A bear put spread is a limited-risk, limited-reward bearish options strategy. You buy a put at a higher strike and sell a put at a lower strike—both with the same expiration. The premium received from the sold put reduces the net cost of the trade, lowering breakeven and making the strategy more capital-efficient than buying a naked put.
The maximum profit on a bear put spread equals the spread width minus the net debit, realized when the stock closes at or below the lower strike at expiration. Maximum loss is the net debit paid—what you spend to enter the position. This defined risk profile makes bear put spreads useful for hedging long stock positions or expressing a moderate bearish view with controlled downside.
Strike selection typically involves buying an ATM or slightly ITM put and selling a put 5-10 points lower. This creates a favorable risk/reward ratio with a probability of full profit around 30-45%. Traders expecting a large move prefer wider spreads; those expecting a moderate decline prefer narrower spreads that cost less relative to the potential gain.
Bear put spreads are debit strategies, meaning time decay works against the position. Holding too long without the stock moving allows theta to erode the position's value. Most traders target a 45-60 day expiration cycle and close the trade at 50-75% of maximum profit rather than waiting for full payout.
One important use case for bear put spreads is portfolio hedging. Rather than buying expensive naked puts, owning a bear put spread on an index ETF provides defined downside protection at a fraction of the cost. The trade-off is that the protection is capped at the lower strike—if the market crashes well below your lower strike, you collect only the maximum profit of the spread, not unlimited protection.
