台幣外匯指數與各國外幣匯率指數及類股指數連動性探勘之研究

The Study of Co-movement between International Exchange Rates and Categorical Stock Indexes in Taiwan

指導教授 : 廖述賢 陳登源

摘要


外匯市場是全球交易量最大的單一市場,規模比期貨與股票交易市場總和還要大,加上其二十四小時不停營運的特色,外匯市場在國際金融市場上有著舉足輕重的地位。隨著國際金融貿易日趨自由化,各國貨幣的流通亦日趨頻繁,了解貨幣之間的連動性,可以提供投資人在投資、避險等方面做決策參考。 以往相關研究大多以財務計量方法為主,本研究則是運用資料探勘中的關聯性法則,探討各國外幣匯率間連動性,以及與類股指數之間的連動性。首先蒐集外幣匯率指數資料和類股指數資料,並建立資料庫,再以資料探勘技術找尋關聯性規則,以建議投資者進行投資可採用的投資思維。在資料探勘技術中,本研究選擇關聯法則中的Apriori演算法,以最小支持度、最小可靠度與增益值作為門檻值,尋找關聯法則,期望能提供投資人不同的投資思考方向。 研究結果在外幣連動方面,運用投資組合基本原則,歸納出三種投資組合箱,提供投資人在不同的市場行情裡操作參考;在外幣和類股連動方面,由於受金融海嘯影響,類股多呈現跌勢,因此歸納出一組投資組合箱供投資人參考。另外針對外幣連動因素加以探討,發現外幣的連動有區域性、政策性以及外幣本身特性,都會影響外幣之間的連動性。
