Date: July third, 2025
Value: TGT @ $104.59
Purchase one contract Aug 1st TGT $95 put @ $0.89Sell one contract Aug 1st TGT $100 put @ $1.93
Internet Credit score: $103
Right here, the dealer is risking $400 to make $100 probably.
The task danger is within the quick choice, the choice that was bought.
On this case, the sale of the August 1 $100-strike put choice is the leg that may end up in inventory task.
If Goal’s share value is under $100 at expiration, the dealer shall be assigned 100 TGT shares.
Because it so seems, on the finish of the session on expiration day, August 1st, TGT closed at $99.77, just below $100.
Subsequently, the subsequent day, the dealer finds that he has 100 shares of TGT inventory.
He was assigned (or obligated to purchase) the 100 shares on the strike value of $100/share.
Because the market value of TGT on the time was $99.77, he had misplaced $0.23/share or $23 from the task.
However keep in mind that he had obtained $103 in credit score firstly of the commerce.
Subsequently, he truly had a internet acquire of $80 within the commerce, minus any commissions and charges.
The quick and lengthy choices have expired and are now not in his account.
As a result of he now solely has inventory, he has the standard inventory danger.
There isn’t any extra credit score unfold.
A inventory and not using a cease loss is an undefined-risk place, with a danger graph that appears like this…
When a bull put credit score inventory expires, you might find yourself with inventory with limitless danger.
In concept, Goal inventory can go to zero, nevertheless unlikely, contemplating the variety of prospects seen in Goal shops.
Within the following instance, we see how a dealer can find yourself with a brief inventory place even earlier than expiration.
On Halloween, a dealer initiates an at-the-money bear name unfold for a directional commerce, anticipating Starbucks (SBUX) to go down in value.
Date: 10/31/2025
Value: SBUX @ $80.91
Promote one contract Nov 28 SBUX $80 name @ $3.06Buy one contract Nov 28 SBUX $85 name @ $1.11
Credit score: $195
From the chance graph, the commerce dangers about $300 to probably make $200.
It’s a defined-risk commerce that can’t lose greater than $305.
That is calculated by the width of the unfold minus the preliminary credit score obtained…
($80 – $85) x 100 – $195 = $305
On November 14th, the dealer will get an e-mail notification from his dealer that the quick $80 80-call choice has been assigned.
When the dealer sells the $80 name choice to a different celebration firstly of the commerce, the opposite celebration holding the choice has the best to train it to purchase SBUX at $80/share at any time.
On this case, they exercised that proper to accumulate 100 shares of SBUX at $80/share, which is now buying and selling at $86.44/share.

Clearly, SBUX has gone up in value (within the mistaken course that the dealer anticipated).
The value had gone above the quick strike value of $80 (which signifies that this feature is within the cash).
The danger graph now not seems to be just like the one above as a result of the $ 80 name choice is now not within the account.
The dealer was compelled to promote 100 shares of SBUX on the value of $80/share.
He’s now quick 100 shares (assuming he didn’t have already got 100 shares of SBUX).
He nonetheless has his $85 85-call lengthy choice, which has two extra weeks until expiration.
There isn’t any extra quick name choice.
The right danger graph now seems to be like this…
If the inventory goes down, he’ll revenue as a result of he’s quick 100 shares.
This revenue is uncapped as a result of SBUX can, in concept, go to zero, nevertheless unlikely that could be, given the variety of individuals consuming Starbucks espresso.
The dealer can, at this level, exit the commerce fully and be accomplished with it.
Let’s calculate the P&L if the dealer should purchase again 100 shares of SBUX the subsequent day at $86.30.
This closes the quick inventory place.
After which he sells the $85 name choice for $3.00 per share, or for $300.
Preliminary credit score for bear name unfold: $195
Assigned to promote 100 shares at $80/share: $8000
Purchase again 100 shares: -$8630
Promote to shut $85 name choice: $300
Internet P&L in commerce: -$135
The dealer should purchase again the inventory earlier than promoting the lengthy name, for the reason that lengthy name protects the dealer from loss if SBUX continues to rise.
Within the final instance, we noticed how the chance graph modifications as a bear name credit score unfold is early assigned.
Nevertheless, we will see from the ensuing danger graph that so long as the lengthy name has not expired, the chance of the commerce nonetheless stays at round $300 (the identical danger because the preliminary bear name unfold).
It’s because if SBUX is above $85 at expiration, the lengthy name will routinely purchase again the quick inventory at $85/share, closing out the quick place.
In the long run, it will be like…
Preliminary credit score for bear name unfold: $195
Assigned to promote 100 shares at $80/share: $8000
Purchase again 100 shares: -$8500
Internet P&L: -$305
