Volatility Arbitrage Strategies
Volatility arbitrage strategies aim to profit from discrepancies between implied and realized volatility in options markets. These sophisticated trading approaches involve taking positions in options while hedging underlying market exposure to isolate and capture volatility risk premiums.
Understanding volatility arbitrage
Volatility arbitrage is a market-neutral trading strategy that exploits the difference between the implied volatility priced into options and the actual realized volatility of the underlying asset. The strategy is based on the principle that implied volatility, which represents the market's forecast of future volatility, may diverge from historical or realized volatility patterns.
Core components of volatility arbitrage
Volatility spread identification
Traders analyze the relationship between implied volatility surface and historical volatility patterns to identify potential arbitrage opportunities. This involves:
Delta-neutral positioning
Successful volatility arbitrage requires maintaining delta-neutral hedging positions to isolate volatility exposure from directional market movements.
Implementation approaches
Long-short volatility trading
This approach involves:
- Going long options when implied volatility is below expected realized volatility
- Shorting options when implied volatility is above expected realized volatility
- Continuous dynamic hedging of the underlying asset
Relative value volatility trading
Traders exploit volatility differentials across:
- Different strike prices
- Different expiration dates
- Related instruments or markets
