by the user among the identification information of the plurality of economic indicators is the same as the economic indicator input by the user On the other hand, the identification information different from the identification information of the economic index input by the user among the identification information of the plurality of economic indicators is different from the economic index input by the user. That impart effect flag holds, the report output section 210 may change the display format in accordance with the granted flag to the identification information of economic indicators for the report name of the plurality of economic indicators.

FIG. 6B shows frequency components of the behavior of the time series data of the economic index A in the attention section XY shown in FIG. The similar section detection unit 204 in the present embodiment performs a Fourier transform on the behavior of the time series data, and determines whether the behaviors of the two sections are similar based on the frequency and phase obtained by the Fourier transform. To do. As an example, the similar section detection unit 204 may be configured to perform a process of performing discrete fast Fourier transform (DFFT) on time series data.

First, the similar section detection unit 204 performs Fourier transform processing on the behavior of the time series data of the economic index A in the attention section XY, and the reciprocal of the attention period input to the input screen of the display device 24 via the input device 22. A process of extracting a frequency component included in a frequency range from a lower limit frequency f _{1 including a} certain frequency of interest f ₀ to an upper limit frequency f _h is performed. Incidentally, similar section detecting unit 204 may store information of a preset lower limit frequency f _l and the upper limit frequency f _h in the internal storage device, in the example shown in FIG. 6 (b), the lower limit frequency f _l is noted The frequency f ₀ is 0.8 times, and the upper limit frequency f _h is set to 1.2 times the frequency of interest f ₀ . Next, the similar section detection unit 204 extracts the frequency component having the maximum intensity from the frequency components included in the frequency range from the lower limit frequency f ₁ to the upper limit frequency f _h . In this example, the intensity _{I a1} frequency _{f a1} is smaller than the intensity _{I a2} frequency _{f a2,} similar section detecting unit 204 extracts the frequency _{f a2} as the frequency component of the maximum intensity. Incidentally, in FIG. 6 (b), for ease of illustration, among the frequency components of the Fourier transform, the frequency components of from the lower limit frequency f _l to an upper limit frequency f _h is exemplified.

FIG. 7A shows an example of the behavior of time series data in another economic index B. FIG.

The similar interval detection unit 204 performs Fourier transform processing on the behavior of the time series data of other economic indicators B included in the interval having the same length as the attention interval XY in the time series data of other economic indicators B Then, frequency components included in the frequency range from the lower limit frequency f ₁ to the upper limit frequency f _h are extracted with the attention frequency f ₀ as the center. Then, the similar segment detection unit 204, among the frequency components included in the frequency range from the lower frequency f _l to an upper limit frequency f _h, extracts a frequency component of the maximum intensity. In this example, as shown in FIG. 7 (b) and FIG. 7 (c), the similarity section detecting unit 204 extracts the frequency _{f b1} as a frequency component of the maximum intensity of the interval _{T 1,} the maximum intensity of the section _{T 2} The frequency f _b2 is extracted as the frequency component of. In FIG. 7B and FIG. 7C, frequency components from the lower limit frequency _fl to the upper limit frequency f _h are illustrated among the frequency components after Fourier transform in order to simplify the drawing. .

FIG. 8 is an explanatory diagram for explaining an example of a mode in which the phases of the economic index A to be analyzed and the other economic indices B are compared. Curve A in FIG. 8 corresponds to the waveform of frequency component f _a2 , curve B ₁ corresponds to the waveform of frequency component f _b1 , and curve B ₂ corresponds to the waveform of frequency component f _b2 . The similar section detection unit 204 extracts and compares the amplitude and phase information of the frequency component f _a2 included in the time series data of the economic index A and the frequency component f _b2 included in the time series data of the other economic index B. To do. In the similar section detection unit 204 in the present embodiment, a peak whose convexity is above the frequency component f _b2 included in the time series data of the other economic index B is the frequency component f _a2 included in the time series data of the economic index A. The time series data behavior of the economic indicator A and other economic indicators B when the peak is in a predetermined range of a peak protruding above the frequency component f _a2 , for example, within a range of ± π / 4, with reference to the phase of It is determined that the behavior of the time series data is similar. Note that the similar section detection unit 204 stores information indicating a predetermined range, for example, ± π / 4, in advance in the internal storage device as a range for determining the similarity of the phases.

In the example shown in FIG. 8, the peak P _b2 that protrudes above the frequency component f _b2 included in the time series data of the other economic index B is the phase of the frequency component f _a2 included in the time series data of the economic index A. the basis, is within the range of ± [pi / 4 of the peak P _a which is convex on the frequency components f _a2. Meanwhile, the peak P _b1 that is convex on the frequency components f _b1 contained in the time-series data of other economic indicators B, is outside the ± [pi / 4 of the peak P _a. Thus, similarity section detector 204, the behavior in the interval T ₂ of the time-series data of other economic indicators B, are judged to be similar to the behavior of the time series data of economic A in the target segment XY, interval T ₂ is detected as a similar interval.

For example, the similar section detection unit 204 reads the storage information of each economic index record stored in the time series data storage unit 206, extracts time series data and economic index identification information from the storage information, and extracts the time information. It is good also as a structure which performs the Fourier-transform process of series data, and matches the process result with the identification information of the said economic parameter | index, and hold | maintains it. Then, the similar section detection unit 204 calculates a maximum intensity frequency component among frequency components within a range of, for example, 0.8 to 1.2 times the frequency of interest, and calculates a phase in the frequency component ( S304). Then, the similar section detection unit 204 uses the phase of the frequency component of the maximum intensity included in the time series data of the economic index A as a reference, and the peak that protrudes above the time series data of the other economic index B is the economic index. The time series data of economic index A and the time series data of other economic indices B are determined by determining whether they are within the range of ± π / 4 of the peak that protrudes upward from the time series data of A It is determined whether or not the behavior is similar (S306). When the behavior of the time series data of the economic indicator A and the behavior of the time series data of the other economic indicator B are not similar (S306: No), the similar section detection unit 204 performs the processing for all the sections of the other economic indicators. It is determined whether or not similarities are compared (S314).

  When the behavior of the time series data of the economic indicator A and the behavior of the time series data of the other economic indicator B are similar (S306: Yes), the similar section detection unit 204 and the other information The identification information of the economic indicator B is output to the report output unit 210, and the report output unit 210 stores an analyst report related to the other economic indicator B associated with the date included in the comparison section (similar section). Extracted from the unit 208 (S308). For example, the report output unit 210 includes the target section field storing the section information including the similar section and the target among the records storing the identification information of the other economic index B in the economic index field in the report storage unit 208. The storage information such as the report name field and the important section field including the analyst report content data associated with the section field may be read and held. Then, the report output unit 210 determines whether or not the importance period of the analyst report extracted from the importance section field matches the attention period input from the user to the attention section input unit 202 (S310). When the importance period of the extracted analyst report does not match the attention period input by the user (S310: No), has the similar section detection unit 204 compared similarities for all sections of other economic indicators? It is determined whether or not (S314).

  When the importance period of the extracted analyst report matches the attention period input by the user (S310: Yes), information indicating the report name of the extracted analyst report is held (S312). Next, the similar section detection unit 204 determines whether or not similarities have been compared for all sections of other economic indicators (S314). When similarities are not compared for all sections of other economic indicators (S314: No), the similar interval detecting unit 204 shifts the comparison interval by a predetermined amount (S316), and the other economic indicators in the shifted comparison interval The time-series data waveform is subjected to Fourier transform processing (S302). Here, the predetermined amount may be, for example, a time unit of time-series data (one day in the example of the stock price shown in FIG. 2), or a section having the same length as the section of interest (shown in FIG. 4). January may be used in the attention section.

  When similarities are compared for all the sections of other economic indicators (S314: Yes), the similar section detecting unit 204 determines similarity to all other economic indicators stored in the time-series data storage unit 206. It is determined whether or not (S318). When similarity is not determined for all other economic indicators stored in the time-series data storage unit 206 (S318: No), the similar section detection unit 204 changes other economic indicators to be compared. Then, the waveform of the time series data of other economic indicators in the comparison section is subjected to Fourier transform processing (S302). For example, serial numbers may be assigned to records in the time-series data storage unit 206, and the economic index to be compared may be changed by comparing the time-series data in the records in the order of the serial numbers. The serial number may be assigned only to the plurality of records storing the time series data of the plurality of economic indicators with respect to the time series data of the plurality of economic indicators stored in the database. The similarity section detection unit 204 is a signal indicating that the similarity determination process is completed when similarity is determined for all other economic indicators stored in the time-series data storage unit 206 (S318: Yes). The determination processing end signal is output to the report output unit 210. Based on the similarity determination processing end signal, the report output unit 210 displays the retained report name on the display device 24 (S322), and the presentation shown in step S300. The processing operation of the apparatus main body 20 ends. In addition, it is good also as a structure which hold | maintains the content data of the analyst report with the report name, and displays the content of the analyst report with the report name on the display device 24. The report name is displayed on the display device 24 and the report name is clicked. In such a case, an analyst report having the report name may be displayed and output when the report name is displayed. When the report name is clicked on the display device 24, the analyst corresponding to the report name from the report storage unit 208 is clicked. The report content data may be read out and displayed.

  FIG. 13A shows an example of the frequency component of the economic index A to be analyzed. FIG. 13B shows an example of frequency components of another economic index B. In FIG. 13, in order to simplify the explanation, some of the frequency components of the economic index A and the other economic index B are shown. In the embodiment shown in FIG. 1 to FIG. 12, the similar section detection unit 204 is similar based on whether the phase is within a predetermined range in the vicinity of the Fourier transform frequency corresponding to the period of interest input from the user. Although the determination is made, the form of determining the similarity is not limited to this. As another form, as shown in FIGS. 13A and 13B, the similar section detection unit 204 may determine that a plurality of characteristic frequency components are similar when the phases are close to each other. Good.

  In the example shown in FIG. 13A and FIG. 13B, the similar interval detection unit 204 includes a plurality of characteristic frequencies among the frequency components of the time series data of the economic index A included in the attention interval XY. The frequency components having the maximum intensity in the range of, for example, 0.8 to 1.2 times the frequency corresponding to the short-term, middle-term, and long-term cycles are extracted. In addition, the similar section detection unit 204, for a section having the same length as the section of interest XY, among the frequency components of the time series data of other economic indicators B included in the section, the short-term, middle-term, and long-term cycles For example, frequency components with the maximum intensity in the range of 0.8 to 1.2 times the frequency of interest corresponding to are extracted.

In the example shown in FIG. 13 (a), the similarity section detector 204, a frequency component of economic A included in the target segment _XY, extracted f _{al, f am,} and _{f ah,} respectively. The frequency _fal is extracted as the frequency component of the maximum intensity within the range of 0.8 to 1.2 times the frequency corresponding to the long period, and 0.8 to 1. The frequency f _am is extracted as the frequency component with the maximum intensity within the range of twice, and the frequency f is extracted as the frequency component with the maximum intensity within the range of 0.8 to 1.2 times the frequency corresponding to the short period. Extract _ah . In the example shown in FIG. 13B, f _bl , f _bm , and f _bh are used as frequency components of other economic indicators B included in the section having the same length as the target section XY. Extract each one. The frequency f _bl is extracted as a frequency component having the maximum intensity within the range of 0.8 to 1.2 times the frequency corresponding to the long period, and 0.8 to 1. The frequency f _bm is extracted as the frequency component with the maximum intensity within the range of twice, and the frequency f is used as the frequency component with the maximum intensity within the range of 0.8 to 1.2 times the frequency corresponding to the short period. _bh is extracted. In this example shown in FIG. 13, the frequency components corresponding to the long-term, medium-term, and short-term cycles are shown as f ₁ , f _m , and f _h , respectively, and the long-term frequency f ₁ <the mid-term frequency f _m < and it has a short-term frequency _{f h.} The short term may be, for example, a cycle of one week, one month, or quarter, the middle term may be, for example, a cycle of about one year to two years, and the long term is, for example, a cycle of two years or more. As an example, the cycle may be three years or more.

FIG. 14 (a), an example shown in FIG. 13 (a) and 13 (b), the time-series waveform A _l and other economic indicators B of the time-series data of the economic A in the frequency component corresponding to the long-term A waveform B _l of data is shown, the waveform A _l corresponds to the long-term frequency f _l , and the waveform B _l corresponds to the frequency f _bl . FIG. 14 (b), an example shown in FIG. 13 (a) and 13 (b), the time-series waveform A _m and other economic indicators B of the time-series data of the economic A in the frequency component corresponding to the medium-term shows a waveform _{B m} of the data waveform _{a m} corresponds to the medium-term frequency _{f m,} the waveform _{B m} corresponds to the frequency _{f bm.} FIG. 14 (c), an example shown in FIG. 13 (a) and 13 (b), the time-series waveform A _h and other economic indicators B of the time-series data of the economic A in the frequency component corresponding to the short-term shows the waveform _{B h} of the data waveform _{a h} corresponds to the short-term frequency _{f h,} waveform _{B h} corresponds to the frequency _{f bh.}

  In this example, the similar section detection unit 204 uses the phase of the frequency component included in the time series data of the economic index A as a reference for the peak that is convex upward in the time series data of the other economic index B. By determining whether or not the peak is upwardly convex in the time series data, for example, within a range of ± π / 4, for example, the short-term, middle-term, and other economic indicators A and B It is determined whether the long-term waveforms are similar. Here, the similar section detection unit 204 performs the behavior of the time series data of the economic index A and the time series data of the other economic index B when the waveforms corresponding to the short term, the medium term, and the long term are all similar. It is determined that the behavior of is similar. Thereby, it is possible to extract an analyst report relating to another economic index having a behavior more similar to time series data of the economic index to be analyzed.

In the example shown in FIG. 14 (a), the peak _{P bl} that is convex on the waveform _{B l,} waveform _A relative to the phase of _l, the peak _{P al} ± _π / 4 of which is convex on the waveform _{A l} It is in the range. Further, in the example shown in FIG. 14 (b), a peak _{P bm} that is convex on the waveform _{B m,} based on the phase of the waveform _{A m,} waveform _A peak _{P am} ± of π which is convex on the _m Within the range of / 4. On the other hand, in the example shown in FIG. 14 (c), the peak _{P bh} which is convex on the waveform _{B h,} based on the phase of the waveform _{A h,} ± peak _{P ah} that is convex on the waveform _{A h} [pi Not within the range of / 4. In this case, the similar section detection unit 204 determines that the behavior of the time series data of the economic index A and the behavior of the time series data of the other economic index B are not similar for the section.

  In this example, the similar section detection unit 204 is similar in waveform of frequency components corresponding to each of the short-term, medium-term, and long-term, and the behavior of the time-series data of the economic index A and the time of other economic indices B When it is determined that the behavior of the series data is similar, the report output unit 210 extracts the analyst report associated with other economic indicators and dates included in the similar section from the report storage unit 208, and extracts Among the analyzed analyst reports, the display device 24 displays a report in which the importance period that the analyst report emphasizes matches the attention period input by the user.

In addition, the similar section detection unit 204 in the embodiment shown in FIGS. 1 to 12 has the maximum intensity among the frequency components included in the frequency range from the lower limit frequency _fl to the upper limit frequency f _{h in} order to extract the similar section. Although a frequency component is extracted, the form which extracts a frequency component is not restricted to this. In another embodiment, the similar section detection unit 204 has a predetermined number in order from the highest in intensity among the frequency components included in the frequency range from the lower limit frequency f ₁ to the upper limit frequency f _h around the target frequency f _0. It is good also as a structure which extracts (for example, the preset plurality). As yet another example, the similar section detection unit 204 has a frequency having an intensity greater than or equal to a predetermined value among frequency components included in a frequency range from the lower limit frequency f ₁ to the upper limit frequency f _{h with the target} frequency f ₀ as the center. It is good also as a structure which extracts all the components.

  In order to extract the phase similarity in the similar section, the similar section detection unit 204 has a time series data peak of another economic index B within a range of ± π / 4 of the peak of the time series data of the economic index A. Although it is determined whether there is, the form which determines the similarity of a phase is not restricted to this. As another form, the similar interval detection unit 204 has ± π / 4 of a peak that is convex on the time series data of the other economic index B and a peak that is convex on the time series data of the economic index A. It may be determined whether it is in a predetermined range narrower than the range, or it may be determined whether it is in a predetermined range wider than the range of ± π / 4.

  Further, the similar section detection unit 204 compares the phase of the frequency component in the vicinity of the frequency of interest using Fourier transform, so that the behavior of the time series data of the economic index A and the behavior of the time series data of the other economic index B However, the form of determining similarity is not limited to this. As another form, the similar section detection unit 204 may be configured by a neural network, and as shown in Patent Document 1, the similar section detection unit 204 learned using the back propagation learning method may determine similarity. In this case, for example, an expert related to investment of securities causes the similar interval detection unit 204 to learn the waveform of the similar economic indicator and the waveform of the economic indicator that is not similar, and the similar interval after learning. The detection unit 204 may be configured to determine the similarity between two waveforms.

  Moreover, although the said similar area detection part 204 detects a similar area about the other economic parameter | index different from the economic index of analysis object, the form which extracts a similar area is not restricted to this. As another form, the similar section detection unit 204 may be configured to detect, as a similar section, a section having a behavior similar to the target section XY for the same economic index as the analysis target economic index. May be configured to detect, as a similar section, a section having a behavior similar to the attention section XY in the analysis target economic index for a plurality of economic indices stored in the time-series data storage unit 206. In this case, the similar section detection unit 204 may be configured to detect a section including a part of the date included in the target section XY as a similar section, or detect a section that does not include the target section XY as a similar section. It is good also as a structure.

  The report storage unit 208 in the embodiment shown in FIGS. 1 to 14 also stores the contents of the analyst report in association with the report name, but the storage form of the analyst report is not limited to this. As another form, the report storage unit 208 of the presentation apparatus main body 20 stores only the report name among the report name and the analyst report, and an external database connected to the presentation apparatus main body 20 stores information indicating the report name. The contents data of the analyst report may be stored in association with each other so that the analyst report can be read from the external database.

  Further, the report storage unit 208 stores the report in association with the importance period emphasized in the analyst report, and the report output unit 210 matches the importance period with the attention period by the user's input. The form of outputting the analyst report is not limited to this. As another form, the report storage unit 208 may not store information about the importance period, and the report output unit 210 may output an analyst report for dates included in the similar section.
