原題意是說 某人發表了一個statement : A receiver swaption permits the holder to enter into a pay floating position and is equivalent to a put option. 個人認為pay floating position 跟 as a put option都對, 但解答說receiver swaption is equivalent to a call option. 但receiver是當swap rate decrease時才valuable, 所以當預期 rate falling 時也會買reciever swaption啊。 題目也沒有說是equivalent to take put option against bond price or interest rate. 有各位高手能協助解釋這題嗎?還是答案錯了? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.124.122.57
