A bear put spread is a bearish options strategy that combines a purchased put with a sold put at a lower strike price. Both options have the same underlying asset and expiration date. You pay a net debit to open the position, accepting a ceiling on profit in exchange for a lower upfront cost than buying the higher strike put alone.
The trade suits a forecast with a price target and a deadline. Expecting a stock to fall is not enough: the entry price, size of the decline and timing determine whether the spread makes money. The Options Industry Council’s bear put spread overview sets out this exchange between reduced cost and capped profit.
How a Bear Put Spread Is Structured
To establish one bear put spread, buy one put at the higher strike and sell one put at the lower strike. Use matching expiration dates, contract quantities and deliverables. Buying more puts than you sell, or mixing expiration dates, creates a different position.
The purchased put gives you the right to sell the underlying at the higher strike. The sold put creates an obligation to buy it at the lower strike if assigned. The premium received from the sale offsets part of the purchase price.
It is a debit spread because the premium paid exceeds the premium received. It belongs to the vertical options spread family, where the legs share an expiration but have different strikes.
The maximum loss on the intact options position is the opening debit, before costs. That does not mean the account can be ignored until expiration. Exercise or assignment can create share positions that require funding and active handling.
Bear Put Spread Example
Assume a hypothetical stock trades at $100. You expect it to decline over the next 45 days and enter the following position using options with the same expiration:
Buy one $100 put for $5.20 and sell one $95 put for $3.00.
The net debit is $2.20 per share: $5.20 paid minus $3.00 received. For this example, each contract represents 100 shares, making the opening payment $220. Standard stock option premiums are quoted per share, and a contract generally represents 100 shares; the SEC’s introduction to listed stock options describes this pricing convention. Check the deliverable rather than assuming every contract is standard.
The distance between the strikes is $5. At expiration, the higher strike put’s intrinsic value exceeds the lower strike put’s intrinsic value by no more than that amount. Your profit is this difference, multiplied by 100, minus the opening payment.
Maximum Loss, Maximum Profit and Break-Even
The calculations below exclude commissions, fees and any costs associated with share positions:
- Maximum loss: net debit × contract multiplier = $2.20 × 100 = $220.
- Maximum profit: (higher strike − lower strike − net debit) × multiplier = ($100 − $95 − $2.20) × 100 = $280.
- Break-even at expiration: higher strike − net debit = $100 − $2.20 = $97.80.
These are expiration calculations, not promises about the price available if you close early. The distinction matters when calculating an options spread’s break-even price: an expiration break-even is not a universal exit threshold.
Payoff at Different Expiration Prices
| Stock price at expiration | Long $100 put value | Short $95 put obligation | Net spread value | Profit or loss |
|---|---|---|---|---|
| $100 or above | $0 | $0 | $0 | −$220 |
| $99 | $100 | $0 | $100 | −$120 |
| $97.80 | $220 | $0 | $220 | $0 |
| $97 | $300 | $0 | $300 | +$80 |
| $95 | $500 | $0 | $500 | +$280 |
| $90 | $1,000 | $500 | $500 | +$280 |
The table shows the net option payoff, assuming exercise and assignment are handled correctly. Physical settlement can produce stock transactions rather than a single cash payment.
At $99, the bearish forecast was directionally correct, but the trade still lost $120. Below $95, further declines add nothing to the expiration profit: each extra dollar gained by the purchased put is offset by another dollar owed on the sold put.
Choosing Strikes and Expiration
Start with the expected stock price and the time needed to reach it. Then compare spreads whose payoff fits that forecast. Starting with the cheapest premium and inventing a forecast afterward gets the process backward.
The lower strike marks where the expiration payoff stops growing. In the example, $95 is the full payoff threshold. If your forecast is a decline only to $98, calculate the result at $98 rather than focusing on the advertised maximum profit.
Selling a put closer to the purchased strike generally brings in more premium and reduces the debit. It also narrows the payoff ceiling. Selling a put farther below the purchased strike leaves more room for profit, but contributes less premium toward the purchase. The relationship between strike width, risk and reward deserves attention before comparing headline prices.
Expiration should allow time for the expected move without treating extra time as free. Compare the actual debit and payoff across available dates. If the thesis depends on an earnings release, check that the announcement falls before expiration; an event after the options expire cannot rescue the position.
Position size should follow the amount you can afford to lose, not the attractive percentage return on one winning spread. Five spreads costing $220 each put $1,100 of premium at risk before costs.
Why Profit Before Expiration Can Differ
Before expiration, the spread trades at the difference between two option prices, not simply the difference between their intrinsic values. Both contracts may still contain time value.
Suppose you paid $2.20 and later close the spread for a net credit of $3.60. The profit is $140 per spread before costs: ($3.60 − $2.20) × 100. That calculation uses your actual transaction prices, not the expiration table.
Delta measures sensitivity to the underlying price. A bear put spread normally has negative net delta, so a falling stock generally helps. Gamma measures how that sensitivity changes. Neither number stays fixed as the stock moves.
Theta measures sensitivity to passing time, while vega measures sensitivity to implied volatility. These are model estimates rather than guaranteed daily changes, as reflected in the OIC’s explanation of volatility and the Greeks.
For a spread, assess both legs together. Their time and volatility exposures can partly offset, but not necessarily cancel. Avoid assuming that paying a debit means the position must lose the same amount of time value every day, or that a volatility increase must help by a predictable amount. Recheck the net exposure as prices change.
Entering and Closing the Spread
A combined spread order lets you express the trade as one package with a net price. At entry, the debit limit sets the most you will pay for that package. At exit, a credit limit sets the least you will accept. Cboe’s complex order documentation describes execution within a combined net price and leg ratio.
That is different from submitting two unrelated orders and hoping both fill favorably. Trading the legs separately creates an interval in which you hold only part of the intended position. A limit order controls the acceptable price; it does not guarantee a fill.
Judge the trade using executable prices, not just a midpoint displayed on screen. Paying $2.35 instead of $2.20 raises the example’s premium risk from $220 to $235 and cuts maximum profit from $280 to $265.
To close the spread, sell the purchased higher strike put and buy back the sold lower strike put. Closing only the purchased put leaves a short put obligation rather than the original capped payoff.
Before entry, decide what would justify an exit: reaching a stock price target, earning an acceptable profit, losing confidence in the forecast or approaching expiration. Closing and rolling an options spread are different decisions. Rolling realizes the existing result and opens another trade; it does not erase a loss.
Assignment and Expiration Risks
Early Assignment Can Create a Funding Obligation
A short American style put can be assigned before expiration. Assignment requires purchasing the underlying at the short strike, even when another option protects the position. The purchased put does not automatically close or exercise just because the short put is assigned. These separate obligations are addressed in FINRA’s guidance on assignment in options spreads.
In the example, assignment on the $95 put means buying 100 shares for $9,500. That purchase is not itself a $9,500 loss: you receive the shares and still hold the $100 put. Nevertheless, the funding requirement is very different from the original $220 debit.
Know how the account would handle that obligation before placing the trade. A small premium payment does not make settlement mechanics small.
Expiration Can Leave an Unwanted Stock Position
At a $96 expiration price, the $100 put is in the money and the $95 put is out of the money. If the long put is exercised and you do not own the underlying shares, it can create a short stock position. Near $95, uncertainty about assignment on the short put makes the resulting share exposure harder to predict.
Do not treat the closing stock price as proof that both legs will resolve as expected. Exercise decisions and price changes after regular trading can affect the outcome. Once protection expires or the legs stop offsetting one another, subsequent share losses can exceed the original debit.
Your broker may also liquidate expiring positions if the account cannot meet potential purchase or delivery obligations. The resulting execution can reduce profit or produce a loss, a risk covered in FINRA’s discussion of expiration day liquidation. Check the firm’s exercise deadlines and account procedures rather than relying on automatic handling.
When a Bear Put Spread Fits Better Than a Long Put
The spread makes sense when reducing the upfront debit matters more than retaining profit from every further decline.
Using the same hypothetical premiums, buying only the $100 put costs $520 and has an expiration break-even of $94.80. Adding the short $95 put reduces the payment to $220 and raises break-even to $97.80.
The price of that improvement appears during a larger decline. At a $90 expiration price, the standalone put earns $480 before costs, while the spread earns $280. At $95, however, the standalone put loses $20 while the spread earns $280. Neither structure wins in every outcome.
Before entering, write down the expected price, deadline, acceptable debit and exit plan. Include all charges: a hypothetical $6 in total costs reduces the example’s maximum profit to $274. The useful question is not whether the spread looks cheap, but whether its payoff matches the move you expect and the loss you can accept.
Examples are hypothetical and educational, not recommendations to trade. Options can expire worthless and are not suitable for every investor.
