问题如下：
Hightest Capital purchases a seven-year, 6.4% coupon bond and has an intended investment horizon of four years. The Macaulay duration of the bond is 5.86 years. If interest rates increase by 50 bps immediately after buying the bond, Hightest Capital faces:
选项：
A.negative price risk.
negative reinvestment risk.
positive price risk.
解释：
A is correct. Hightest Capital’s investment horizon is four years, which is less than the bond’s Macaulay duration of 5.86 years. Therefore, price risk dominates reinvestment risk and Hightest Capital faces price risk from rising interest rates.
B is incorrect because the increase in interest rates is beneficial for coupon reinvestment. Therefore, Hightest Capital has positive reinvestment risk.
C is incorrect because Hightest Capital faces the risk that the price of the bond will fall as a result of the 50 bp increase in interest rates and therefore has negative price risk.
因為持有不到duration，所以主要受到價格影響，利率上升造成價格下跌，不是應該是正的positive risk?
我理解的是negative price risk表示沒有price risk
