利差交易策略之實證結果

Abstract

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。\r\n \r\n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\r\nSchool/Graduate School: National Chengchi University Executive Master\r\n Of Business Administration, Advanced Finance Class – Risk\r\n Management and Insurance Group\r\nGraduate Student : Lee, Nai-Chun\r\nInstructor: Dr. Kang, Jung Pao\r\nThesis Content:\r\n 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.\r\n 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.\r\n\r\nKey words: carry trade、capital gain、exchange rate、risk indicator
