问题如下：

4. The effective duration of Bond #4 is closest to:

选项：

0.76.

1.88.

3.77.

解释：

B is correct.

The effective duration of Bond #4 can be calculated using Equation 3 from the reading, where Δ Curve is 20 bps, PV– is 101.238, and PV+ is 100.478. $PV_0$ , the current full price of the bond (i.e., with no shift), is not given but it can be calculated using Exhibit 3 as follows:

S= Interest Rate Scenario

C=Cash Flow (% of par)

R=One-year Interest rate (%)

V= Value of the Callable Bond’s Future Cash Flows (% of par)

Thus, the effective duration of Bond #4 is:

Effective duration = $frac{101.238-100.478}{2\times(0.0020)\times(100.873)}=1.88$

嗨，从没放弃的小努力你好：

分母的△y是0.002而不是0.003，表4给的V-与V+是变动20bp时的值。

可是callable bon不是最后的答案不能超过100吗？
