请问利率波动率下降,CVA不是应当上升吗?波动率降时,二叉树上端利率出现显著下跌(因为高利率节点的波动幅度 σ * r 直接收缩),下端利率由于被有效下限(如0%)托底,绝对变化空间本就不大。所以总体r下跌,风险敞口和CVA不是应该上升吗?
未解决这里说的是YTM 是等于 ∑(t×wt /Mac.D ×St), 如图2,对吗?但是Mac.D 不是由YTM算出来的吗,某一期的现金流现值除于总现金流现值之和,但是求导算修正久期的时候,把r看作单一变量,并不是s1, ..., sn, 即应为YTM, 那不是一个循环求解?如果有证明过程,可以看看吗
老师你好,“Implied volatility is higher for lower strike prices than for higher strike prices; therefore, out-of-the-money put options will generally be more expensive than out-of-the-money call options.”为什么可以推出价外看跌期权比价外看涨期权更贵?然后有怎么更选项B联系起来?选项B:Using out-of-the-money options to hedge is more expensive than establishing a long position with out-of-the-money options,为什么价外期权对冲比long一个价外期权更贵? 不太理解这道题在考什么,请解释。
老师好,不太理解这道题目里为什么is incorrect in her description of pricing differences between the spot and futures markets based on accrued interest. 请详细解释Bond Futures的报价和Spot Bond Market的报价有什么相同和不同之处以及联系。“Typically, bond futures are quoted with pricing that reflects interest accrued since the last coupon payment. Therefore, in markets where spot prices are quoted “clean” rather than “dirty,” there can be some disconnect between spot and futures prices.”为什么题目中这么陈述是错误的?

- Growth due to capital deepening 是αΔK/K还是ΔK/K
- 这题为什么是选C?
- 请老师讲解一下这个题目
- 老师,第二题可以在解释一下原理吗?
- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
- CDS的long和short是不是反过来的?就是long CDS代表看涨目标公司credit,所以是卖出一份CDS合约?
- 很迷惑到底是long call+ short stock还是long stock+short call构建无风险资产
- 为啥accrued interest over contract life是0?
