1. Because the 票面值( HK$1,000) = 發行價 (HK$1,000), therefore,債券在在發行當日的到期孳息率=息票利率: 12%
2. Let R=該債券的現時孳息率
息票=$1,000*12%=$120
1,169.36=120/(1+R) + 120/(1+R)^2 + 120/(1+R)^3 + 1,120/(1+R)^4
R=7%
Therefore, 債券的孳息率 is 7%
3. The market interest rate has dropped in these 2 years, that's why the 孳息率 fell also.
4. 該債券兩年前的市價波幅較大, because shorter the time to maturity, smaller the 波幅.
5. Assuming the market interest rates does not change, 投資的回報率
equals 孳息率 = 7%.
6. Market interest rate might be changed.
7. As there are many types of investors in the market: traders, hedgers and arbitragers. Traders may hold different views with the market. Moreover, hedgers will need to reduce their bonds exposure thus buying and selling the bonds in accordance with their needs. Lastly, the arbitragers will buy or sell the bonds if arbitrage opportunities and they have no views on the movements of interest rates.
