Everything above is the idea. This is the position — the lines you would actually send to a broker.
| Leg | Action | Qty | Expiry | DTE | Strike | Delta | Price |
|---|---|---|---|---|---|---|---|
| 1 | Sell to open | -1 | 16 Oct 26 | 45 | 105 Call | -0.32 (32Δ) | $1.77 |
| 2 | Buy to open | +1 | 1 Sep 27 | 365 | 80 Call | +0.88 (88Δ) | $24.78 |
| Net | Debit | 1 position | 16 Oct 26 | 45 | — | +0.56 | $23.00 |
BUY +1 DIAGONAL XYZ 16 OCT 26/1 SEP 27 80/105 CALL @ 23.00 DEBIT
Bull
makes the claim
Same shape as a covered call for a quarter of the money. The rest of the capital sits in the account doing something else. Anyone who tells you to buy a hundred shares to sell one call is ignoring the cost of the shares.
Bear
doubts it
You have taken the same position and added an expiry date, a spread to cross, no dividend, and leverage. Every one of those is a cost. The trade looks identical on a payoff chart and behaves differently on every day that is not expiry day.
Ferret
settles it
The comparison is not the payoff shape, it is the return on the capital actually committed, across a long enough period to include a drawdown. That is measurable, and it is the test that would settle whether the substitution is worth it.
The poor man's covered call on XYZ at $100 · 25% volatility · 4% rate · 45 days. Priced from the model, not written by hand.
| At expiry | |
|---|---|
| Debit paid | $2,300 |
| Maximum profit | $568 |
| Maximum loss | $-2,300 |
| Breakeven | $98.70 |
The chart above is the shape at expiry. It puts the bend right next to the money, which makes the trade look like it is already on the edge. It is not — here is the day you open it.
The same structure set up at 30Δ · 45 days · credit $2,328. The shaded band is the room between the stock and the strike you sold.
| On day one | At expiry | |
|---|---|---|
| Stock at $106 (the strike you sold) | $294 | $634 |
| Stock unchanged at $100 | $0 | $88 |
Two dials on the short leg, plus the one that defines the structure: how deep and how far out the long call is. The panels move the short tenor.
| Days | Short strike | Away from spot | Credit | Max loss | Risk : reward |
|---|---|---|---|---|---|
| 7 | 102 | -2.0% | $2,361 | $-2,361 | — |
| 21 | 104 | -4.0% | $2,344 | $-2,344 | — |
| 45 | 106 | -6.0% | $2,328 | $-2,328 | — |
| 90 | 109 | -9.0% | $2,327 | $-2,327 | — |
| Delta | Short strike | Away from spot | Credit | Max loss | Risk : reward |
|---|---|---|---|---|---|
| 40Δ | 103 | -3.0% | $2,234 | $-2,234 | — |
| 25Δ | 107 | -7.0% | $2,352 | $-2,352 | — |
| 15Δ | 110 | -10.0% | $2,406 | $-2,406 | — |
How deep the long call sits is not a preference. It decides whether this behaves like stock or like a bet.
| Days left | Delta | Gamma | Theta / day | Vega | Rho |
|---|---|---|---|---|---|
| 45 | +55.6 | -3.30 | $+2.47 | $+7.32 | $+59.49 |
| 21 | +65.7 | -4.23 | $+3.17 | $+11.54 | $+58.55 |
| 7 | +80.2 | -3.70 | $+2.55 | $+15.94 | $+57.61 |
The position at entry — stock $100 · 25% volatility. Per contract, from the model.
This is the part that decides whether the strategy works, and it is almost never put plainly.
You cannot be paid theta without being short gamma. They are not two features of the trade. They are the rent and the risk on one lease.
| Days left | Delta | Gamma | Theta / day | Vega | Rho |

| Days left | Delta | Gamma | Theta / day | Vega | Rho |

| 7 | +51.0 | -10.15 | $+9.11 | $+9.60 | $+59.59 |
The trap is treating the long call as though it were shares.
Shares do not expire, do not decay, and pay dividends. The call you substituted does none of those things.
How this shows up in our tests — pending. No result has been published on this structure yet.
