最近準備考試的時候碰到幾題的簡答題有一點苦手 請板上高手給點意見 agree or disagree a. if two bonds have the same dollar duration, yield and price, their dollar sensitivity will be the same for a given change in interest. b. As the duration of a zero coupon bond is equal to its maturity, the price responsiveness of a zero coupon bond to yield change is the same regardless of the level of interest rates. c.duration will be negative? when? ============================================================================== 以上三小題請教板上板友~ 萬分感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 120.126.126.12
