各位大師
請問一下 這樣的問題
關於時間和所謂的折價問題讓我很困惑
A bank accepted bill of exchange with
a face value of $1million 面額1,000,000
maturing on 2008/5/31 期滿日
purchased on 2008/2/26 購買日
“yield”殖利率 為6.2% p.a.
(即是票券訂價用的利率 priced using a simple interest formula)
and sold on 2008/4/30賣出 賣出是以at a simple discount of 5.3% p.a.折價賣出
Calculate the force of interest
計算出此交易的息力(以日為單位的息力), per day (assuming a constant force of
interest over the period this bill was held.)
以上
請財務數學大師幫忙
我的想法如下
1,000,000/1+[(95/365) *0.062)] =984,119.2806
購買價格
1,000,000*[1-(31/365)*0.053]=995,498.6301
以simple discount賣出
此票券從原購買日之價值 到賣出那天應該變為 984,119.2806*[1+(64/365)*0.062+1]
=995,486.5323
然後要如何求出此買入賣出交易的每日息力 (若假設息力為Constant)
至於我的價格算法有錯嗎??
謝謝幫忙
