Risk Reversal (Bearish)
A bearish risk reversal buys a put and sells a call for a low-cost bearish bet. Learn how it works, why it is often free, and the upside risk it carries.
A bearish risk reversal buys an out-of-the-money put and sells an out-of-the-money call, creating a low-cost bearish bet. The premium collected from the sold call helps pay for the put, so the trade often costs little or nothing to enter.
It is the mirror of the bullish risk reversal, and a synthetic short built with out-of-the-money strikes. Let me show you how it works.
Buy the Put, Sell the Call
A bearish risk reversal funds a downside bet with an upside obligation. You buy a put below the current price, betting the stock falls, and pay for it by selling a call above the current price, collecting premium. If the two premiums roughly match, the position is close to free.
The result is a bearish trade with a distinctive shape. If the stock falls, your put gains. If it stays flat between the strikes, both options expire worthless and you paid almost nothing. If it rises above your short call, you take losses like a short seller would. You financed downside protection or a bearish bet by selling away your upside.
Watch It Work
Apple is at $200 and you are bearish. You build a bearish risk reversal:
- Buy the $190 put for $4 a share
- Sell the $210 call for $3 a share
- Net cost: $1 a share, or just $100
You are positioned bearish for almost nothing.
Apple falls to $170. Your $190 put is worth $20 a share, or $2,000, while the sold call expires worthless. You keep the gain, minus the tiny cost.
Apple sits at $200. Both options expire worthless. You are out only the $100 net cost. A quiet stock barely costs you anything.
Apple rallies to $230. The $210 call you sold is now worth $20 a share against you, a $2,000 loss, just as a short seller would feel above $210. That upside obligation is the price of the cheap downside bet.
Cost, Risk, and Uses
A bearish risk reversal is a low-cost way to bet down or hedge a long position, with an important catch.
Low cost, real risk. The appeal is a cheap or free bearish position. The danger is the sold call, which gives you open-ended, short-like losses if the stock rallies hard. This is not a defined-risk trade; above the call strike it behaves like being short the stock.
A hedging use. Run against a stock you own, a bearish risk reversal is exactly a collar: the bought put protects your shares and the sold call pays for it. Standing alone, without the stock, it is a leveraged bearish bet instead.
Skew works against it. Because volatility skew tends to make out-of-the-money puts richer than calls, the put you buy is often pricier than the call you sell, so a bearish risk reversal is a bit less likely to be free than its bullish twin. Its mirror is the bullish risk reversal.
- A bearish risk reversal buys a put and sells a call, both out of the money.
- The sold call funds the put, so it is often cheap or free.
- It carries open-ended upside risk if the stock rallies.
- Against stock you own, it becomes a protective collar.

Bottom Line
A bearish risk reversal finances a downside bet with an upside obligation: buy a put, sell a call, and often pay almost nothing. It is a low-cost way to bet a stock falls, or, against shares you own, a ready-made collar.
The cost appears if you are wrong. The sold call means a sharp rally hurts like a short position, with open-ended risk above the call strike. Use it when you are genuinely bearish, or as protection on a holding, and respect the upside you gave away.
Keep going: its bullish mirror is the risk reversal, it is a synthetic short with wider strikes, and against stock it is a collar.
