What’s the difference between a variance swap and a long straddle option trade?
What is the difference between a variance swap and a volatility swap?
Volatility swaps are forward contracts on future realized stock volatility. Variance swaps are simi- lar contracts on variance, the square of future volatility. Both these instruments provide an easy way for investors to gain exposure to the future level of volatility.
How does a variance swap work?
How a Variance Swap Works. Similar to a plain vanilla swap, one of the two parties involved in a var swap transaction will pay an amount based upon the actual variance of price changes of the underlying asset. The other party will pay a fixed amount, called the strike, specified at the start of the contract.
When you would use a long straddle?
A long straddle is established for a net debit (or net cost) and profits if the underlying stock rises above the upper break-even point or falls below the lower break-even point. Profit potential is unlimited on the upside and substantial on the downside.
What is the motivation to use variance swap?
Holders use variance swaps to hedge their exposure to the magnitude of possible price movements of underliers, such as exchange rates, interest rates, or an equity index.
How do you hedge a variance swap?
The variance swap may be hedged and hence priced using a portfolio of European call and put options with weights inversely proportional to the square of strike. Any volatility smile model which prices vanilla options can therefore be used to price the variance swap.
How do you value a variance swap?
The variance swap replication is accomplished using a portfolio of options with different strikes. The construction of this portfolio can be understood intuitively in the Black Scholes model. The sensitivity of a European option to the variance of the underlying asset price depends on the asset price.
Is variance and volatility the same?
While variance captures the dispersion of returns around the mean of an asset in general, volatility is a measure of that variance bounded by a specific period of time. Thus, we can report daily volatility, weekly, monthly, or annualized volatility.
Does variance swap have Delta?
The delta of a variance swap is its price sensitivity to the movement of the underlying asset: ≡ ∂ V ∂ So . The purpose of this short article is to derive an analytic formula for a variance swap delta. It shows that the delta is determined by the volatility skew and the vega of vanilla options only.
How does volatility swap work?
A volatility swap is a forward contract with a payoff based on the realized volatility of the underlying asset. They settle in cash based on the difference between the realized volatility and the volatility strike or pre-determined fixed volatility level.
What is a gamma swap?
A gamma swap on an underlying Y is a weighted variance swap on log Y , with weight function. w(y) := y/Y0. (1) In practice, the gamma swap monitors Y discretely, typically daily, for some number of periods N, annualizes by a factor such as 252/N, and multiplies by notional, for a total payoff.
What is a covariance swap?
A covariance forward contract of two underlying prices/rates. This swap pays the excess of the realized covariance between two assets (such as currencies) over a constant specified at the contract date.
What is vega notional in variance swap?
The vega notional represents the average P&L for a 1% change in volatility. The vega notional = variance notional * 2K. The P&L of a long variance swap can be calculated as: When RV is close to the strike, the P&L is close to the difference between IV and RV multiplied by the vega notional.
How do you find the notional variance?
Variance swaps typically have a notional amount quoted in approximate Vega terms (a dollar value per volatility point). For example, 100,000 USD vega notional. Given any strike (quote in volatility, eg 15%), you can determine the variance notional: Variance Amount = Vega Notional / Strike*2.
What does vega notional mean?
The Vega notional is the approximate cash gain or loss for a 1% difference between the volatility strike (based on the implied volatility in at-the-money option on the underlying) and realized volatility over the life of the volatility swap (really a forward contract on volatility).
Why are swaps used?
Swap is used to have access to new financial markets for funds by exploring the comparative advantage possessed by the other party in that market. Thus, the comparative advantage possessed by parties is fully exploited through swap. Hence, funds can be obtained from the best possible source at cheaper rates.

Are swap rates risk free?
Because a Treasury bond (T-bond) is often used as a benchmark and its rate is considered to be default risk-free, the swap spread on a given contract is determined by the perceived risk of the parties engaging in the swap. As perceived risk increases, so does the swap spread.
Why do swaps spread negatively?
Perhaps the most notable reason for negative swap spreads has been regulation. The regulatory requirement for central clearing of most interest rate swaps (except for swaps with commercial end users) has removed counterparty risk from such swap contracts.
