## 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 is volatility swap calculated?

Payoff for a Volatility Swap

This is done by multiplying the notional value of the contract by the difference between the actual and the predetermined volatility. This predetermined level of volatility is a fixed number that is a reflection of the market’s expectation at the time of inception of the forward contract.

Variance swaps are used by institutional traders. A retail or individual trader can trade volatility through options, but a pure volatility bet would involve hedging out the delta (directional) risk.

## How does 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.

## Does variance swap have Delta?

Yes. Volatility swaps can have a delta due to the discretization of time and due to volatility surface dynamics in exactly the same way as a variance swap.

## Is variance and volatility the same?

Variance is a measure of distribution of returns and is not neccesarily bound by any time period. Volatility is a measure of the standard deviation (square root of the variance) over a certain time interval. In finance, variance and volatility both gives you a sense of an asset’s risk.

## What are swap agreements?

A swap is an agreement for a financial exchange in which one of the two parties promises to make, with an established frequency, a series of payments, in exchange for receiving another set of payments from the other party.

## What is vega notional amount?

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.

## What is a knock out variance swap?

A twist on the well-known corridor variance swap introduces a knock-out bar- rier on the up-side, such that the trade terminates upon spot reaching the barrier, paying the corridor variance accumulated to date.

## 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.

## What causes volatility smile?

What Does a Volatility Smile Tell You? Volatility smiles are created by implied volatility changing as the underlying asset moves more ITM or OTM. The more an option is ITM or OTM, the greater its implied volatility becomes. Implied volatility tends to be lowest with ATM options.

## How do you trade dispersion?

Dispersion trading consists of taking a position in an index option and the opposite option stance in all the index components. Effectively, by selling the former and buying the latter traders are placing opposite trades on the volatilities of an index and its components and therefore gaining exposure to correlation.

## Why do variance swaps have Delta?

The reason for the variance swap having delta is the presence of the skew in implied volatility (for details, see de Weert (2008), Chapter 23): as the spot price goes down, the at-the-money implied volatility will grow up and hence increase the variance swap price.

## 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.

## How do total return swaps work?

In a total return swap, one party makes payments according to a set rate, while another party makes payments based on the rate of an underlying or reference asset. … The receiving party also collects any income generated by the asset but, in exchange, must pay a set rate over the life of the swap.

## Does a variance swap have gamma?

While variance swaps provide constant gamma exposure across time, their variance vega exposure is a linear function of time to expirationexhibiting significant exposure to changes in implied volatility on a mark-to-market basis early in the life of the contract with little exposure to changes in implied volatility …

## What are variance futures?

Variance futures are futures contracts written on realized variance, or standardized variance swaps. The S&P500 variance futures are not model based, so the assumptions underlying the index do not seem to have been clearly understood.

## What is option variance?

In finance, an option on realized variance (or variance option) is a type of variance derivatives which is the derivative securities on which the payoff depends on the annualized realized variance of the return of a specified underlying asset, e.g. stock index, bond, exchange rate, etc.

## How do you find volatility of a stock?
