投资者为什么喜欢凸性?
• 曲率大的债券价格在收益下降时的价格上升大于在收益上涨时的价格下降。 • 收益率越不稳定，这种不对称性的吸引力就越大。 • 对于凸性较大的债券而言，投资者必须付出更高的价格并接受更低的到期收
益率。

可赎回债券
• 当利率下降时，债券的市场价格有一个上限，债券价格不会超过其赎 回价格。
$1,000/1.053.7704 = $831.6717。价格下降 了0.0359%。

Risk Adjusted Performance: Treynor

rp = Average return on the portfolio
rf = Average risk free rate ßp = Weighted average beta for portfolio
24-2
Introduction
• Two common ways to measure average portfolio return: 1. Time-weighted returns 2. Dollar-weighted returns • Returns must be adjusted for risk.
24-7
Time-Weighted Return
53 50 2 r1 10% 50 54 53 2 r2 5.66% 53
rG = [ (1.1) (1.0566) ]1/2 – 1 = 7.81% The dollar-weighted average is less than the time-weighted average in this example because more money is invested in year two, when the return was lower.

M Measure
• Developed by Modigliani and Modigliani • Create an adjusted portfolio (P*)that has the same standard deviation as the market index. • Because the market index and P* have the same standard deviation, their returns are comparable:

例 25.1 汇率风险
假设英国无风险利率为10% 现在的汇率是 1英镑兑2美元 。
一个投资者有20,000 美元，即可以购买 10,000 英镑，一年后投资可得11,000英镑。
如果汇率下跌为1英镑兑1.80美元那么最终 只能得到19, 800美元, 损失了200美元。
对美国投资者而言，这项投资并不是无风 险的。

Rule 3 Holding the coupon rate constant, a bond’s duration generally increases with its time to maturity
INVESTMENTS | BODIE, KANE, MARCUS
16-14
Rules for Duration
Rule 4 Holding other factors constant, the duration of a coupon bond is higher when the bond’s yield to maturity is lower
Rules 5 The duration of a level perpetuity is equal to: (1+y) / y
• Bonds with greater curvature gain more in price when yields fall than they lose when yields rise.
• The more volatile interest rates, the more attractive this asymmetry.
