问题如下：
Which of Winslow’s statements about carry trades is correct?
选项：
A. Statement I
B. Statement II
C. Statement III
解释：
A is correct.
Carry trades may or may not involve maturity mis-matches. Intra-market carry trades typically do involve different maturities, but inter-market carry trades frequently do not, especially if the currency is not hedged.
B is incorrect. Carry trades may involve only one yield curve, as is the case for intra-market trades. In addition, if two curves are involved they need not have different slopes provided there is a difference in the level of yields between markets.
C is incorrect. Inter-market carry trades do not, in general, break even if each yield curve goes to its forward rates. Intra-market trades will break even if the curve goes to the forward rates because, by construction of the forward rates, all points on the curve will earn the "first-period" rate (that is, the rate for the holding period being considered). Inter-market trades need not break even unless the "first-period" rate is the same in the two markets. If the currency exposure is not hedged, then breaking even also requires that there be no change in the currency exchange rate.
您好 之前提問過Statement III， 但還是不懂錯在哪裡？如果是按照covered interest rate parity, 往forward rate移動的話，不是應該會把兩國利差剛好吃掉 break even嗎？謝謝！
