在國際市場上，匯率波動也影響以美元計價的國外市場收益。由於匯率的不確定性，國際投資存在風險的經驗證據。造成這種影響的主要原因是匯率中本地市場回報中的波動性和協變性，這是國際投資風險所致。在許多情況下，協方差的影響是正的，這意味著匯率的變化導致匯率風險的增加。 論文代寫價格:國際投資風險 還發現債券投資的交換風險比股票投資的作用更大。因此，我們可以肯定地說，匯率的變化總是會影響國際投資風險，儘管它可能並不總是增加它。在某些情況下，匯率的變化甚至可以降低外國投資的風險。特別是，當本地市場收益與匯率變動之間的協方差充分負時，它可以抵消匯率變化的正向變化，因此匯率的波動可能導致國際投資風險的降低。 論文代寫價格:國際投資風險 In international market, the fluctuations in the exchange rate also affects the foreign market returns evaluated in terms of dollar. There is empirical evidence of risk in international investments due to the uncertainty of the exchange rates. The main reason for this effect is the volatility and covariance within the returns of local market in the exchange rates which attribute to the international investment risks. In many cases, the effects of covariance are positive which means that the changes in the rate of exchange leads to increase the exchange risk. 論文代寫價格:國際投資風險 Also it is found that the exchange risk in bond investments plays greater role than that in the stock investments. Thus we can conclusively say that the changes in the exchange rate always effects the international investment risk, though it might not always increase it. There could be some situations where the changes in the exchange rate could even reduce the risk of foreign investment. Specially, when the covariance between returns of the local market and changes in the exchange rate is adequately negative, it can offset the positive variance of the changes in exchange rate and thus the volatility of exchange rate could lead to reduction in risk of international investment.
