Common Variations
The default setup above is one version of the bear put spread. Traders adjust strike placement to trade off cost, probability, and payout:
Wide bear put spread
Place the strikes far apart for a larger potential profit at the cost of a bigger net debit.
Key difference: Higher max profit and higher cost; behaves more like a standalone long put.
Best for: Traders with strong bearish conviction who still want defined risk.
Narrow, near-the-money bear put spread
Place both strikes close together and close to the current price for a cheaper, higher-probability trade.
Key difference: Lower cost and higher probability of some profit, but the maximum payout is smaller.
Best for: Traders who want defined risk on a modest, higher-confidence decline.
Frequently Asked Questions
Why use a bear put spread instead of just buying a put?
Comparisons
Selling the lower-strike put reduces the net cost and lowers the breakeven price versus a naked long put, in exchange for capping the maximum profit at the lower strike.
What happens if the stock finishes between the two strikes?
Setup
You keep the intrinsic value of the long put, but the short put expires worthless. Profit is prorated based on how far the stock finished below the higher strike.
Can I lose more than my initial debit?
Greeks & Risk
No. Both legs are defined at fixed strikes, so the maximum loss is capped at the net premium paid regardless of how far the stock rises.
When would early assignment on the short put matter?
Adjustments
If the stock falls sharply and the short put goes deep in-the-money, you could be assigned early and forced to buy shares — closing or rolling the spread avoids this risk.
