How do I roll the short call on a PMCC?

Rolling the short leg is the normal maintenance of this trade. It is also the fastest way to cap it below its own cost without noticing, because a roll that takes in a credit can still make the ceiling worse.

What rolling means here

A poor man's covered call is a long-dated call (a LEAPS) plus a short nearer-dated call sold against it, standing in for 100 shares. The long leg sits for a year. The short leg is what you keep replacing.

Rolling is two orders in one: buy back the short call you have, sell another. Three directions:

• Roll out — same strike, a later expiry.
• Roll up and out — a higher strike and a later expiry.
• Roll down and out — a lower strike and a later expiry.

A roll is a credit when the call you sell brings in more than the buy-back costs, and a debit when it costs more. A debit comes out of your pocket today and never comes back on its own.

The check to run after every roll

It all hangs off one line:

Net debit is everything you paid for the long call, minus every credit taken in and plus every debit paid, over the whole life of the trade.

Run it after every roll. If the answer is negative, the trade is capped at a loss — assignment on that short call locks the result there, however far the stock runs. Choosing the LEAPS strike covers the same check at the entry.

A worked example (hypothetical)

An illustration, not a trade idea.

Made-up company Meridian Grocers trades at $50.

• Buy a 14-month $40 call for $14.00: −$1,400.
• Sell a 30-day $55 call for $0.50: +$50.
• Net debit: $1,350. Width to the short strike: (55 − 40) × 100 = $1,500.
• Most this can make: $1,500 − $1,350 = +$150. Max loss: the $1,350.

Now the three rolls, each measured from that same starting point.

The legs behind each row, in the same order: buy back the $55 at $0.40 and sell next month's $55 at $1.60; buy back the $55 at $2.40 and sell next month's $60 at $0.80; buy back the $55 at $0.05 and sell next month's $45 at $1.25.

Read the first and third rows together. Both took in exactly $120. One raised the ceiling to $270. The other dropped it to minus $730. The credit told you nothing. The strike did all the work.

Why the down-and-out roll is the trap

That third row feels responsible. The stock fell, the old call is worthless, so you bring the strike closer to the money to collect something real. $120 in, same as the good roll.

Here is how it ends. The stock recovers to $50 by the new expiry. Your $45 call is in the money and gets assigned. You exercise the long call to deliver:

−$1,400 paid, +$50 first premium, −$5 buying back, +$125 new premium, −$4,000 exercising at $40, +$4,500 delivering at $45.

−$730. The same number the formula gave before you placed the roll.

You could instead buy 100 shares at $50 on the market to deliver and keep the long call, which is worth about $12.95 with twelve months left. That comes to −$435 — better by the long call's $295 of remaining time value, and the reason exercising to cover an assignment is almost always the expensive exit.

Either way it is a loss, on a stock that finished exactly where it started. Before the roll, the worst that assignment could do was pay you $150.

Why rolling up and out is not free either

The second row looks smart, and the ceiling arithmetic agrees: $490 beats $150. But look at the cost.

You paid $160 out of pocket, and you gave up a certainty: at $57 the $55 call was in the money, so letting it be assigned would have realised the +$150 ceiling, trade closed.

Now run the stock back down. It slides to $48 by the new expiry. The $60 call expires worthless. Your long call is worth about $11.25, against $1,510 now in the trade.

$1,125 − $1,510 = −$385.

A locked +$150 turned into −$385 on the screen. A $535 swing, and you spent $160 of cash to get it.

That is the honest shape of rolling up and out. It raises the ceiling and your break-even by the same money. It pays only if the stock keeps going, and it makes every flat or falling outcome worse.

So when should you roll?

That last row is the one people refuse. Collecting nothing for a month feels like failure. It is not — it is the month you did not sell your own recovery for $120. If the stock has fallen through the long strike, the stock fell below your LEAPS strike has the full set of choices.

Place a roll as a single order where your broker supports it, so you are never briefly uncovered. And use limit orders: far-dated contracts trade thinly.

Holding two legs at once needs a higher options permission level at most brokers than a plain covered call does. In Canada, writing calls and running spreads inside a TFSA or an RRSP depends on the broker and may not be allowed at all — check your broker's current options agreement before building a plan that assumes you can roll.

If the ceiling arithmetic is more bookkeeping than you want every month, that is a real answer. The wheel strategy on actual shares has no ceiling to blow, and the alternatives are mapped in option strategies beyond the wheel.

Your routine, in five lines

1. Before the roll, write down your current net debit.
2. Add every debit and subtract every credit the roll creates. That is the new net debit.
3. New ceiling = (new short strike − long strike) × 100 − new net debit.
4. If that is negative, do not place it. Pick a higher strike or sell nothing.
5. Log the new net debit somewhere you will find it next month. The options roll calculator will do the arithmetic, but only you can keep the running total.
