About the Bear Put Spread

The calculator opens with a bear put spread in the nearest expiration: one at-the-money put bought and one put at the next lower strike sold.

The spread is a net debit position that profits when the stock falls. At expiration the most it can make is the distance between the strikes minus the debit, reached with the stock at or below the lower strike; the most it can lose is the debit, with the stock at or above the higher strike. The breakeven is the higher strike minus the debit.

Change the symbol, strikes, expirations or quantities, or add legs: the calculator takes up to eight option contracts and one stock position. To find candidates, use the Bear Put Spreads Screener: its chart icon opens this calculator with the selected position.
