2023-08-15 13:45老師,第三題求variance swap時(shí),老師有先說了是sell volatility,所以收fixed variance,支 realized variance,然后計(jì)算時(shí)是 fixed variance-realized variance,需要這樣看誰減誰嗎?記得公式是 realized variance - K方。答案中也是。就按公式算可以嗎?

同學(xué),下午好。公式里默認(rèn)是買方的。這里是賣方,所以是收fixed variance,支 realized variance,然后計(jì)算時(shí)是 fixed variance-realized variance
如果是買方:
In a variance swap, the buyer of the contract will pay the difference between the fixed variance strike agreed on in the contract and the realized variance (annualized) on the underlying over the period specified and applied to a variance notional。
variance swap買方,會(huì)支付(variance strike- realized variance),所以是支K方,收realized variance。而最后的盈利就是 realized variance - K方
