Bull Put Spread

Bull Put Spread starts from a simple idea: Sell a put and buy a lower-strike put. You collect a credit and want the shares to stay above the short strike. The construction is short one put, long one put at a lower strike, same expiry.

The sketch on this page uses a sample price of 50 and round teaching premiums, so you can see the shape. A live quote will use different strikes and a different debit or credit, and the picture before expiry is softer than the line at expiry because leftover time still has value.

Read Bull Put Spread as a finished bet on where price will be when the options expire, not as a forecast of every day in between. The credit is the most you can keep. A fall through the long strike leaves a loss equal to the strike gap minus the credit.

A bullish or sideways view that gets paid up front, with the long put cutting off the worst of a drop. Traders usually file it under Bullish Outlook. That label is a starting filter, not a promise that the trade will work.

It is a poor fit when your forecast needs a payoff this structure cannot deliver. If you need unlimited upside, do not choose a capped spread. If you cannot carry an open-ended loss, do not choose a naked or ratio position that still has an uncovered short option. Match the forecast to the shape on the chart before you match it to the name.

You own 1 45 put. You sold 1 55 put. There is no share leg, so the result comes only from the options.

Every option in the sample shares one expiry, so the line is the profit or loss if you hold to that date and the options are settled for their intrinsic value.

The sample is opened for a credit of 4 points. That credit is yours at the start only if the later outcome does not take it back.

The profit tops out at 4 pts in this sample. After price reaches the zone where every long option is as valuable as it can be against the shorts, a further move does not add profit.

That cap is the trade you accepted in exchange for a smaller debit or a credit. Bull Put Spread is the wrong tool if your forecast needs a much larger move than the distance between the strikes.

The worst expiry result in this sample is -6 pts. Both the long and short options have finished on the wrong side of that number, and the remaining loss is the net debit or the strike gap that the credit did not cover.

A capped loss is still a real loss. It is the amount you should be willing to spend or reserve before you open Bull Put Spread, not a figure to discover after the move.

In this sample the line crosses zero at 51. The gold dots sit on that zero line. The dashed line is only the sample spot of 50, not a target.

Each breakeven already includes the debit you paid or the credit you received. If you pay more than this sample, the profitable zone shrinks. If you receive a larger credit, the zone widens. Bull Put Spread should be judged from your fill, not from these round numbers.

Implied volatility does not point one way for every leg of Bull Put Spread. A long option gains from higher volatility and a short option loses, so the net mark depends on which strike is closer to the live price.

At expiry the argument ends. Volatility is gone and only the price relative to the strikes remains. Do not hold a volatility view into the final hour and expect it to survive settlement.

You collected premium in Bull Put Spread. If price stays inside the zone where the short options can expire worthless, that premium is the profit and time is how you earn it.

Time does not protect you from a move through the short strike. Decay is a benefit only while the price forecast remains intact.

The short leg is 1 55 put. Assignment can happen before expiry once that option is in the money, and it is more likely when it is deep in the money or when a dividend makes early exercise attractive.

If you are assigned, the long option does not automatically cancel the stock the same afternoon. You can wake up long or short shares for a day. Closing Bull Put Spread before expiry, instead of hoping both legs expire together, removes that weekend guess.

The credit is the most you can keep. A fall through the long strike leaves a loss equal to the strike gap minus the credit.

The sample breakeven sits at 51. Into the last day, decide whether you will close or hold. A short option that finishes near its strike can be assigned or not, and you may not know which until the next session. Bull Put Spread is easier to manage when that decision is made while the market is still open.
