In financevolatility arbitrage or vol arb is a type of statistical arbitrage that is implemented by trading a delta neutral portfolio of an option and its underlying. How to trade option volatility objective is to take advantage of differences between the implied volatility [1] of the option, and a forecast of future realized volatility of how to trade option volatility option's underlying.

In volatility arbitrage, volatility rather than price is used as the unit of relative measure, i. To an option trader engaging in volatility arbitrage, an option contract is a way to speculate in the how to trade option volatility of the underlying rather than a directional bet on the underlying's price. If a trader buys options as part of a delta-neutral portfolio, he is said to be long volatility.

If he sells options, he is said to be short volatility. So long as the trading is done delta-neutral, buying an option is a bet that the underlying's future realized volatility will be high, while selling an option is a bet that future realized volatility will be low.

Because of the put—call parityit doesn't matter if the options traded are calls or puts. This is true because put-call parity posits a risk neutral equivalence relationship between a call, a put and some amount of the underlying. Therefore, being long a delta- hedged call results in the same returns as being long a delta-hedged put. Volatility arbitrage is not "true economic arbitrage" in the sense of a risk how to trade option volatility profit opportunity. It relies on predicting how to trade option volatility future direction of implied volatility.

However, in practice, the only two inputs to the model that change during the day are the price of the underlying and the volatility.

How to trade option volatility, the theoretical price of an option can be expressed as:. Because implied volatility of an option can remain constant even as the underlying's value changes, traders use it as a measure of relative value rather than the option's market price. Even though the option's price is higher at the second measurement, the option is still considered cheaper because the implied how to trade option volatility is lower.

This is because the trader can sell stock needed to hedge the long call at a higher price. Armed with a forecast volatility, and capable of measuring an option's market price in terms of implied volatility, the trader is ready to begin a volatility arbitrage trade.

In the first case, the trader buys the option and hedges with the underlying to make a delta neutral portfolio. In the second how to trade option volatility, the trader sells the option and then hedges the position. Over the holding period, the trader will realize a profit on the trade if the underlying's realized volatility is closer to his forecast than it is to the market's forecast i.

The profit is extracted from the trade through the continuous re-hedging required to keep the portfolio delta-neutral.
