美國次貸危機對亞洲股票市場與指數期貨波動性的影響

The Impact of the U.S. Subprime Mortgage Crisis on Asian Index Futures and Stock Market Volatility

摘要


本研究探討美國次貸危機後,亞洲市場大量雜訊交易者進入期貨市場交易,使得交易市場資訊環境改變,對期貨與現貨市場波動性的影響為何?藉以檢驗美國次貸危機事件後,聯繫投資人之間資訊不對稱性是否增加或減少。本文實證結果發現,在美國次貸危機事件後,大部份亞洲地區包括台灣、韓國、泰國、新加坡與香港,都顯著增加期貨與現貨市場價格波動。並認為此情況會增加投資人之間資訊不對稱與交易市場不穩定性,並加大市場參與者的投資風險。
