Introduction
A risk reversal is an options strategy that combines a long out-of-the-money call with a short out-of-the-money put (or the reverse), creating a position with directional exposure similar to holding the underlying stock. It is primarily used by traders who want synthetic stock exposure without paying full price for shares, or by professionals hedging an existing position.
Understanding risk reversals matters for any options trader because the same concept — the skew between put and call implied volatility at different strikes — also affects how iron condors and other income strategies are priced.
How a Risk Reversal Works
A standard (bullish) risk reversal consists of:
- Buy an OTM call (right to buy at a higher price)
- Sell an OTM put (obligation to buy at a lower price)
Both options share the same expiration date but different strikes. The short put premium typically offsets part or all of the long call cost, making the structure low-cost or even a net credit.
Payoff at Expiration
| Scenario | Outcome |
|---|---|
| Underlying rises above call strike | Profit (similar to being long the stock) |
| Underlying stays between the two strikes | Both options expire worthless, minimal P&L |
| Underlying falls below put strike | Loss (similar to being short a put, can be significant) |
The strategy has unlimited upside (from the long call) and significant downside risk (from the short put). This is not a defined-risk structure — a key difference from iron condors.
Why Traders Use Risk Reversals
1. Synthetic Long Exposure Without Capital Commitment
Instead of buying 100 shares, a trader can buy a call and sell a put to simulate the same directional payoff at a fraction of the capital requirement. This is common in institutional trading where capital efficiency matters.
2. Hedging an Existing Position
A trader who is long a stock but wants partial downside protection can sell an OTM call (capping upside) and buy an OTM put. This is a bearish risk reversal — sometimes called a collar.
3. Trading Volatility Skew
In options markets, puts and calls at the same distance from the current price often trade at different implied volatilities. This gap is called volatility skew. Risk reversals are used to express a view on whether that skew is too wide or too narrow.
For example, if put implied volatility is significantly higher than call implied volatility (as is often the case in equity index options), a trader might sell the expensive put and buy the cheaper call.
Risk Reversal vs. Iron Condor: A Key Contrast
Risk reversals and iron condors represent two different philosophies of options trading.
| Dimension | Risk Reversal | Iron Condor |
|---|---|---|
| Directional? | Yes (bullish or bearish) | No (range-bound) |
| Risk Profile | Undefined (short put exposure) | Fully defined |
| Income? | Not an income strategy | Yes, premium-collecting |
| Use Case | Synthetic stock, hedging, skew trading | Monthly income, systematic premium selling |
Iron condors — the strategy used by Tradematic — are specifically designed to avoid directional risk and to collect premium from both sides of the market with a known maximum loss.

What Is Volatility Skew and Why Does It Matter?
Volatility skew refers to the difference in implied volatility between OTM puts and OTM calls. In US equity markets, OTM puts almost always trade at higher implied volatility than equidistant OTM calls. This reflects market demand for downside protection.
Risk reversals are one of the most direct ways to measure and trade this skew. A positive risk reversal value means calls are more expensive than puts. A negative value (more common in equities) means puts are more expensive.
The CBOE publishes data on options pricing and volatility products that help traders understand skew dynamics across major indexes.
Is a Risk Reversal Right for You?
Risk reversals suit traders who:
- Want leveraged directional exposure with reduced capital outlay
- Are comfortable with significant downside if the underlying falls sharply
- Understand that the short put creates an obligation to buy the underlying at the put strike
They are not appropriate for:
- Traders focused on income generation
- Traders who need defined maximum risk
- Accounts where large drawdowns cannot be absorbed
For income-focused traders, defined-risk strategies like iron condors offer more predictable risk/reward profiles. See risk vs reward in options trading for a broader comparison.
Frequently Asked Questions
What is a risk reversal in simple terms? A risk reversal is buying an out-of-the-money call and selling an out-of-the-money put at the same expiration — or the reverse for a bearish view. It creates a position that behaves like owning the underlying stock, without the full capital requirement.
Is a risk reversal a defined-risk strategy? No. The short put leg creates theoretically large losses if the underlying drops significantly. This is in contrast to an iron condor, which has a defined maximum loss from the start.
What is the difference between a risk reversal and a collar? A collar (also called a protective collar) is a bearish risk reversal used to hedge a long stock position: you sell an OTM call and buy an OTM put. The terminology varies by context — the structure is the same, the purpose differs.
Why do risk reversals show negative skew in equity markets? Because investors routinely pay more for downside protection (puts) than for upside participation (calls). This consistent demand keeps OTM put implied volatility higher than OTM call implied volatility.
Do automated trading platforms like Tradematic use risk reversals? No. Tradematic is an automated iron condor trading platform using a defined-risk, non-directional strategy. Risk reversals are directional and undefined-risk — a different category of strategy entirely.
Conclusion
A risk reversal is a directional options structure used for synthetic exposure, hedging, or volatility skew trading. It offers capital efficiency but carries significant downside risk from the short put.
