问题如下：
An investor purchases a 12-year, 5.8% annual bond and intends to sell it after 10 years. The Macaulay duration of the bond is 8.97 years. If interest rates fall by 75 bps immediately after the purchase of the bond, the investor faces:
选项：
A.negative reinvestment risk.
no reinvestment risk.
positive reinvestment risk.
解释：
A is correct. The investor has an investment horizon of 10 years, which is greater than the Macaulay duration of 8.97 years. Therefore, reinvestment risk dominates price risk.
B is incorrect because the investor faces reinvestment risk because the investment horizon is higher than the Macaulay duration.
C is incorrect because the investor faces negative coupon reinvestment risk, not positive coupon reinvestment risk, since the coupons will be reinvested at a lower interest rate.
reinvestment risk dominates price risk意味着negative reinvestment risk？
