Date: July third, 2025
Worth: TGT @ $104.59
Purchase one contract Aug 1st TGT $95 put @ $0.89Sell one contract Aug 1st TGT $100 put @ $1.93
Web Credit score: $103
Right here, the dealer is risking $400 to make $100 doubtlessly.
The project threat is within the brief possibility, the choice that was bought.
On this case, the sale of the August 1 $100-strike put possibility is the leg that may end up in inventory project.
If Goal’s share value is beneath $100 at expiration, the dealer will likely 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, slightly below $100.
Due to this fact, 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 project.
However do not forget that he had obtained $103 in credit score at the beginning of the commerce.
Due to this fact, he truly had a internet acquire of $80 within the commerce, minus any commissions and charges.
The brief and lengthy choices have expired and are not in his account.
As a result of he now solely has inventory, he has the same old inventory threat.
There isn’t a extra credit score unfold.
A inventory with out a cease loss is an undefined-risk place, with a threat graph that appears like this…
When a bull put credit score inventory expires, you could find yourself with inventory with limitless threat.
In idea, Goal inventory can go to zero, nevertheless unlikely, contemplating the variety of clients 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
Worth: 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 doubtlessly 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 brief $80 80-call possibility has been assigned.
When the dealer sells the $80 name possibility to a different get together at the beginning of the commerce, the opposite get together holding the choice has the correct to train it to purchase SBUX at $80/share at any time.
On this case, they exercised that proper to amass 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 brief strike value of $80 (which implies that this selection is within the cash).
The threat graph not seems just like the one above as a result of the $ 80 name possibility is not within the account.
The dealer was pressured to promote 100 shares of SBUX on the value of $80/share.
He’s now brief 100 shares (assuming he didn’t have already got 100 shares of SBUX).
He nonetheless has his $85 85-call lengthy possibility, which has two extra weeks until expiration.
There isn’t a extra brief name possibility.
The proper threat graph now seems like this…
If the inventory goes down, he’ll revenue as a result of he’s brief 100 shares.
This revenue is uncapped as a result of SBUX can, in idea, go to zero, nevertheless unlikely that could be, given the variety of folks ingesting Starbucks espresso.
The dealer can, at this level, exit the commerce utterly and be achieved with it.
Let’s calculate the P&L if the dealer should buy again 100 shares of SBUX the subsequent day at $86.30.
This closes the brief inventory place.
After which he sells the $85 name possibility 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 possibility: $300
Web P&L in commerce: -$135
The dealer can 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.
Nonetheless, we are able to see from the ensuing threat graph that so long as the lengthy name has not expired, the chance of the commerce nonetheless stays at round $300 (the identical threat because the preliminary bear name unfold).
It’s because if SBUX is above $85 at expiration, the lengthy name will mechanically purchase again the brief inventory at $85/share, closing out the brief 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
Web P&L: -$305
For individuals who have by no means shorted a inventory, observe that there’s a stock-borrowing charge that varies by dealer.

However it may be extra important for hard-to-borrow shares.
