A risk reversal is an options strategy used primarily for hedging purposes. It involves the simultaneous purchase of an out-of-the-money (OTM) call option and the sale of an out-of-the-money (OTM) put option, or vice versa.
Definition
In financial markets, a risk reversal refers to a combination of an options position where an investor purchases one type of option and sells another to manage or hedge risk.
How It Works
Risk reversals work by taking advantage of the differences in the valuation of the call and put options. Here’s how it is typically structured:
- Bullish Risk Reversal: Involves buying an OTM call option and selling an OTM put option.
- Bearish Risk Reversal: Involves selling an OTM call option and buying an OTM put option.
This strategy can be used to hedge against adverse price movements or to speculate on price movements with limited risk.
Example of Risk Reversal
Bullish Scenario:
- Asset: Stock XYZ
- Current Price: $100
- Bullish Risk Reversal Structure:
- Buy 105 Call (OTM)
- Sell 95 Put (OTM)
If Stock XYZ rises above $105, the call option provides gains. If it falls below $95, the investor is obligated to buy shares at $95, capping the downside.
Bearish Scenario:
- Asset: Stock XYZ
- Current Price: $100
- Bearish Risk Reversal Structure:
- Sell 105 Call (OTM)
- Buy 95 Put (OTM)
If Stock XYZ falls below $95, the put option provides gains. If it rises above $105, the investor is obligated to sell shares at $105, capping the upside.
Applicability in Financial Markets
Risk reversals are widely used in various financial markets to hedge exposure to potential price changes. They can help manage risk in portfolios, especially in volatile markets, and are commonly utilized by institutional investors and traders.
Historical Context and Comparisons
Historically, risk reversal strategies have been employed during times of market turbulence to hedge portfolios against adverse price movements. Comparing risk reversals to other strategies such as straddles or strangles, risk reversals often have the advantage of lower initial cost due to the offsetting premiums of the bought and sold options.
Related Terms
- Straddle: An options strategy that involves buying a call and a put option with the same strike price and expiration date.
- Strangle: Similar to a straddle but uses out-of-the-money options for potentially lower initial cost and different risk/reward profile.
