Poor Man's Covered Call
Prerequisite strategies: you must have run a covered call through a real call-away and held a long call long enough to watch extrinsic value die, and you should read LEAPS and the diagonal spread first — this structure is one of each. Clear the Level 2 gate. Next in the tier: the Wheel, which expresses the same view from the credit side.
Why this structure exists
A covered call is a fine trade with one disqualifying feature for most UK retail accounts: the collateral. An ICE Futures Europe single-stock option confers rights over 1,000 shares, so covering one Tesco call means owning £4,800 of Tesco plus £24.00 of stamp duty reserve tax to get it — on a £25,000 account, a fifth of everything committed to one FTSE 100 name to earn £47.50 a month.
The poor man's covered call keeps the income leg and replaces the collateral with a deep in-the-money long-dated call. A one-year Tesco 400 call at 91.26p costs £912.61 and carries a delta of 0.813 — it moves like 813 shares while costing 18.95% of what 1,000 real shares cost, the same figure the Wheel page quotes when it prices this LEAP at 19.8% of the £4,600 a cash-secured put locks up. The substitution also changes the source of the safety: a covered call's floor is your shares, while here the worst case is fixed by construction at the £865.11 net debit, and nothing Tesco does adds to it.
Why not just write the covered call? Because you would be paying £3,909.99 more for the same £47.50 credit, and the return on capital falls from 4.89% to 0.93% a cycle. The counterweight is quantified rather than waved away: the LEAP receives no dividend, so you give up roughly £144.00 a year of Tesco income — against £146.62 the released capital earns for a year at a 3.75% Bank Rate. The capital efficiency is real. The free lunch is not, because what you have bought is a share substitute with an expiry date, and everything in the management section below exists because of that date.
Construction
| Leg | Buy / Sell | Quantity | Strike rule | Expiry rule | Target delta | Price |
|---|---|---|---|---|---|---|
| Long LEAP call | BUY (debit) | 1 contract = 1,000 shares (ICE UK); 100 (US) | Deep ITM, 15–20% below spot; extrinsic ≤ 15% of the premium | 300–450 days; replaced at 90 | 0.80–0.85 | 91.26p = £912.61 |
| Short monthly call | SELL (credit) | 1 contract, same size, earlier expiry | Above the long strike plus the LEAP's cost | The nearest monthly, 25–45 days | 0.20–0.30 | 4.75p = £47.50 |
| NET | Net debit | 1 diagonal | 400 / 500, Tesco spot 480p | 365 days / 29 days | +0.544 (544 shares) | 86.51p = £865.11 |
Same underlying, same contract size, long strike below the short strike, and — the condition that separates this from a vertical — the long leg must expire after the short leg: 20 August 2027 against 18 September 2026. Break that and the broker stops treating it as a spread. Four inequalities before the order goes in:
Formulas: max loss = LEAP debit + opening commissions − credits collected, realised only if Tesco is at or below 400p on 20 August 2027. Max profit per cycle = LEAP mark at the short expiry − LEAP debit + credit − commissions, maximised at exactly the short strike. Breakeven at the short expiry solves LEAP(336 days) = net debit + costs; at the LEAP's own expiry it is 400p + 86.79p = 486.79p. Premiums are Black–Scholes at 22% implied volatility, 4% rates and a 3.0% dividend yield — the Wheel page's inputs, which reproduce its 91.26p LEAP exactly.
Two lines, two dates, and the gap between them is the trade. The solid line is where you will actually meet this position in 29 days, with 336 days of LEAP still alive: it never reaches the −£867.91 floor, because the LEAP still has value, and it peaks at the short strike rather than plateauing past it. Only the dashed line, a year later, shows the maximum loss. Read the right-hand side carefully: above 500p the solid line falls, at about £1.30 for every penny Tesco adds, because the short call loses a penny for every penny the LEAP gains 0.86 of. That drift is the price of the income, and it is why the peak is a target rather than a plateau.
Entry criteria
| Gate | Rule | Reason |
|---|---|---|
| IV rank / IV percentile | IVR below 25 to open. At IVR 30 or above run the Wheel or a covered call instead; between 25 and 30, do neither | Net vega is +£6.99 a point: you are a net buyer of volatility, and you buy a year of it in one payment. Open at 30% implied, watch it revert to 22% with Tesco unchanged, and the LEAP alone gives back £101.29 — 2.1 cycles of credit for a move you were never paid to carry |
| LEAP delta and extrinsic | 0.80–0.85 delta; extrinsic ≤ 15% of the premium | 0.813 and 12.3% here. The extrinsic is rent: £112.61, or 2.4 short-call credits to recover before the trade is even |
| LEAP days to expiry | 300–450 at entry; replaced at 90 | 88.7% of the £112.61 you paid for time has burned by 90 DTE, leaving only £12.73 to lose — which is why the roll is cheap then and dear later |
| Short strike | Above the long strike plus the LEAP's cost; 0.20–0.30 delta | 500p against a 491.26p floor. Those 8.74p are the entire guarantee that being called away is not a booked loss |
| Short call DTE | The nearest monthly inside 25–45 days | ICE UK series are monthly only. On 20 August the choice is 29 days or 57 — there is no 35-day series to pick |
| Liquidity | Short leg spread ≤ 10% of mid, open interest ≥ 100; on the LEAP nothing wider than 5% of mid each way | 5% each way on a £912.61 LEAP is £91.26 round-trip — 32.6× the commission, 1.9 cycles of credit spent before you start |
| Underlying | A share you would hold for two years, whose dividend you can afford to forgo | The LEAP holder receives nothing. Tesco's roughly 3% is £144.00 a year handed to whoever owns the actual shares |
| Event calendar | No results inside the short call's window; ex-dividend dates permitted but priced as early-assignment risk | Tesco's interim went ex on 9 October 2026 at 4.80p — £48.00 on 1,000 shares, and the trigger for the hazard below |
Do not enter if: IV rank is 30 or above — implied volatility is telling you to sell a year of premium, not buy one, and the right structures there are the Wheel and the covered call; the LEAP's delta is below 0.80 or its extrinsic exceeds 15% of the premium; the short strike you want sits below the long strike plus the LEAP's cost; you cannot fund a replacement LEAP in nine months' time; you are in a cash account, where the order is rejected before it reaches the exchange; or you actually need the dividend.
Debit or credit: the same view, two structures
"Mildly bullish, and I want to be paid while I wait" has two expressions, and IV rank picks between them rather than preference. This structure is the debit version: buy a year of delta, rent out a month of it. The covered call and the Wheel are the credit versions: own or agree to own the shares, and sell premium against them.
| Poor man's covered call (debit) — this page | Covered call (collateralised credit) | |
|---|---|---|
| Legs on Tesco at 480p | Buy Aug-27 400 call 91.26p, sell Sep-26 500 call 4.75p | Buy 1,000 shares at 480p, sell the same 500 call 4.75p |
| Capital committed | £914.01 (LEAP + commission) | £4,824.00 (shares + 0.5% SDRT) |
| Max loss | £867.91, fixed by construction | £4,779.30 if Tesco goes to zero |
| Max profit per cycle | £202.90 at exactly 500p | £220.70 if called away at 500p |
| Breakeven | 475.79p at the short expiry — Tesco may fall 0.9% | 477.93p — Tesco may fall 0.4% |
| Return on capital, one credit | 4.89% | 0.93% — the same £47.50 on 5.28× the capital |
| Dividend | None. £144.00 a year forgone | Roughly £144.00 a year received |
| If Tesco falls to 420p by 18 September | −£406.61 | −£579.30 — the LEAP version loses 70.2% as much |
| Use it when | IV rank below 25 | IV rank 30 or above, or you want the income |
| Day-one taxable gain | £47.50 (short call granted); the £912.61 LEAP gives no relief yet | £47.50 (short call granted); the shares' cost is already fixed |
Read the last four rows together, because they are the trade. The debit version wins on capital by 5.28× and on drawdown by roughly 30%, loses the dividend almost exactly to the interest on the capital it releases, and adds one thing the covered call does not have: a date at which the position ends whether you are ready or not. The Wheel sits further along the same credit axis — £4,600 of collateral for £94.70 a turn — and its gate, sell above IVR 30, is the mirror image of this one.
Greeks at entry and how they evolve
| Greek (net, per contract) | Entry: 29 / 365 DTE, 480p | 15 DTE, unchanged | 7 DTE, unchanged | +1 SD (510p, IV 20%) | −1 SD (450p, IV 26%) |
|---|---|---|---|---|---|
| Delta (share-equivalents) | +544 | +629 | +726 | +194 | +689 |
| Gamma (shares per 1p move) | −8.8 | −10.3 | −9.1 | −15.4 | +0.3 |
| Theta (£ per day) | +£1.37 | +£1.59 | +£1.40 | +£2.27 | −£0.07 |
| Vega (£ per vol point) | +£6.99 | +£8.47 | +£9.77 | +£3.82 | +£13.52 |
| Position P&L | −£2.71 | +£18.08 | +£30.58 | +£135.44 | −£140.98 |
Black–Scholes at 22% implied volatility unless stated, 4% rates, 3.0% dividend yield, per one 1,000-share ICE contract; the LEAP's DTE falls in step with the short leg's. Standalone, the LEAP carries +£11.45 of vega and −£0.35 a day of theta; the short call carries −£4.46 and +£1.72. The entry P&L is the £2.80 of opening commission less £0.09, the short leg being sold on the 4.75p tick against a 4.74p model price.
Delta decides this trade, and the +1 SD column is the reason. A rally to 510p is the outcome you wanted, and it takes net delta from 544 share-equivalents to 194: the LEAP's delta rises to 0.891 while the short call's races from 0.269 to 0.697 and eats the difference. The position stops participating in the move at precisely the moment the move arrives. That is not a defect — it is what you were paid £47.50 for — but it is the fact that separates this from stock replacement, and anyone who has not internalised it will hold through the peak and watch a winner drift back.
The character flip is a gamma event in the last three weeks. With Tesco sitting on the 500p strike, the short call's gamma rises from 15.1 share-equivalents per penny at 21 days to 40.0 at 3 days, a 2.65× increase, while the LEAP's stays pinned at 1.8 — a year-dated option barely notices a week. Net gamma goes from −13.3 to −38.2, so a 10p overnight move at 3 DTE swings net delta from +348 to +28 share-equivalents: a 321-share lurch you cannot hedge, against 128 at 21 DTE. Holding to expiry runs that risk for the last £6.30 of a £47.50 credit. It is a gamma decision, not a patience one, and the answer at this tier is no.
Tesco at 480p, one LEAP and the first monthly call, IV rank 18
Tesco (TSCO) traded around 480p in August 2026, inside a 52-week range of 406.90p to 510.40p, with a forward dividend yield near 3%. An ICE Futures Europe UK single-stock option is rights over 1,000 shares, physically delivered, American style, quoted in pence per share and ticking in 0.25p. One penny of option price is £10 of contract value.
Step 1 — Thursday 20 August 2026. Buy 1 × TSCO 20 August 2027 400 call.
Step 2 — the same day. Sell 1 × TSCO 18 September 2026 500 call, 29 days. The nearest monthly; the October series is 57 days away and outside the window.
Base case — 18 September 2026, Tesco 490p. The short call expires worthless and the LEAP has 336 days left. Its own delta has risen to 0.843, which is why repricing beats multiplying the entry delta by the move.
Favourable case — Tesco 510p, one standard deviation up. The good outcome, and the one that teaches the ceiling.
Adverse case — Tesco 450p, one standard deviation down. The branch that decides whether you understood what you bought.
That last line is the drawdown bind, and no management removes it: after a one-standard-deviation fall the only legal strike pays 22.8% of the first cycle's credit, where a covered call could write against its shares at any strike above base cost. Push further — Tesco 400p — and the LEAP marks 34.37p, the position is −£524.22 and delta has collapsed to 0.544. The −£432.56 stop fired on the way down at 415.8p, where delta was 0.613, within 3p of the 0.60 floor at which a share substitute has stopped substituting.
On a US chain instead — often the realistic route, since ICE UK LEAP series are thin and a US contract is 100 shares — the gain is still computed in sterling at the spot rate on each disposal date. A $45.00 LEAP on 100 shares costs $4,500, or £3,320.54 at GBP/USD 1.3552. Close it for $6,200 with the rate at 1.4000 and the proceeds are £4,428.57: a 37.8% dollar gain, but a chargeable gain of £1,108.03 against the £1,254.43 an unchanged rate would have given — £146.40 of currency, before the conversion spread, on every leg of every cycle.
This is a single, hand-picked, favourable scenario. It is not a typical or expected outcome. Every premium is modelled from Black–Scholes at the stated inputs rather than taken from a live chain, and real ICE UK quotes on a one-year series are materially wider. Past performance, including any illustrative example shown here, is not a reliable indicator of future results.
Management and adjustment
| Trigger | Diagnosis | Action | Do NOT do this |
|---|---|---|---|
| Short call tested, more than 21 DTE left | Working as designed — the LEAP gains more than the short leg loses | Nothing. At 510p at the short expiry you are +£189.95 with the short call £52.50 under water | Buy back the short call alone to "let the LEAP run". That converts a defined structure into an unhedged long call at the worst price |
| Short call in the money inside 21 DTE | Gamma, not direction — net gamma has trebled since entry | Roll out at the same strike for a credit: at 505p with 10 days left, buying back the September 500 at 10.14p and selling the October 500 at 17.10p is a +£66.72 credit | Roll up and out to the 520 — at 505p that is a £20.46 net debit, and this structure is never defended with a debit |
| Ex-dividend date inside the short window with the call ITM | Once extrinsic falls below the dividend, exercising early is rational for the holder | Close the short call the business day before the ex-date. At 505p with 7 days left it carries 3.98p of extrinsic against Tesco's 4.80p interim — assume assignment | Leave it and hope. You find out from the overnight statement, short 1,000 shares over the ex-date and owing the £48.00 dividend |
| Assigned early on the short call | You are short 1,000 Tesco shares and long a 400 call, not shares | Buy the shares back in the market and keep the LEAP, or close the whole structure | Exercise the LEAP to deliver. At 510p that throws away £57.87 of extrinsic and adds £20.00 of SDRT on the strike consideration |
| IV rank expands after entry | A vega gain you were not paid to have | Hold, and sell the next short call into the richer premium. Net vega +£6.99 a point makes an 8-point expansion worth +£55.92 | Close the LEAP to bank the volatility. The directional thesis has not changed and you would pay the spread twice |
| IV rank collapses after entry | The structural risk of a long-vega debit trade, and the reason for the IVR-below-25 gate | Hold while the LEAP's delta is 0.80 or better. An 8-point collapse costs £55.92, about one cycle's credit — recoverable, not fatal | Sell a closer short call to "make it back". That breaches the strike inequality and turns a survivable vega loss into a guaranteed assignment loss |
| Tesco below the 400p LEAP strike | The share substitute has stopped substituting: delta 0.544 and falling | Close everything. At 400p at the short expiry the position is −£524.22 | Roll the LEAP down. You would pay a fresh debit to restart a losing trade with less time |
| LEAP inside 90 days to expiry | Time-structure risk, not price risk | Close it and buy the next one. Only £12.73 of extrinsic remains, so the sale is efficient now | Hold it to expiry to save the roll cost. At 440p a 90-day 400 call is worth £155.62 less than a 365-day one — the optionality is worth most exactly when you need it |
ROLL WHEN the short call is in the money at or inside 21 days to expiry and the roll collects a net credit. ROLL TO the next monthly at the same strike or higher, as one order, always to an expiry before the LEAP's. Rolling out at the same 500 strike at Tesco 505p pays £66.72; rolling up and out to the 520 at that moment costs £20.46 — arithmetic, not judgement.
DO NOT ROLL past the LEAP's expiry. The moment the short call outlives the long one the broker stops offsetting them, and what you hold is an uncovered short call needing a permission you do not have at this tier — the platform will reject the order or margin it punitively. Do not roll for a net debit either: a debit roll on a losing short leg lifts the maximum loss above the number you agreed to before entry, the only number in this structure that was ever guaranteed.
THE CORRECT ACTION IS TO CLOSE, NOT ROLL, when Tesco is below the 400p LEAP strike; when the −£432.56 stop has fired; when the LEAP is inside 90 days; when the only available roll pays a debit; or when the thesis has been replaced by a hope that it comes back. A diagonal has an exit, not a defence — there is nothing left to hedge with once the long leg is the thing that is losing.
Exit rules
If all six are silent, do nothing and check the net delta tomorrow. That is the number worth watching between decisions: below 200 share-equivalents you are no longer running a bullish position, you are running a spread that has already made most of what it will make.
Margin and broker reality
A cash account cannot hold this trade, and that is where most UK first attempts die. The structure contains a granted call, and a cash account has no mechanism to carry one: Interactive Brokers permits only limited purchase and sale of options in a Cash account, so the order is rejected in the preview rather than at the exchange. You need a Margin account, for which IBKR's published minimum is USD 2,000 or equivalent. Hargreaves Lansdown, AJ Bell and Trading 212 offer no options at all, so this is an Interactive Brokers or Saxo trade.
What you do not need is uncovered-option permission. Because the long call sits at a lower strike, at the same size, and — the condition that matters here — expires after the short call, the broker margins the pair as a spread: the initial requirement is the net debit of £865.11, maintenance is nil, and buying power cannot fall further whatever Tesco does. That offset is conditional, not permanent: roll the short call beyond 20 August 2027 and it vanishes overnight. Enter both legs as a single diagonal order, because legging in leaves you briefly naked.
Then treat the ICE bid-ask as a margin-equivalent cost, since on a one-year series it is the largest number on this page after the debit itself. Five per cent of mid each way on the LEAP is £91.26 round-trip — 32.6× the commission, 1.9 short-call credits — and UK LEAP series often quote wider with open interest in single figures. That is the honest case for taking the structure to a US chain, where a contract is 100 shares and quotes are tight, and paying the FX conversion and the £146.40-style currency exposure instead. Neither answer is free; one of the costs is simply visible.
LEAP cost < strike width + credits collected, then subtract SDRT and both commissions before you believe it. If the only strike that satisfies it pays too little to bother with, the trade is the problem, not the strike.Portfolio fit
One contract contributes a net delta of +544 share-equivalents — £2,611.20 of Tesco exposure carried on £867.91 of risk, or £3.01 of exposure per pound at risk, against £1.00 for the covered call that owns the shares. That leverage is the point and the danger in one number. Net vega is +£6.99 a point, so unlike a book of verticals this is genuinely a long-volatility book: four of these carry +£27.96 a point, and a broad eight-point contraction costs £223.68 with every underlying sitting where you left it.
Sizing is where this structure argues with the tier. At the strict 2% rule a £867.91 maximum loss needs £43,396 of account, more than the £10,000 to £25,000 Level 2 assumes. Two defensible answers: size on the −£432.56 stop instead, which needs £21,628 and is honest only if you actually take the stop; or accept that on a £4.80 ICE name this is a one-contract position in a £25,000 account. Four contracts would risk £3,471.65 (13.9% of capital) and use £3,460.45 of buying power (13.8%), inside the 25% cap — but carry 2,176 share-equivalents of delta and that £27.96 of vega, so the binding constraint is correlation, not margin. Four on four names is a book; four on one is a leveraged bet with extra commission.
What to trade instead
Simpler, from the tier below: the covered call. It costs £3,909.99 more and returns 0.93% a cycle instead of 4.89% — but it pays roughly £144.00 a year of dividend, needs no margin account, has no expiry to manage, generates half the CGT events and cannot be undone by a volatility contraction. Take it whenever IV rank is 30 or better, or whenever you want the shares.
Sideways, at this tier: the Wheel is the credit expression of the same view above IVR 30; the diagonal spread is this structure with a shallower long leg, cheaper and much less like stock; the calendar spread is what to build if the view is about time rather than direction.
More precise, from elsewhere in this tier: a plain LEAPS position removes the ceiling entirely — no short call, no assignment risk, no monthly grant-date gain — at the cost of £570.00 a year of credit that pays for the LEAP's extrinsic twice over. If the last three cycles have all been rolls, that is the trade the market is asking for.
Risk statement
Listed options are complex instruments and most retail directional positions lose money. This is educational material about mechanics, margin and UK tax treatment, not a recommendation to trade Tesco or anything else, and it takes no account of your circumstances. Every premium here is modelled rather than quoted. If your trading becomes frequent enough to raise the investor-versus-trader question, that is one for a qualified adviser.
