专题二:Relation Between Bond Price & Interest
1. 此专题是for Section 7f and Section 9 的部分原理解释。
主要表达:
If Interest increase , then Price decrease.
If Interest decrease , then Price increase.
If Interest increase , then Price decrease.
If Interest decrease , then Price increase.
看起来很像对,但又很像不对。
Lets do some experiments:
Example 1:
Assume a zero coupon bond have face value 1000 mature in 5 years.
Find the Price if i=5%
Price 上升了,很简单的道理,如果今天跌去4%,就代表我要更高的Present Value 来achieve到5年后的 1000.
If i increase to 6%
Example 2:
Assume a 1000 par value bond with 5% annual coupon mature in 10 years.
Find Price if i = 7%
If i decrease to 6%
因为利息低,所以我需要投资更多的钱来拿到我的回报。If i increase to 8%
When interest low, Bond Price high.
When interest high, Bond Price Low.
