Description
本揭露是有關於一種基金追蹤系統、基金追蹤方法及圖案化使用者介面。 This disclosure relates to a fund tracking system, a fund tracking method and a graphical user interface.
共同基金的報酬取決於其持有風險性資產的報酬。如果我們能夠預判其持有風險性資產的未來趨勢,將有助於預測該基金的未來報酬。例如:OPEC宣布石油減產,往往有助於石油類相關指數上漲。因此,我們能夠預判那些大量持有石油資產的基金將會有一段漲幅。 A mutual fund's returns depend on the return on the risky assets it holds. If we can predict the future trend of its risky assets, it will help predict the future returns of the fund. For example: OPEC's announcement of oil production cuts often helps oil-related indexes rise. Therefore, we can predict that funds that hold large amounts of oil assets will have a period of growth.
然而,基金持有風險性資產是橫跨多個產業及多個市場,每種資產其持有比重不同,較困難就單一資產趨勢推測該基金未來趨勢。 However, the fund holds risky assets across multiple industries and markets, and each asset holds a different proportion. It is difficult to predict the future trend of the fund based on the trend of a single asset.
尤其是基金對外揭露的資訊甚少,僅有公布較大加權係數資產的公司及其加權係數、以國家別來分類的加權係數、以各產業別分類的加權係數等等綜合性資訊。此外,基金揭露週 期較長,持有資產訊息揭露的週期最短一個月,甚至有一季或者半年者。 In particular, funds disclose very little information to the outside world. They only publish comprehensive information such as companies with assets with larger weighting coefficients and their weighting coefficients, weighting coefficients classified by country, weighting coefficients classified by industry, etc. In addition, Fund Disclosure Week The period is longer, and the period for disclosing asset holding information is as short as one month, or even as long as a quarter or half a year.
因為資訊有限,導致無法使投資人有效地把資訊與市場做連結產生交易決策。 Due to limited information, investors cannot effectively connect the information with the market to make trading decisions.
本揭露係有關於一種基金追蹤系統、基金追蹤系統及圖案化使用者介面。 The present disclosure relates to a fund tracking system, a fund tracking system and a graphical user interface.
根據本揭露之一實施例,提出一種基金追蹤方法。基金追蹤方法用以對一目標基金進行追蹤。基金追蹤方法包括以下步驟。依據目標基金之一基金基準指數獲得數個指數股票型基金(Exchange Traded Fund,ETF)資產類別。依據此些ETF資產類別,獲得數個代表ETF。依據此些代表ETF,生成一模擬投資組合。驗證模擬投資組合是否滿足一驗證條件。若模擬投資組合滿足驗證條件,則輸出模擬投資組合。 According to an embodiment of the present disclosure, a fund tracking method is proposed. The fund tracking method is used to track a target fund. The fund tracking method includes the following steps. Several index stock fund (Exchange Traded Fund, ETF) asset classes are obtained based on the fund benchmark index of one of the target funds. Get several representative ETFs based on these ETF asset classes. Based on these representative ETFs, a simulated investment portfolio is generated. Verify whether the simulated investment portfolio satisfies a verification condition. If the simulated investment portfolio meets the verification conditions, the simulated investment portfolio is output.
根據本揭露之另一實施例,提出一種基金追蹤系統。基金追蹤系統用以對一目標基金進行追蹤。基金追蹤系統包括一選定單元及一生成單元。選定單元包括一資產類別選定器及一指數股票型基金(Exchange Traded Fund,ETF)選定器。資產類別選定器用以依據目標基金之一基金基準指數獲得數個ETF資產類別。ETF選定器用以依據此些ETF資產類別,獲得數個代表ETF。生成單元包括一組合器及一驗證器。組合器用以依據此些代表ETF,生成一模擬投資組合。驗證 器用以驗證模擬投資組合是否滿足一驗證條件。若模擬投資組合滿足驗證條件,則輸出模擬投資組合。 According to another embodiment of the present disclosure, a fund tracking system is provided. The fund tracking system is used to track a target fund. The fund tracking system includes a selection unit and a generation unit. The selection unit includes an asset class selector and an index stock fund (Exchange Traded Fund, ETF) selector. The asset class selector is used to obtain several ETF asset classes based on one of the target fund's fund benchmark indexes. The ETF selector is used to obtain several representative ETFs based on these ETF asset classes. The generation unit includes a combiner and a verifier. The combiner is used to generate a simulated portfolio based on these representative ETFs. Verify The device is used to verify whether the simulated investment portfolio meets a verification condition. If the simulated investment portfolio meets the verification conditions, the simulated investment portfolio is output.
根據本揭露之再一實施例,提出一種圖案化使用者介面。圖案化使用者介面用以供一使用者對一目標基金進行追蹤。圖案化使用者介面包括一設定按鈕及一基金預測結果按鈕。設定按鈕用以輸入目標基金。數個指數股票型基金(Exchange Traded Fund,ETF)資產類別係依據目標基金之一基金基準指數獲得。數個代表ETF係依據此些ETF資產類別獲得。一模擬投資組合係依據此些代表ETF生成。基金預測結果按鈕用以顯示模擬投資組合之一上漲期望值或一綜合趨勢。 According to yet another embodiment of the present disclosure, a patterned user interface is provided. The graphical user interface is used for a user to track a target fund. The graphical user interface includes a setting button and a fund prediction result button. The Set button is used to enter the target fund. Several index stock fund (Exchange Traded Fund, ETF) asset classes are obtained based on the fund benchmark index of one of the target funds. Several representative ETFs are obtained based on these ETF asset classes. A simulated portfolio is generated based on these representative ETFs.

指數股票型基金(Exchange Traded Fund,ETF)是由數個風險性資產所組成。相較於個別資產,ETF符合基金的組成特徵。此外,相較於基金,ETF的資產配置透明、交易資訊更新頻率相當的高(例如是每日更新)、並且低追蹤誤差的ETF可以直接代表其追蹤的指數。因此,在本實施例中,研究人員利用ETF來追蹤基金,以進一步預測基金的未來走向。 Index stock funds (Exchange Traded Fund, ETF) are composed of several risky assets. Compared with individual assets, ETFs conform to the composition characteristics of funds. In addition, compared with funds, ETFs have transparent asset allocation, fairly high trading information update frequency (for example, daily updates), and low tracking error ETFs can directly represent the index they track. Therefore, in this embodiment, researchers use ETFs to track funds to further predict the future direction of the fund.
請參照第1圖,其繪示根據一實施例之基金追蹤系統100之方塊圖。基金追蹤系統100例如是一伺服器主機、一電腦、一雲端運算中心或一智慧型手機。基金追蹤系統100包括一選定單元110、一生成單元120及一趨勢預測單元130。選定單元110、生成單元120及趨勢預測單元130例如是一電路、一晶片、一電路板、或儲存程式碼之儲存裝置。選定單元110包括資產類別選定器111及ETF選定器112。生成單元120包括一組合器121及一驗證器122。資產類別選定器111、ETF選定器112、組合器121及驗證器122例如是一電路、一晶片、一電路板、或儲存程式碼之儲存裝置。
本實施例之基金追蹤系統100透過選定單元110選定出數個代表ETF ECi(i=1,2,...)。生成單元120再根據這些代表ETF ECi(i=1,2,...)來生成模擬投資組合FS。有了模擬投資組合FS之後,即可準確地追蹤目標基金TF。進一步更可利用模擬投資組合FS來預測目標基金TF之趨勢。以下更搭配一流程圖詳細說明上述各項元件之運作。
Please refer to FIG. 1 , which illustrates a block diagram of a
請參照第1圖及第2圖,第2圖繪示根據一實施例之基金追蹤方法的流程圖。在步驟S110中,資產類別選定器111依據目標基金TF之一基金基準指數DX獲得數個ETF資產類別Ci(i=1,2,...)。ETF資產類別Ci例如是產業類別、區域類別、固定收入類別、匯率類別等,下表一亦有示例說明ETF資產類別Ci與基金基準指數DX之關係。 Please refer to Figure 1 and Figure 2. Figure 2 illustrates a flow chart of a fund tracking method according to an embodiment. In step S110, the asset class selector 111 obtains several ETF asset classes Ci (i=1, 2,...) based on one of the fund benchmark indexes DX of the target fund TF. ETF asset categories Ci are, for example, industry categories, regional categories, fixed income categories, exchange rate categories, etc. Table 1 below also has examples illustrating the relationship between ETF asset categories Ci and the fund benchmark index DX.
請參照第3圖,其示例說明資產類別選定器111執行步驟S110之一例。資產類別選定器111取得目標基金TF後,利用基金基準指數擷取程序(benchmark index extraction)P31從基金公開說明書或基金網站擷取到基金基準指數DX。舉例來說,股票型基金「富達基金-全球入息基金」的基金基準指數DX為「MSCI ACWI NR USD」;債券型基金「富達基金-美元債券基金」的基金基準指數DX為「ICE BofA US LC Corp&Govt TR USD」。基金基準指數DX對應到的是目標基金TF的投資目標及區域。兩檔不同的目標基金TF如果基金基準指數DX一樣,則兩檔目標基金TF的投資目標及區域一樣。 Please refer to Figure 3, which illustrates an example of the asset class selector 111 executing step S110. After obtaining the target fund TF, the asset class selector 111 uses the fund benchmark index extraction program (benchmark index extraction) P31 to retrieve the fund benchmark index DX from the fund prospectus or the fund website. For example, the fund benchmark index DX of the stock fund "Fidelity Fund-Global Income Fund" is "MSCI ACWI NR USD"; the fund benchmark index DX of the bond fund "Fidelity Fund-USD Bond Fund" is "ICE BofA US LC Corp&Govt TR USD". The fund benchmark index DX corresponds to the investment objectives and areas of the target fund TF. If the fund benchmark index DX of two different target fund TFs is the same, the investment objectives and areas of the two target fund TFs will be the same.
接著,在類別擷取程序(class extraction)P32中,利用一查找表(如基金基準指數與類別對應表TB)取得ETF資產類別Ci(i=1,2,...)。由於基金基準指數DX的數量有限,可以人工方式提供並維護。舉例來說,如下表一所示,其示例說明基金基準指數與類別對應表TB。不同的基金基準指數DX所對應到的ETF資產類別Ci(i=1,2,...)之數量可能不同。由於基金基準指數DX的變化有限,故可以輕鬆維護基金基準指數與類別對應表TB。 Next, in the class extraction program (class extraction) P32, a lookup table (such as the fund benchmark index and class correspondence table TB) is used to obtain the ETF asset class Ci (i=1,2,...). Since the number of fund benchmark index DX is limited, it can be provided and maintained manually. For example, as shown in Table 1 below, it illustrates the fund benchmark index and category correspondence table TB. Different fund benchmark indexes DX may correspond to different numbers of ETF asset classes Ci (i=1,2,...). Since the changes in the fund benchmark index DX are limited, the fund benchmark index and category correspondence table TB can be easily maintained.
然後,在第2圖之步驟S120中,ETF選定器112依據此些ETF資產類別Ci(i=1,2,...),獲得數個代表ETF ECi(i=1,2,...)。在此步驟中,所獲得之代表ETF EC1係為ETF資產類別C1之數個ETF的最佳者;所獲得之代表ETF EC2係為ETF資產類 別C2之數個ETF的最佳者;依此類推。最佳者之挑選則是依據一ETF評分資訊排名Rij來獲得各個代表ETF ECi(i=1,2,...)。評分資訊的內容例如是「字母等級/Fit值」。字母等級為有效性和可交易性部分(Efficiency and Tradability)的得分,字母等級可以客觀地衡量ETF的運行狀況以及買賣的容易程度。Fit值實質上是衡量ETF佔領更大市場的能力,可視投資者需求選擇。如想跟隨大盤,會選擇Fit值分數較高者;如不想與廣泛市場相同的,則選擇Fit值較低者。本實施例以選擇Fit值分數較高者為例。 Then, in step S120 in Figure 2, the ETF selector 112 obtains several representative ETFs ECi (i=1,2,...) based on these ETF asset categories Ci (i=1,2,...) ). In this step, the representative ETF EC1 obtained is the best of several ETFs of the ETF asset class C1; the representative ETF EC2 obtained is the ETF asset class The best of several ETFs in C2; and so on. The selection of the best one is based on an ETF rating information ranking Rij to obtain each representative ETF ECi (i=1,2,...). The content of the rating information is, for example, "letter grade/fit value". The letter grade is a score for the Efficiency and Tradability section. The letter grade can objectively measure the performance of the ETF and the ease of buying and selling. The Fit value essentially measures the ETF's ability to occupy a larger market and can be selected based on investor needs. If you want to follow the market, you will choose the one with a higher Fit value; if you don't want to be the same as the broader market, you will choose the one with a lower Fit value. This embodiment takes selecting the one with a higher Fit value as an example.
舉例來說,某三筆ETF的評分資訊例如是「A/85」、「B/72」、「B/85」。三筆ETF評分資訊進行比較時,先以字母等級進行排序(A優先於B,B優先於C,依此類推)。再以Fit值進行排序(數字大者優先)。故這三筆ETF之評分資訊的順序為「A/85」、「B/85」、「B/72」,其評分資訊排名Rij分別為1、2、3。 For example, the rating information of a certain three ETFs is "A/85", "B/72", and "B/85". When comparing three ETF score information, they are first sorted by letter grade (A takes precedence over B, B takes precedence over C, and so on). Then sort by the Fit value (the one with the larger number takes precedence). Therefore, the order of the scoring information of these three ETFs is "A/85", "B/85", and "B/72", and their scoring information rankings Rij are 1, 2, and 3 respectively.
請參照下表二,其示例說明依據評分資訊排名Rij針對11個ETF資產類別Ci(i=1,2,...)所獲得之11個代表ETF ECi(i=1,2,...)。 Please refer to Table 2 below, which illustrates the example of 11 representative ETF ECi (i=1,2,...) obtained based on the scoring information ranking Rij for 11 ETF asset classes Ci (i=1,2,...) ).
在一實施例中,除了直接以評分資訊排名Rij之最佳者來挑選代表ETF以外,亦可進一步參考被挑選次數SCij來進行選擇。舉例來說,被挑選到的某一代表ETF在後續合成模擬投資組合FS的過程中可能被判定不合適合而被移除。故在步驟S120挑選代表ETF時,則不適合一直去挑選經常被移除者。 In one embodiment, in addition to directly selecting the representative ETF based on the best rating information ranking Rij, the selection can also be made with further reference to the number of times SCij is selected. For example, a selected representative ETF may be judged to be unsuitable and removed in the subsequent process of synthesizing the simulated portfolio FS. Therefore, when selecting representative ETFs in step S120, it is not suitable to always select those that are frequently removed.
ETF選定器112可以利用下式(1)、(2)來挑選代表ETF ECi(i=1,2,...)。 The ETF selector 112 can select the representative ETF ECi (i=1,2,...) using the following equations (1) and (2).
在本文中,i指不同ETF資產類別,j指同一ETF資產類別中的不同ETF。第i個ETF資產類別Ci中第j個ETF具有評分資訊排名Rij、被挑選次數SCij、挑選機率加權係數Wij及挑選機率Pij。 In this article, i refers to different ETF asset classes and j refers to different ETFs within the same ETF asset class. The j-th ETF in the i-th ETF asset class Ci has a rating information ranking Rij, the number of selections SCij, a selection probability weighting coefficient Wij, and a selection probability Pij.
如第(1)式所示,評分資訊排名Rij越小,挑選機率加權係數Wij越大;被挑選次數SCij越小,挑選機率加權係數Wij越大。因此,評分資訊排名Rij越佳者且被挑選次數SCij越低者,越容易被挑選到。 As shown in equation (1), the smaller the rating information ranking Rij, the greater the selection probability weighting coefficient Wij; the smaller the number of selections SCij, the greater the selection probability weighting coefficient Wij. Therefore, the better the rating information ranking Rij and the lower the number of selections SCij, the easier it is to be selected.
接著,在第2圖之步驟S130中,組合器121依據此些代表ETF ECi(i=1,2,...),生成模擬投資組合FS。並且在第2圖之步驟S140中,驗證器122判斷模擬投資組合FS是否滿足一驗證條件。
Next, in step S130 in Figure 2, the
模擬投資組合FS係為這些代表ETF ECi(i=1,2,...)與加權係數WCi(i=1,2,...)的乘積合(即Σ i WC i * EC i )。請參照第4圖,其示例說明組合器121執行步驟S130且驗證器122執行步驟S140之一例。
The simulated investment portfolio FS is the product of these representative ETFs ECi (i=1,2,...) and the weighting coefficient WCi (i=1,2,...) (i.e. Σ i WC i * EC i ). Please refer to FIG. 4 , which illustrates an example in which the
組合器121取得代表ETF ECi(i=1,2,...)之後,可以在加權係數計算程序P41中依據迴歸模型(regression model)來計算出加權係數WCi(i=1,2,...)。迴歸模型例如是套索迴歸模型(lasso regression model)或節脊迴歸模型(Ridge Regression model)。組合器121在計算加權係數WCi(i=1,2,...)的過程中,必須滿足以下幾個限制條件:所有加權係數WCi(i=1,2,...)之和為1(即Σ i WC i =1)。並且任何加權係數WCi(i=1,2,...)皆大於或等於0(即WC i 10),代表沒有放空的情況。倘若組合器121在這些限制條件下無法計算出加權係數WCi(i=1,2,...),則輸出空值。
After the
然後,在加權係數確認程序P43中,組合器121確認加權係數WCi(i=1,2,...)是否皆大於一預定權重值。當某一加
權係數不大於預定權重值時,表示對應的代表ETF之代表性不足,而需要在刪除程序P44中予以刪除,並重新回至加權係數計算程序P41。
Then, in the weighting coefficient confirmation program P43, the
順利通過加權係數計算程序P41、加權係數確認程序P43後,則可進入驗證程序P45。 After successfully passing the weighting coefficient calculation procedure P41 and the weighting coefficient confirmation procedure P43, you can enter the verification procedure P45.
在驗證程序P45中,驗證器122驗證模擬投資組合FS是否滿足驗證條件。驗證條件係為模擬投資組合FS與目標基金TF之一報酬變化近似度小於一臨界值。驗證器122例如是利用柯爾莫哥洛夫-斯米爾諾夫檢驗(kolmogorov-smirnov test,K-S test)分析出報酬變化近似度。
In the verification program P45, the
請參照第5圖,其示例說明執行驗證程序P45之一例。如第5圖上側圖示所示,組合器121利用時間點T1~T2之資訊於時間點T2建立出模擬投資組合FS。接著,驗證器122即可於時間點T2~T3採集模擬投資組合FS之報酬變化與目標基金TF之報酬變化,並判斷兩者之近似度是否小於臨界值。通過驗證後,模擬投資組合FS即可用來進行時間點T4後的預測。
Please refer to Figure 5, which illustrates an example of executing the verification program P45. As shown in the upper diagram of Figure 5, the
此外,如第5圖下側圖示所示,若要進行時間點T8後的預測,可以於時間點T5~T6重新建立新的模擬投資組合FS’。倘若時間點T6建立出的模擬投資組合FS’能夠於時間點T6~T7通過驗證。模擬投資組合FS’即可用來進行時間點T8後的預測。 In addition, as shown in the lower side of Figure 5, if you want to make predictions after time point T8, you can re-create a new simulated investment portfolio FS’ at time points T5~T6. If the simulated investment portfolio FS’ established at time point T6 can pass the verification at time points T6~T7. The simulated investment portfolio FS’ can be used to make predictions after time point T8.
一般而言,目標基金TF在短時間內對相同產業類別的投資百分比變化不會太大。前後兩期(最短一個月),相同產業的投資百分比變化通常不會超過1%。因此,通常模擬投資組合FS可以維持一段時間的有效性。 Generally speaking, the investment percentage of target fund TF in the same industry category will not change much in a short period of time. In the two periods before and after (the shortest one month), the change in investment percentage in the same industry will usually not exceed 1%. Therefore, usually the simulated portfolio FS can maintain its effectiveness for a period of time.
如第4圖所示,若驗證器122驗證出模擬投資組合FS滿足驗證條件,則輸出模擬投資組合FS(如第2圖之步驟S140之結果為「是」時,進入步驟S150);若驗證器122驗證出模擬投資組合FS不滿足驗證條件,則輸出空值,並重新挑選代表ETF(如第2圖步驟S140之結果為「否」時,回至步驟S120)。
As shown in Figure 4, if the
在第2圖之步驟S150中,驗證器122輸出模擬投資組合FS至趨勢預測單元130。
In step S150 of FIG. 2 , the
在步驟S160中,趨勢預測單元130基於模擬投資組合FS,利用一深度學習模型預測目標基金TF之趨勢。請參照第6圖,其示例說明趨勢預測單元130執行步驟S160之一例。在市場觀點處理程序P61中,依據一市場觀點計算模擬投資組合FS之一上漲期望值UTV。
In step S160, the
請參照第7圖,其示例說明市場觀點處理程序P61之一例。在自然語言處理程序P71中,取得市場觀點TX,並根據財經情緒字典(Financial sentiment dictionary)SD計算出各種資產St(t=1,2,...)的資產看漲分數Dt(t=1,2,...)。t是指不同的資產。舉例來說,某一市場觀點TX為「麥格理預期金價有望逼近每盎司2000美元」。根據財經情緒字典SD可以分析出:「麥格理」為法人,「金價」為資產 St,「有望」為3分觀點,「逼近每盎司2000美元」為7分觀點。經過計算資產看漲分數Dt為5.0(即(3+7)/2)。每一資產St(t=1,2,...)都可透過同樣方式計算出資產看漲分數Dt(t=1,2,...)。 Please refer to Figure 7, which illustrates an example of the market opinion processing program P61. In the natural language processing program P71, the market view TX is obtained, and the asset bullish score Dt(t=1, 2,...). t refers to different assets. For example, a certain market view TX is "Macquarie expects gold prices to approach US$2,000 per ounce." According to the financial sentiment dictionary SD, it can be analyzed that: "Macquarie" is the legal person, and "Gold Price" is the asset. St, "hopeful" is a 3-point opinion, and "approaching US$2,000 per ounce" is a 7-point opinion. The asset bullish score Dt is calculated to be 5.0 (i.e. (3+7)/2). For each asset St(t=1,2,...), the asset call score Dt(t=1,2,...) can be calculated in the same way.
接著,在ETF上漲期望值計算程序P72中,依據各個代表ETF ECi(i=1,2,...)對於資產的配置比例Wit,計算出代表ETF ECi(i=1,2,...)之ETF看漲分數DCi(i=1,2,...)。ETF看漲分數DCi例如是依據下式(3)進行計算。 Next, in the ETF expected value calculation program P72, the representative ETF ECi (i=1,2,...) is calculated based on the asset allocation ratio Wit of each representative ETF ECi (i=1,2,...) The ETF bullish score DCi (i=1,2,...). The ETF call score DCi is calculated based on the following formula (3), for example.
DC i =Σ t W it * D t ...........................................................(3) DC i =Σ t W it * D t ........................................ .............(3)
然後,在基金上漲期望值計算程序P73中,依據ETF看漲分數DCi(i=1,2,...)計算模擬投資組合FS之上漲期望值UTV。上漲期望值UTV例如是依據下式(4)進行計算。 Then, in the fund's expected rise value calculation program P73, the expected rise value UTV of the simulated investment portfolio FS is calculated based on the ETF bullish score DCi (i=1,2,...). The expected increase value UTV is calculated based on the following formula (4), for example.
UTV=Σ i WC i * DC i .........................................................(4) UTV=Σ i WC i * DC i ..................................... ............(4)
回到第6圖,除了需要在市場觀點處理程序P61取得上漲期望值UTV以外,更需要在特徵擷取程序P62中取得價格嵌入特徵PEF與夏普值特徵SF。請參照第8圖,其示例說明執行特徵擷取程序P62之一例。在夏普值擷取程序P81中,係依據無風險利率R0擷取出夏普值特徵SF。在價格擷取程序P82中,係擷取過去一段時間的價格特徵PF。並且,經過特徵正規化程序P83,將價格特徵PF之數值移動到0以上的區間。再透過填0程序P84,將價格特徵PF填滿為某一預設長度的數值串列。接著,再利用嵌入特徵擷取程序(embedded feature extraction)P85取得價格嵌入特徵PEF。最後,則在特徵整合程序P86中將夏普值特徵SF與價格嵌入特徵PEF進行整合。在訓練 模型時,所有的基金是一起訓練的。因為每檔基金的代表ETF ECi的個數不一樣,造成訓練模型中的輸入有的較多(代表ETF ECi的個數多),有的較少(代表ETF ECi的個數少)。輸入數量不一致是無法進行深度學習的。所有輸入的數量必須要一致,才能取出一樣個數的特徴。因此,本實施例透過上述的填0程序P84,對於較少代表ETF ECi個數之基金把空缺的特徴補0,以進行對齊的動作。 Returning to Figure 6, in addition to obtaining the expected increase value UTV in the market view processing program P61, it is also necessary to obtain the price embedded feature PEF and Sharpe value feature SF in the feature extraction program P62. Please refer to Figure 8, which illustrates an example of executing the feature extraction program P62. In the Sharpe value extraction program P81, the Sharpe value characteristic SF is extracted based on the risk-free interest rate R0. In the price retrieval program P82, the price characteristics PF of the past period of time are retrieved. Furthermore, through the feature normalization program P83, the value of the price feature PF is moved to a range above 0. Then, through the 0-filling procedure P84, the price characteristic PF is filled with a numerical sequence of a certain preset length. Then, the embedded feature extraction program (embedded feature extraction) P85 is used to obtain the price embedded feature PEF. Finally, the Sharpe value feature SF and the price embedded feature PEF are integrated in the feature integration program P86. in training When building a model, all funds are trained together. Because the number of representative ETF ECi for each fund is different, some of the inputs in the training model are more (representing a greater number of ETF ECi) and some are less (representing a smaller number of ETF ECi). Deep learning cannot be performed if the number of inputs is inconsistent. All input quantities must be consistent in order to extract the same number of features. Therefore, in this embodiment, through the above-mentioned 0-filling procedure P84, the vacant characteristics of funds that represent a smaller number of ETF ECi are filled with 0 to perform the alignment operation.
回到第6圖,取得上漲期望值UTV、夏普值特徵SF與價格嵌入特徵PEF後,則可利用預測程序P63進行趨勢的預測。 Returning to Figure 6, after obtaining the expected increase value UTV, Sharpe value feature SF and price embedded feature PEF, the prediction program P63 can be used to predict the trend.
請參照第9圖,其示例說明執行預測程序P63之一例。在預測程序P63中,主要是利用深度學習模型MD預測目標基金TF之趨勢。上述上漲期望值UTV、夏普值特徵SF與價格嵌入特徵PEF可以輸入深度學習模型MD分別預測出短期趨勢FC1、中期趨勢FC2及長期趨勢FC3。接著,再將短期趨勢FC1、中期趨勢FC2、長期趨勢FC3、上漲期望值UTV、夏普值特徵SF與價格嵌入特徵PEF一起輸入至深度學習模型MD,以預測出綜合趨勢FC4。有了綜合趨勢FC4之後,即可據以給予是否買進的建議。 Please refer to Figure 9, which illustrates an example of executing the prediction program P63. In the prediction program P63, the deep learning model MD is mainly used to predict the trend of the target fund TF. The above-mentioned rising expected value UTV, Sharpe value feature SF and price embedding feature PEF can be input into the deep learning model MD to predict the short-term trend FC1, mid-term trend FC2 and long-term trend FC3 respectively. Then, the short-term trend FC1, mid-term trend FC2, long-term trend FC3, rising expectation value UTV, Sharpe value feature SF and price embedded feature PEF are input to the deep learning model MD to predict the comprehensive trend FC4. After having the comprehensive trend FC4, you can give suggestions on whether to buy or not.
除了上述實施方式以外,再計算出上漲期望值UTV時,亦可直接根據上漲期望值UTV給予是否買進的建議。 In addition to the above implementation methods, when the expected increase value UTV is calculated, a recommendation on whether to buy can also be given directly based on the expected increase value UTV.
透過上述實施例即可準確地追蹤目標基金TF,並進一步更可利用模擬投資組合FS來預測目標基金TF之趨勢。 Through the above embodiment, the target fund TF can be accurately tracked, and further the simulated investment portfolio FS can be used to predict the trend of the target fund TF.
此外,請參照第10圖,其示例說明根據一實施例之圖案化使用者介面900的示意圖。為了方便使用者直接在智慧型
手機、筆記型電腦、桌上型電腦進行操作,更可提供一圖案化使用者介面900來執行上述基金追蹤方法。圖案化使用者介面900包括一設定按鈕K1、一資產預測結果按鈕K2、一ETF預測結果按鈕K3及一基金預測結果按鈕K4。設定按鈕K1用以進入一視窗,以供使用者設定目標基金TF。資產預測結果按鈕K2用以顯示上述各種資產St(t=1,2,...)的資產看漲分數Dt(t=1,2,...)。ETF預測結果按鈕K3用以顯示上述代表ETF ECi(i=1,2,...)之ETF看漲分數DCi(i=1,2,...)。基金預測結果按鈕K4用以顯示上述模擬投資組合FS之上漲期望值UTV、或者是綜合趨勢FC4。
