1. I Capitalization of Income Method of value
1.1 Capitalization of Income Method of Value
Promised yield-to-maturit P=∑ 台(1+y 如果y>y,则定价过低( underpriced) 如果y<y,则定价过高( overpriced) y’的确定依赖于债券的特征以及现时的市场 条件
Promised yield-to-maturity – 如果 ，则定价过低(underpriced)。 – 如果 ，则定价过高(overpriced)。 – 的确定依赖于债券的特征以及现时的市场 条件。 ( ) = + = n t t t y C P 1 1 * y y * y y * y
例子:一个债券,现价为900元,面值为 1000元,三年到期,息率为6%。得到 y=10.029 如果通过分析,得到 y*=9.00 问题:定价如何?如何确定y?
例子：一个债券，现价为900元，面值为 1000元，三年到期，息率为6%。得到 如果通过分析，得到 问题：定价如何？如何确定 ？ y =10.02% y* = 9.00% * y
Intrinsic value ∑ 1=1(+y 例子:V=924.06 两种程序所得结果的一致性,即价格与 回报率之间的关系
Intrinsic value 例子： 两种程序所得结果的一致性，即价格与 回报率之间的关系。 ( ) = + = n t t t y C V 1 * 1 V = 924.06
为了利用 Capitalization of Income Method of value,必须决定C,P,y的值。 C,和P容易确定 的确定依赖于投资者对债券的特征的 主观看法,以及现实的市场条件。从而 债券分析中,最关键的部分是确定y
