同學,早上好。
這個需要乘以YTM,相當于基于整體收益率的變動是多少百分比,原版書勘誤了,勘誤如下,
First, we solve for the expected change in YTM based on a 99% confidence interval for the bond and a 1.75% yield volatility over 21 trading days, which equals 65.9 bps = (6.174 bps × 2.33 standard deviations × 21).We can quantify the bond’s market value change using either a
duration approximation or the actual price change as follows. We can use the Excel MDURATION function to solve for the bond’s duration as 12.025. We can therefore approximate the change in bond value using the familiar (?ModDur × ΔYield) expression as $3,605,636 = ($50 million × 0.91 × (?12.025 × .00659)). We can also use the Excel PRICE function to directly calculate the new price of 88.982 and multiply the price change of 2.018 by the face value to get $1,009,000.

6.174是什么?21不需要開根號?

同學,早上好。
6.174=1.75%*3.528%,代表一標準差下每日的利率變化。21要加根號的,勘誤有些還是會錯。 -

百題case 6的第五題是不是也錯了?我計算出來的結果是598166.74,解析漏了YTM,麻煩老師看下?

是的,因為協會是最近勘誤的,百題之前編寫的,所以會遵循原版書原來的邏輯,當前按照最新的勘誤計算即可。
