Volatility & advanced strategies
What is Volatility Arbitrage and how do institutional desks trade options against mathematical models?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Volatility Arbitrage involves taking positions based on a perceived difference between an option's market-implied volatility and a model's forecast of realized volatility, typically hedged with delta-neutral stock or futures positions.
How it works
Institutional desks often combine long or short option positions with continuous delta hedging to isolate and attempt to profit from volatility mispricing rather than directional price movement.
An example
A desk believing a stock's implied volatility of 40% overstates likely realized volatility of 25% may sell options and delta-hedge, aiming to capture the spread between implied and realized volatility.
Risk & limitations
Model-based volatility forecasts can be wrong, and delta-hedging incurs transaction costs and slippage, meaning volatility arbitrage carries real risk and no guaranteed profit despite the term 'arbitrage.'
