Price fell through my short put. What are my choices?

The stock has fallen through the put you sold. You have four choices. One of them costs you a debit today and raises your max loss above where it started, and it is the one most people pick.

Where you actually stand

The put you sold is in the money. The put you bought is still out of the money. The position shows red because the market now prices the spread closer to its full width.

Two facts change the mood. Your break-even is the short strike minus the credit you collected, not the strike itself. And your loss is still capped, as long as both legs are open on expiry day.

You have four real choices: close it, roll it down and out, roll it out in time at the same strikes, or do nothing. Each has a price today and a worst case later, and one of them ends up worse than the max loss you started with.

Where this trade sits among the others is mapped in option strategies beyond the wheel.

The trade, in numbers

(Hypothetical. An illustration, not a trade idea.)

Harbour Mills trades at $60. Thirty days out you sell a put credit spread:

• Sell the $55 put for $1.20
• Buy the $50 put for $0.40
• Net credit $0.80, so $80 in your account

The spread is $5 wide, so:

• Max gain: $80.
• Max loss: (5 × 100) − 80 = $420.
• Break-even: $55 − $0.80 = $54.20.

Eighteen days in, Harbour Mills has fallen to $54 on a weak quarter. Twelve days left. The $55 put is now $2.20 and the $50 put is $0.55, so the spread costs $1.65, or $165, to buy back.

Note where $54 sits: below the strike you sold, and just below your break-even. Expiry right here leaves $80 of credit minus $100 of intrinsic value on the short put, so −$20. Almost nothing. The red number on your screen is the spread's price, not its outcome.

The four choices, priced out

Each row, worked:

1. Close it. You collected $80 and pay $165 to get out. That is −$85, final, whatever Harbour Mills does next.

2. Roll down and out. Buy back the $55/$50 spread for $165, then sell next month's $50/$45 spread for $0.90, so $90.

• Cash today: −$165 + $90 = −$75. That is a debit. It does not matter that $90 is bigger than the $80 you first collected: $75 left your account today.
• Credit in hand across both trades: $80 − $165 + $90 = +$5. New max loss: (5 × 100) − 5 = $495.

Read that twice. You moved the strikes $5 lower and bought another month, and your worst case went from $420 to $495 while your best case went from $80 to $5.

3. Roll out, same strikes. Buy back this month's spread for $165, sell next month's $55/$50 spread for $2.10, so $210.

• Cash today: −$165 + $210 = +$45, a credit.
• Credit in hand: $80 − $165 + $210 = +$125.
• New max loss: 500 − 125 = $375.

This is the only roll here that improves both ends. The catch is that the short $55 put is still in the money and the strikes have not moved, so you have bought 30 more days of being wrong in the same place.

4. Do nothing. Hold to expiry and let the stock decide.

That last row is the one worth staring at. At $44 the short put loses $1,100 and the long put pays back $600. The net is $500, the full width, and the credit brings it to $420. The long leg is what makes a $16 drop cost the same as a $5 drop.

Which one most sellers take

Most people roll, and most of those roll down and out — choice 2. It feels active and responsible. The strikes move away from danger, the trade gets more time, and the screen stops showing a loss.

What it actually did was pay $75 to add $75 to the worst case, on a stock that was still falling.

Rolling down and out is right in one situation: when you would open that new $50/$45 spread today, at that size, for that credit, having never seen the first trade. If the honest answer is "no, I just don't want to book the $85", it is a bigger bet placed to avoid writing down a smaller one.

Choice 3 is the better technical roll when you still believe the level. Choice 1 is right most often, because $85 is a cheap loss and the capital goes back to work.

What happened next

Say the reader takes choice 2. (Still the same hypothetical.)

Harbour Mills keeps sliding. Next month it closes at $46, below both new strikes. The $50/$45 spread settles at its full width.

• Credit in hand: +$5.
• Spread settles: −$500.
• Final result: −$495.

Second route to the same number: max loss on a $5-wide spread holding $5 of credit is 500 − 5 = $495. They agree.

Closing on the day it was tested cost −$85. The roll cost −$495. The repair cost $410 more than the problem.

And it almost worked. If Harbour Mills had stopped at $51 instead of $46, the rolled spread would have expired worthless and the reader would have kept $5 and told the story as a save. Five dollars, for a month of carrying $495 of risk.

The rule to write before the next one

Pick the exit while you have no money on the line. Any of these is a real rule, and sellers commonly use one:

1. Close when the short strike is touched. Early and cheap. You will close some trades that would have recovered.
2. Close when the loss reaches the credit, or twice it. On an $80 credit that is out at −$80 or −$160, both far from $420.
3. Close at a set number of days to expiry, in or out of the money, so assignment and pin risk never enter the trade. The two things that go wrong at expiry are covered in credit spread expired between the strikes and credit spread assigned early.

Then one more rule, the one that makes the others hold: a roll is a new trade. Price it on its own merits, and only accept it for a credit. Rolling for a credit explains why that rule exists.

One account note. Multi-leg spreads need a higher approval level than the covered calls and cash-secured puts of the wheel strategy, and in Canada many brokers do not permit them in a TFSA or RRSP at all, so check before you plan a roll you cannot place.
