自交易所交易基金（ETF）推出18年以來，全球資產總額成長近300倍，其中，臺灣市場之ETF推出已近2年，若依國際市場發展趨勢，將可能成為投資人主要投資工具之一，有探討其表現與特性之必要性。本研究共分析三個主要議題：（1）探討臺灣ETF的淨資產價值和臺灣50指數的表現差異；（2）探討臺灣ETF在臺灣證券交易所的交易價格和TTT的淨資產價值關係；（3）探討臺灣ETF的報酬表現，並觀察其它股票型基金的表現。研究發現：（1）臺灣ETF報酬率低於臺灣50報酬指數報酬率；（2）臺灣ETF的淨資產價值與市價差距極小，且前期差距對下期差距具解釋能力；（3）臺灣ETF的淨資產價值與市價差距對於成交量解釋並不顯著，套利可能性相當低；（4）臺灣ETF交易量之擴大仍面臨市場結構性瓶頸。研究成果對於臺灣ETF之發行管理與交易策略具有參考價值。
