摘要: 
本研究致力於以各國ETF建立國際投資組合,ETF具備立即申購與贖回之特性,使基金貼近淨資產價值且不易受流動性風險影響,較受機構投資人偏好,但指數之追蹤誤差與追蹤差異為ETF投資人關注的議題,故本文首先檢視各國ETF之追蹤有效性,實證結果大多數ETF皆可有效追蹤指數,因此ETF確實為適合的投資工具。由於ETF具備一籃子股票特性,個別公司的非系統性已被分散,如何降低主權風險最為國際投資人所關注,從實證結果可知,各國與各洲區間之相關係數逐年增加,顯示跨國投資達到主權風險分散的程度有限,此外由naive diversification也證實投資各國ETF的風險分散程度逐年遞減,在考量邊際成本下,選取一最適投資樣本數實有其必要性,本研究藉由最適樣本數建立風險最適之國際投資組合,實證結果發現投資過去sharpe比率較大的國家可獲得優於比較標準之投資收益。

This research is dedicated to construct international portfolio by country ETF which posses the characteristics of creation and redemption and it’s market value is close to net asset value. Institutional investors prefer ETF because it can avoid the liquidity risk, but they concern with the topics about tracking error and difference of ETF. First, we check the tracking effectiveness of ETF and found out that most ETF can track the index well. Invest in one unit ETF is equal to invest in a bundle of stocks , the individual non-systematic risk has been diversified. As a result, international investors must recognize how to reduce sovereign risk efficiently. From the empirical results, we found that the correlation coefficients between each country and state are getting higher in the long run , therefore the international diversification benefits of sovereign risk are worse. On the other way, the naive diversification also demonstrate that international diversification benefits are reduced. Considering the marginal cost and other transaction cost, it is necessary to determine a optimal sample. At last, we construct international portfolio by optimal risky portfolio, and found that the performance is better than the benchmark.
