Description
本發明係關於一種投資組合的估測方法,尤指一種類效率配置估測投資組合的方法,及能夠執行該方法的非暫態電腦可讀取記錄媒體。The present invention relates to a method for estimating an investment portfolio, in particular to a method for estimating an investment portfolio with efficiency allocation, and a non-transitory computer-readable recording medium capable of executing the method.
習知投資組合的效率配置,在於一投資組合包含多個資產(例如股票、債券…),假定這多個資產的投資比重的總和為1(且不以做空為操作),透過均異最適化(Mean-Variance Optimization)在多個投資組合中找出相同的預期報酬率且風險最小的投資組合,找出的每一個投資組合都有以下兩個特性:1.預期報酬率固定的情況下,使風險(標準差)降到最低。2.在風險(標準差)固定下,能使預期報酬率達到最高。The efficient allocation of conventional investment portfolios lies in that a portfolio contains multiple assets (such as stocks, bonds...), assuming that the sum of the investment proportions of these multiple assets is 1 (and does not use short-selling as an operation), through mean-difference optimization (Mean-Variance Optimization) Find the same expected rate of return and the least risky investment portfolio among multiple investment portfolios. Each investment portfolio found has the following two characteristics: 1. When the expected rate of return is fixed, Minimize risk (standard deviation). 2. With the risk (standard deviation) fixed, the expected rate of return can be maximized.
然而,所述均異最適化的效率配置,其所獲得各資產的比重可以不是整數(即帶有小數點的奇零數),實務上導致所估測的投資組合有投資金額不符合交易時的遞增金額的交易限制,因而無法將效率配置的投資組合直接投入交易市場中進行申購。However, in the above-mentioned homogenous optimal efficiency allocation, the proportion of each asset obtained may not be an integer (that is, an odd number with a decimal point), which in practice causes the investment amount of the estimated investment portfolio to be inconsistent with the transaction amount. There are trading restrictions on incremental amounts, so it is not possible to directly put an efficient allocation of investment portfolios into the trading market for subscription.
此外,由於所述均異最適化的演算過程複雜,故其系統的軟硬體也要符合高規格才能順暢執行。In addition, due to the complexity of the calculation process of the homogeneous optimization, the software and hardware of the system must meet high specifications in order to perform smoothly.
因此,如何解決上述習知效率配置的問題,即為本發明的重點所在。Therefore, how to solve the above-mentioned problem of conventional efficiency allocation is the key point of the present invention.

本發明提供一種類效率配置估測投資組合的方法100,其係由一電子裝置(圖中未示)以多個可執行碼所執行,並請參考圖1,所述方法100包括限制條件設定101、投資組合設定102、產生預期報酬資料103、集合104、計算斜率105、迴圈運算106,以及類效率配置107之步驟執行,其中:The present invention provides a
所述限制條件設定101之步驟,為挑選欲投資的多個資產,並對各該資產設定一符合金額遞增單位的限制條件。所述資產,可以是基金、股票或債券,但不以此為限。所述金額遞增單位,係所述資產之投資金額遞增的金額單位,不需要再經過換算或處理(例如四捨五入,或無條件捨去法等整數化處理),而能夠直接投入市場申購的金額。於本實施例中,欲投資的多個資產,係挑選如表1所示之基金A、基金B以及基金C之三筆基金,但本發明不以此述的基金及為三筆所限。
於一實施例中,該投資金額為各該投資組合內各該資產的一投入金額上限、一投入金額下限,以及一遞增金額。於一實施例中,該投入金額上限,是由一輸入介面之輸入而設定;該投入金額下限與該遞增金額,係依各該資產所知的申購限制及交易限制(例如證券交易單位所公告的限制)而自動帶出。所述投入金額上限,用於決定所產生的各該投資組合中的各資產欲投入交易的最高金額(對應各資產所佔的權重)。In one embodiment, the investment amount is an upper limit of investment amount, a lower limit of investment amount, and an incremental amount of each asset in each investment portfolio. In one embodiment, the upper limit of the investment amount is set by an input interface; the lower limit of the investment amount and the incremental amount are based on the subscription restrictions and transaction restrictions known to each asset (for example, announced by a stock exchange company) limit) and automatically brought out. The upper limit of the investment amount is used to determine the maximum amount to be invested in the transaction for each asset in each of the generated investment portfolios (corresponding to the weight of each asset).
所述投資組合設定102之步驟,為以若干該資產設定一投資組合,該投資組合包括該若干資產的投資金額,各該資產的投資金額設定為符合該限制條件。舉例來說,如表1所示的投資組合為基金A、基金B以及基金C等三檔基金的組合,該投資金額包括投入金額上限皆為5000元(新台幣,下同)、投入金額下限皆為1000元,且遞增金額以1000元(仟元)為單位,而此遞增金額的不同,用以產生滿足所述投入金額下限與投入金額上限的區間之中,包括基金A、基金B及基金C個的多種投資組合,例如一種投資組合中,基金A、基金B及基金C的投入金額分別設為1000元、5000元、3000元,此時投資總額為9000元,以此類推(併參表5的組別1)。The step of setting
所述產生預期報酬資料103之步驟,為在該投資組合中,該若干資產以個別的投資金額對應自一資料庫擷取的一歷史報酬資料以產生一預期報酬資料,所述資料庫可以是雲端伺服器,或所述電子裝置之本機伺服器。The step of generating expected
於一實施例中,該預期報酬資料如表2所示,包括一預估年化標準差、一預估年化夏普值,以及一預估年化報酬率,其中的預估年化夏普值是依據對應的預估年化標準差和預估年化報酬率所計算獲得,計算過程並考慮無風險利率,於此實施例中預設為1.5%(計算公式:夏普值=(報酬率-無風險利率)/標準差)。於此步驟中,並以該若干資產個別的投資金額佔投資總額的比例計算出投資權重。In one embodiment, the expected return data is shown in Table 2, including an estimated annualized standard deviation, an estimated annualized Sharpe value, and an estimated annualized rate of return, wherein the estimated annualized Sharpe value It is calculated based on the corresponding estimated annualized standard deviation and estimated annualized rate of return. The calculation process takes into account the risk-free interest rate, which is preset at 1.5% in this example (calculation formula: Sharpe value = (rate of return - risk-free rate)/standard deviation). In this step, the investment weight is calculated based on the ratio of the individual investment amount of the certain assets to the total investment.
承前例,基金A、基金B及基金C的投資總額為9000元,而基金A、基金B及基金C的投資權重可經計算為11.11%、55.56%、33.33%,所計算出的預估年化標準差為7.323、預估年化報酬率為11.781、預估年化夏普值為1.404 (併參表2的組別1)。
於一實施例中,該歷史報酬資料是從該資料庫在上市時間重疊的同一時間段中,擷取各該資產個別對應的一歷史報酬率所獲得。如表1所示,所述上市時間重疊的同一時間段,係以2021/1/1~2021/12/31為資料計算區間,但不以此例的時間段為限,所述同一時間段可以更長或更短,只要上市時間重疊即可。又如表3所示,該歷史報酬資料包括基金A、基金B以及基金C的歷史日報酬率,但本發明不以此為限。
再如表4所示,基金A、基金B以及基金C所屬的歷史報酬資料,依據個別歷史日報酬率(如表3所示),更進一步包括報酬率、標準差、年化報酬率和年化標準差。
所述隨機產生集合104之步驟,為透過遞增金額的變化,而重覆執行該投資組合設定之步驟,隨機產生包括多個該投資組合的一集合。於一實施例中,是以電腦利用應用程式進行所述多個該投資組合的隨機產生,但本發明不以此為限。如表5所示,為隨機產生包括組別1-20共20組投資組合的集合,其中各投資組合的基金A、基金B以及基金C,皆符合前述投入金額上限(5000元)和投入金額下限(1000元),且遞增金額以1000元為單位的條件。
所述計算斜率105之步驟,係按該多個投資組合的預估年化標準差進行大小的排序,以所述預估年化標準差符合一第一條件者的投資組合為一初始基準點(標示如圖2座標中的(X1,Y1))。所述符合該第一條件的投資組合,於一實施例中,可以是在該多個投資組合中,所述預估年化標準差最低的投資組合,例如表2中組別12的投資組合,其「預估年化標準差」為2.266而於所在的集合中為最低者。The step of calculating the
承上,接著再依其餘投資組合的預估年化報酬率與預估年化標準差,與該初始基準點對應之預估年化報酬率與預估年化標準差計算出的斜率,再對各該斜率進行大小的排序,以從該多個投資組合中獲得所述斜率最高者,符合一第二條件,例如圖2之座標中,標示為(X2,Y2)所屬之投資組合,其組別12的斜率1.963為最高(併參表6之當前組別12的當前預估年化標準差2.266、當前預估年化報酬率5.130,以及當前組別的斜率1.963)。Carrying on from the above, and then based on the estimated annualized rate of return and estimated annualized standard deviation of the rest of the investment portfolio, the slope calculated from the estimated annualized rate of return and estimated annualized standard deviation corresponding to the initial benchmark point, and then Sorting the magnitude of each of the slopes, so as to obtain the highest slope from the plurality of investment portfolios, which meets a second condition, for example, in the coordinates of Figure 2, the investment portfolio marked as (X2, Y2) belongs to it. Group 12 has the highest slope of 1.963 (see Table 6 for the current estimated annualized standard deviation of 2.266, the current estimated annualized rate of return of 5.130, and the current group's slope of 1.963).
所述迴圈運算106之步驟,為該多個投資組合中,以斜率高於該第二條件的投資組合為一更新基準點(以此更新基準點取代該初始基準點而為新的基準點),並剔除報酬率較低者以更新該集合,再回到該計算斜率之步驟,以獲得下一個斜率最高的投資組合條件。所述符合該第二條件者,除上述所述斜率為最高的投資組合,進一步也可以是該預估年化標準差低於所述斜率符合該第二條件者,以及該預估年化報酬率高於所述斜率符合該第二條件者,為所述報酬率較低者,以從該集合中剔除。所述「當前」,係指作為比較基礎之該初始基準點或該更新基準點所對應之組別、預估年化標準差、預估年化報酬率。The step of the
舉例來說,如以表6所示,根據組別1-20的投資組合,共進行了五次迴圈運算106之步驟,結果分別於表6中以前緣線的點編號1~5表示。前緣線的點編號1,是以組別12有最小預估年化標準差而作為初始基準點,再與其餘組別進行斜率的比較,其中以組別20有最大斜率1.963。接著,剔除組別1~19中,所述預估年化標準差與所述預估年化報酬率皆低於組別20者(即剔除組別6、組別12、組別15),改以組別20有最大斜率而為第一次的更新基準點,再與剔除後的其餘組別進行斜率的比較,以此類推,獲得以組別11有最大斜率而為第二次的更新基準點、以組別1有最大斜率而為第三次的更新基準點,以及以組別16有最大斜率而為第四次的更新基準點,藉此獲得組別12、組別20、組別11、組別1,以及組別16等五個前緣線的點編號1~5。
所述類效率配置107之步驟,為以該集合中的預估年化夏普值符合一估測條件的投資組合,估測為類效率配置者。於一實施例中,在該類效率配置之步驟中,將該初始基準點以及至少一該更新基準點所對應的斜率進行高低的排序,並以其中的預估年化夏普值最高者,視為符合該估測條件。根據該初始基準點以及該四個更新基準點,如表7所示對應的組別/預估年化夏普值,分別為組別20/1.702、組別12/1.602、組別11/1.576、組別1/1.404,以及組別16/1.188。The step of the
於一實施例中,在該類效率配置107之步驟中,將前述組別1、組別11、組別12、組別16,以及組別20所對應初始基準點以及四個更新基準點,並以此為基準而繪製出一類效率前緣曲線(如圖3所示),並以該類效率前緣曲線中的年化夏普值最高者,於此例中即組別20的投資組合視為符合該估測條件。

由上述之說明不難發現本發明的特點,在於本發明的類效率配置估測投資組合的方法,以及非暫態電腦可讀取記錄媒體,其透過投資組合設定,以資產的投資金額必須符合金額遞增單位為限制條件,再參考歷史報酬資料而產生預期報酬資料作為估測基礎,並經由重覆執行而在隨機產生投資組合的集合中,以預估年化夏普值符合估測條件的投資組合為類效率配置者,藉此產生幾近於效率配置的投資組合結果,且由於投資金額符合交易時的遞增金額,所產生的投資組合能夠直接投入交易市場中進行申購,以達到投資組合的估測結果更直覺,且更有效率之功效。From the above description, it is not difficult to find that the characteristics of the present invention lie in the method of the present invention for quasi-efficiency allocation and estimation of the investment portfolio, and the non-transient computer-readable recording medium. Through the setting of the investment portfolio, the investment amount of the assets must meet the The increment unit of the amount is the restriction condition, and then refer to the historical return data to generate the expected return data as the estimation basis, and through repeated execution, in the set of randomly generated investment portfolios, the annualized Sharpe value is estimated to meet the estimation conditions. The combination is a quasi-efficient allocator, thereby producing a portfolio result that is close to efficient allocation, and since the investment amount conforms to the incremental amount at the time of the transaction, the resulting portfolio can be directly put into the trading market for subscription, so as to achieve the investment portfolio Estimation results are more intuitive and more efficient.
