Definition
Volatility arbitrage is a trading strategy that seeks to capitalize on the differences between the forecasted future price volatility of an asset (such as a stock) and the implied volatility reflected in the prices of options pertaining to that asset. Essentially, traders using this strategy aim to profit from their assessments of volatility discrepancies.
Volatility Arbitrage vs. Traditional Arbitrage
| Criteria | Volatility Arbitrage | Traditional Arbitrage |
|---|---|---|
| Focus | Price volatility and options strategies | Price discrepancies between different markets |
| Complexity | Requires understanding of options pricing models | Generally relies on simpler price comparison across assets |
| Risk Factors | Higher due to market movements and implied volatility | Typically lower, focusing on risk-free profits |
| Time Horizon | Can be longer term due to market adjustments | Usually executed in a very short timeframe |
Example
Imagine a scenario where a trader observes that a stock is expected to exhibit a higher future volatility than what the options market has priced in. For example, if a stock has an implied volatility of 20%, but the trader believes the future volatility will be 30%, they might:
- Buy a long call option on the stock (betting it will rise).
- Simultaneously short the underlying shares to hedge potential losses.
This strategy seeks to profit when the market adjusts to reflect the trader’s predicted volatility.

“Remember, volatility is like a wild party guest. You never know how they’re going to behave, but if you can figure out their mood ahead of time, you might have a much better night!” 😂
Fun Facts
- Volatility is often referred to as the “anxiety index” of the stock market. The more unpredictable the market, the higher the implied volatility, and hence more qualifiers for “Fasten Your Seatbelt, It’s Going to be a Bumpy Ride!” 🚗💨
