匯率報酬的三因子 / 3-factor in determinant of exchange rate return

黃祺真, Huang, Chi Chen Unknown Date (has links)
了解影響匯率報酬的因素不論在交易、避險或是投機方面,皆是非常備受關注的議題。本文研究目的是為探討同時運用市場超額報酬、利差交易和動能策略是否更能解釋外匯市場的超額報酬,即表示在實證分析上應用三因子模型有更佳的解釋力。 而本文中使用OLS迴歸及 Fama-Macbeth 兩步驟橫斷面迴歸分析,結果發現皆顯示相較於 Lustig, Roussanov, and Verdelhan (2011) 論文裡的兩因子模型,加入動能策略因子形成的三因子模型在未包含交易成本及考慮交易成本的情況下皆應該是較適切的模型。

總體經濟指標與利差交易之分析 / Analysis of Macroeconomic Indicators and Carry Trade

周長隆 Unknown Date (has links)
本研究探討國際投資人是否能夠藉由總體經濟指標、泰勒法則、以及匯率資料,捕捉無拋補利率平價假說的成立時間,以及判斷市場多空轉換的時間點,做好相對應的利差交易投資策略來獲得持續的超額報酬。利用時序變動型馬可夫轉換模型,分析2002年9月到2013年9月,共133個月之匯率資料,將樣本區間內的超額報酬資料根據資料特性利用模型分為兩個情境,再加入總體經濟指標變數、泰勒法則、以及匯率資料分析比較情境轉換因子對利差交易之超額報酬的關係。 經過實際驗證後的結果,發現泰勒法則雖然在文獻中扮演捕捉總體市場趨勢的變數,但在本研究之實證結果中,與利差交易之超額報酬的關係並不明顯,推測泰勒法則的合成過程可能隱瞞或消弭原始資料之資料特性。此外,觀察樣本區間內實證測試結果,發現實質匯率之資料,在景氣繁榮的金融穩定期時,能夠扮演預警的角色,因為根據二情境時序變動型馬可夫轉換模型之情境轉移機率矩陣估計的估計結果,發現實質匯率在多頭市場的情況下對於情境轉換有顯著的影響力,因此國際投資人能夠將實質匯率作為捕捉市場反轉與否的信號,建構相對應之投資策略,將情境因子列為考量,藉由預測下一期之情境使得投資人對於投資產生擇時機會,不論是發現市場將從多頭轉空,提早出場、或是預期市場會從空頭轉多,開始布局,都有助於增加利差交易之超額報酬。

外匯市場利差交易分析 / Analysis of The Carry Trade in Monthly Currency Market

林比莉, Lin, Bi Li Unknown Date (has links)
本研究主要在探討外匯市場中從1983年11月至2015年10月期間的利差交易策略是否存在超額報酬,並進一步解釋造成利差交易超額報酬的原因,使用61個國家之貨幣建構投資組合,從交易成本、景氣循環波動以及套利限制三個方面來解釋利差交易超額報酬的存在。實證結果發現,以較短月期的遠期外匯建構投資組合,這樣的利差交易策略可以得到較高的報酬,相反地,若以較長月期之遠期外匯建構投資組合,利差交易報酬較低,同時也發現利差交易的超額報酬可以被交易成本部分解釋,景氣循環變數亦可解釋利差交易超額報酬,逐步迴歸結果篩出之總體經濟變數與利差交易超額報酬呈現顯著結果,最後將套利限制加入考慮後,發現投資人在從事利差交易策略時並不會被套利限制所阻擋,貨幣之國家風險與異質性波動度皆不會影響投資人從事套利行為。

考量商品貿易之匯率報酬評價 / Determinant of exchange rate return-considering commodity trade

王可佳, Wang, Ke Jia Unknown Date (has links)
本研究欲探討國家商品貿易特性在匯率報酬評價中扮演的角色,決定匯率報酬的因素非常多,包含利率、市場波動、國際貿易及國家政治等非常廣泛的因素,而國家商品貿易特性也會是影響匯率報酬評價的可能因素之一。本研究以「進口比率」(Import Ratios) 衡量國家的商品貿易特性,也以該數值建構投資組合。研究結果發現,去除商品貿易特性特殊之國家後,進口比例(Import Ratio)越高之投資組合,其遠期外匯貼水也偏高,且外匯超額報酬也隨之遞增。 在Ready, Roussanov, and Ward(2013)論文中認為,國家的商品貿易特性是造成不同國家利率高低差異的原因,所以該作者認為國家商品貿易特性極有可能是利差交易背後的原因。然而,本研究的Fama-Macbeth 兩步驟橫斷面迴歸實證結果發現,國家的商品貿易特性確實是造成國家利率差異的因素之一,但利差交易背後的風險背後的因素,雖然包含國家商品貿易因素,但仍包含其他因素,且商品貿易因子(IMX)無法取代利差交易因子(HML)在外匯超額報酬評價模型中的角色。 此外,本研究亦嘗試在Lustig所提出之市場因子(RX)和利差交易因子(HML)的兩因子模型中,再額外加入商品貿易因子(IMX),構成匯率評價的三因子模型,但研究結果發現不論是在遠期外匯貼水投資組合或商品貿易投資組合中,三因子模型都沒有優於兩因子模型。 / There are many factors in determinant of exchange rate returns, such as interest rates, market volatility, international trade and politics. The purpose of this research is considering commodity trade in the pricing model of excess return of currency market. This research use “Import Ratios” to measure the characteristic of different countries’ commodity trade. We use import ratios to construct “Import Ratio Sort Portfolio”. After removing the countries which commodity trade characteristics are special, we could see when import ratios is higher, the forward discount and exchange rate return are also higher in import ratio sort portfolio. Ready, Roussanov, and Ward(2013) thought the commodity trade is the reason that cause interest rate differences between countries. In this research, the result of Fama-Macbeth two-step regression show that commodity trade is one of the reasons that cause interest rate differences. It means that there are other risks behind carry trade. In the pricing model of excess return of currency market, HML factor can’t be replaced by IMX factor. We also try to construct three-factor model, which consider excess return, carry trade, and commodity trade simultaneously. But the result shows that three-factor model can not have better explanatory power than Lustig, Roussanov, and Verdelhan(2011)’s two-factor model.

以動能交易與利差交易分析外匯投資組合績效 / The Performance Analysis of Using Momentum and Carry Trade in Currency Portfolio

歐哲源, Ou, Che Yuan Unknown Date (has links)
本篇論文主要在外匯市場建立市場投資組合、利差交易投資組合與動能交易投資組合,探討透過不同情境適當改變投資組合比重配置,是否能夠顯著提升交易策略的報酬表現。 以1999年1月至2015年10月為樣本期間,根據28個國家外匯市場資料建構市場投資組合、利差交易投資組合與動能交易投資組合等,之後根據三種投資組合報酬情況透過馬可夫情境轉換模型區分成三種情境。按三種情境的各種投資組合超額報酬表現,再利用馬可維茲的平均數-變異數投資組合模型配置各情境下各項交易的比重,再依據計算出的預期情境與相對應比重進行投資。其結果顯示在樣本期間內,本篇論文的交易策略相較於外匯市場投資組合、利差交易投資組合與動能交易組合有較佳的投資表現。 在樣本外測試部分,採用自2012年中開始的連續情境二資料進行分析。報酬方面,在其他交易型態呈現負報酬較多情況下,就本文交易策略而言,投資者隨時根據其各種交易平均報酬與共變異數進行交易比重配置,適時放空交易策略或投資無風險資產,產生正報酬。但從標準差可以推斷投資者面對未來的不確定,在整個樣本外期間歷時的34個月當中標準差亦無法有效降低,說明了投資者面對下一期總體環境的高不確定性。 / In this thesis, we mainly investigate whether it could improve the performance of currency portfolio by adjusting weights among carry trade, momentum and market return in foreign exchange market under different kinds of regimes. Based on a sample of 28 market currencies, we form three kinds of transactions in our portfolio, including carry trade, momentum, and market return. Under Markov switching model, we divide the sample period into three regimes, and then determine weights among carry trade, momentum and market return by parameters of each re-gime using Markowitz mean-variance analysis. Finally, we invest different weights among three transactions according to each expected regime. We find the result that although the return of the strategy is just a little higher than the carry trade, the risk is much lower compared to other transactions. In our out-of-sample testing, we analyze the performance by using the data of the regime two which begins September, 2012. With the respect to the return, most of other risky transactions have negative return, but we get positive return by adjusting the long position and short position according to the result of the mean-variance anal-ysis. However, we can not effectively reduce risk by using the strategy, and in the meantime it can explain the high uncertainty investors face toward the next period.

利差交易策略之實證結果

李乃君 Unknown Date (has links)
利差交易(Carry Trade)是在各種貨幣的利率水平上進行套利的交易以獲得價差收益的交易型態。而利差交易在這幾年創造出諸多研究的方向;利差交易又稱為套息交易,即借入低利率的貨幣,以購買其它高收益的投資工具,如高利率貨幣、股票、或是實物資產等,進而從中賺取其間的利率及匯率差價。諸如債券或國庫券等現貨金融工具所帶來的收益與該項投資的融資成本間的差額。 利差交易多在市場處於穩定低風險狀況下時,才能夠得到穩定的報酬率,因此如何客觀準確的評量目前市場所處的風險狀態,以獲得相對平穩又較佳的收益是主要的研究方向。本研究以如何求得利差交易裡面各項最佳且保持穩定性的參數與指標,假設利差交易可以經由衡量某些風險指標的平均值,並當風險指標低時建立利差交易部位,反之,當風險指標高時結束利差交易,甚至更積極進行反向利差交易,以求達到穩定報酬率的目標。 / Title of Thesis: Empirical Performance of Carry Trade Trading Strategy School/Graduate School: National Chengchi University Executive Master Of Business Administration, Advanced Finance Class – Risk Management and Insurance Group Graduate Student : Lee, Nai-Chun Instructor: Dr. Kang, Jung Pao Thesis Content: Carry trade bases on interest rate differences of many currency pairs to make capital gains and interest income and it creates many research topics in recent years. Carry trade borrows low yield currencies and invests other high yield targets such as high yield currencies, stocks, or real assets to get interest incomes and capital gains from foreign exchange rates. Only when a foreign exchange market is under stable and low-risk conditions, carry trade can achieve stable return rates. Therefore, how to objectively evaluate current market risk situations to get relatively stable and more returns is the main research topic of this thesis. This thesis reports how to get optimal and consistently stable parameters and indicators of carry trade. It assumes that carry trade can build positions by measuring some mean values of risk indicators when risk indicators are low. On the contrary, it ends the trade when risk indicators are high and even actively short carry trade positions to achieve stable return rates. Key words: carry trade、capital gain、exchange rate、risk indicator

全球運籌佈局資金配置與管理-以聚陽實業個案分析

游濱福 Unknown Date (has links)
企業在國際化的擴展下,往往要面對許多不同國家內的客戶群,配以當地的各國的貨幣與銀行帳戶,當然企業受到外匯風險的衝擊也因此提高;當匯率一有波動時,對於企業的獲利、淨現金流量及市價對將有所影響。因此為了更有效率去管理企業的財務運作,規避外匯風險就成為國際化企業的財務單位,所需積極面對的重要事項,特別在企業風險和國際化成正相關時。 本研究試著將風險值VaR概念,從一般金融機構風險值的研究擴大應用於公司外幣資產組合,以之分析其對公司價值的影響程度,並為個案公司尋找合適的避險策略或是較佳的資金配置,以期能降低個案公司其風險值VaR對公司的衝擊。 研究可知,當採取適當的資金配置比例時,對於國際化企業而言,是能有效降低外匯風險的資金配置。 / Enterprises in the international expansion, they have to face many different customer base within the country, countries with local currency and bank accounts. Of course, the impacts of foreign exchange risk also increase. When the exchange rate has some fluctuations in local, enterprises will have an impact on profit, net cash flow and market value. Therefore in order to more efficiently to manage the financial operation. So finance department of international business must require facing the important issues that evasion of foreign exchange risk. Particularly in the enterprise risk and the internationalization is relevant. As well as Enterprises look for hedge strategy or a better allocation of funds. This study will try to use the concept of Value-at-Risk, “VaR”. Let the VaR of financial institutions from the general study of broadening the application of the value of foreign currency assets of portfolio companies. Then try to analysis their implications for the impact of the value of the company. And hope to reduce the VaR of Enterprises its impact on the company. Research shows that when appropriate proportion of the funds allocation for the internationalization of enterprises, it can effectively reduce foreign exchange risk.

利差交易新風險因子:無風險實質利率 / Risk Free Real Rate as a New Risk Factor to Carry Trades

林品傑 Unknown Date (has links)
未拋補利率平價說的不成立,衍伸出平均報酬大於零的利差交易(carry trades)。 過去基於風險解釋的文獻,提出各種風險因子欲歸因此套利策略的不尋常超額報酬,實為承擔不同風險的額外補償,亦即風險溢酬(risk premium)。 不同的風險因子可略分為兩派:一為有經濟理論根據,卻在實證上未獲支持的「消費成長因子」;二為在實證上具顯著解釋力的「外匯相關因子」, 卻無理論依據而難以賦予利差交易報酬經濟意義。 本文主張以無風險實質利率作為風險因子。此想法源於隨機貼現因子(stochastic discount factor)之定義式以及現實環境中的觀察。 我們的實證發現,實質化的美國公債利率對於利差交易的報酬有顯著的定價能力。 本文更進一步驗證,本因子甚至比起文獻上的外匯波動度因子,更具顯著的定價能力。另外,本因子亦能解釋動能利差交易之報酬,此為高減低因子所不能定價的報酬。

NDF利差交易策略實證 / FX Carry Trades Strategy:the Case of NDF currencies

郭俊宏 Unknown Date (has links)
在本篇文章中我們希望能建構一個以NDF貨幣為主的利差交易最適交易策略,並將以往使UIP無法成立的各種因素利用羅吉斯迴歸模型及線性迴歸模型融合成一個平倉指標,用以適時地結清部位甚至反向操作,並審視各種變數進入平倉指標對於報酬的預測能力,以期此交易策略能夠達到更高的報酬表現。 而實證結果顯示反映資本控制程度的受拋補利差(Covered Interest Differential)與市場流動性風險指標之一的泰德價差(TED Spread)能有效捕捉重大虧損的發生,投資組合利差(Carry)對於報酬也有顯著影響但程度不如受拋補利差。此外也發現使用多頭策略(Long-Netural)相對於多空策略(Long-Short)能到更高的夏普值,而利用所選變數在每周針對逐一貨幣篩選也會比單純判斷每周是否進行利差交易得到更好的夏普值。

外匯市場之國家風險分析 / Country risk analysis in currency market

林毓翔 Unknown Date (has links)
本研究對1985/1至2016/10期間,37種貨幣的超額報酬與國家風險進行實證分析,以The PRS Group發佈的ICRG綜合風險評級做為國家風險的衡量指標。各國貨幣分別進行時間序列分析的結果顯示,單一國家的國家風險與該國貨幣的匯率走勢及超額報酬並不存在顯著的關聯。 投資組合分析的結果,對高國家風險貨幣與低國家風險貨幣分別執行利差交易,結果顯示兩者的超額報酬並沒有顯著差異。而動能策略在高國家風險貨幣則可以獲得顯著較高的超額報酬。 Fama-Macbeth二步驟迴歸分析結果顯示,高國家風險的投資組合確實擁有較高的因子負載量,然而國家風險因子的市場價格,也就是承受一單位 β_CRISK獲得的國家風險溢酬太低不顯著,因此國家風險無法幫助解釋貨幣報酬。 / We empirically investigate the relation between currency excess returns and country risk, as measured by the ICRG comprehensive risk rating issued by The PRS Group, of 37 currencies during 1985/1 to 2016/10. The result of the single currency time series analysis shows that there is no significant correlation between the country risk and the exchange rate movement, also the currency excess return. As a result of the portfolio analysis, there is no significant difference in excess returns when we execute carry trade respectively on high country risk currencies and low country risk currencies. While the momentum strategy in the high country risk currencies can generate significantly higher excess return. The results of the Fama-Macbeth two-step regression show that the high-risk portfolios do have a higher factor loading, whereas the country risk factor's market price, that is, the country risk premium received by a unit of β_CRISK, is too low. Therefore, country risk cannot help explain currency excess return.
