Defined-Risk Spreads — Verticals & Iron Condors

Summary

Vertical spreads and iron condors illustrate bounded expiration payoffs, with execution and assignment risks to consider.

Comparing expiration payoffs

A spread combines long and short options. Certain vertical spreads have bounded theoretical payoffs at expiration, unlike an uncovered short call. That comparison does not make spreads universally safe or suitable for beginners. TradeHQ does not execute options spreads; the examples below are worksheet exercises.

Bull call spread — a hypothetical example

Assume one standard 100-share contract per leg, the same expiration, a $180 long call costing $4 per share and a $185 short call receiving $2. The net debit is $200. With both legs resolved as the expiration payoff assumes, the maximum loss is $200 and the maximum gain is ($185 - $180) × 100 - $200 = $300, before costs. At a $182 expiration price, the $200 intrinsic value offsets the debit for gross break-even. These selected quotes are arithmetic inputs, not current Apple prices or a recommended trade.

Iron condor — another payoff structure

A short iron condor combines a put credit spread below and a call credit spread above the underlying price. With all four legs intact, its expiration payoff has a maximum gain equal to the net credit when the price lies between the short strikes. Movement beyond the range can produce a loss. Time decay and implied volatility affect its value before expiration; this structure is an example for comparison rather than a preferred trade.

A hypothetical sizing worksheet

For arithmetic practice, suppose a worksheet assigns 1-2% of a hypothetical $100,000 account to a trade's planned loss budget: that is $1,000-$2,000. These percentages are assumptions, not an institutional standard or a recommendation for a real account. Repeated losses reduce equity, and correlated positions can lose together. The percentage alone does not establish how many trades an account can withstand.

What the payoff diagram leaves out

Costs and poor fills can change realised results. American-style short options can be assigned before expiration. Exercise or assignment of only one leg can leave stock exposure, particularly near a strike at expiration. A bounded payoff diagram assumes the legs are maintained and resolved together; it is not a guarantee about every account outcome. Closing a spread can reduce remaining expiration exposure but adds execution costs and cannot undo earlier assignment.

Worksheet comparison

Calculate the bull call example at expiration prices of $175, $182 and $190. Then add an assumed $8 in total costs: the gross outcomes of -$200, $0 and +$300 become -$208, -$8 and +$292. Separately describe what could happen if the short leg were assigned and the stock position remained open. Keep that exposure separate from the intact-spread payoff.

Key takeaways

• Certain spreads have bounded theoretical expiration payoffs when their legs remain intact.
• The example's $200 debit and $300 maximum gain exclude costs and additional stock exposure.
• An iron condor's range-based payoff does not make it a preferred or safe trade.
• TradeHQ supports spot simulation; options spreads are studied in worksheets.

Check your understanding

• For the intact bull call example, maximum expiration loss before costs is: Options: Unlimited; The width of the spread; The $200 net debit; The strike price. Correct answer: The $200 net debit. Why: Both calls expire worthless below $180, leaving the $200 debit as the gross loss. Costs and separate stock exposure are excluded.
• An intact short iron condor has its maximum gross expiration gain when the underlying: Options: Rallies sharply beyond the upper wing; Crashes beyond the lower wing; Finishes between the short strikes; Goes to zero. Correct answer: Finishes between the short strikes. Why: The four options expire without intrinsic value between the short strikes, leaving the credit before costs.
• In the worksheet, 1-2% of a hypothetical $100,000 account equals: Options: $50,000; $25,000; $1,000-$2,000; $100. Correct answer: $1,000-$2,000. Why: 100,000 × 0.01 to 0.02 = $1,000-$2,000. The percentages are illustrative assumptions, not a universal standard.
• Why can an expiration payoff diagram understate account exposure? Options: It guarantees a profit; It includes all commissions; Assignment of one leg can leave a stock position; Spreads cannot lose. Correct answer: Assignment of one leg can leave a stock position. Why: The intact-spread payoff assumes both legs are resolved together. Assignment can create separate stock exposure and costs.
