Quick Answer
Spreads pair two options of the same class and cap both gain and loss; straddles pair a call and a put to bet on movement; and uncovered writing collects premium at open-ended risk. Debit spreads want movement, credit spreads want stillness, and a naked call carries unlimited loss. Nail max gain, max loss, and breakeven for each.
The whole unit on one sheet: how to classify a multi-leg position, and how to nail its max gain, max loss, and breakeven.
Spreads: Classify First
- A spread is the simultaneous purchase and sale of two options of the same class (both calls or both puts), same underlying. Both max gain and max loss are capped.
- Vertical (price) spread: same expiration, different strikes (the exam's focus). Time (horizontal/calendar) spread = same strike, different months. Diagonal = both differ.
- Debit = you NET paid (cash out); credit = you NET received (cash in). The higher-premium option sets the direction.
- Bullish spreads profit when the stock rises; bearish spreads profit when it falls. To tell which, look at the option that was BOUGHT.
The One-Liners That Win Points
- Debit spreads want movement; credit spreads want stillness. A debit holder wants both options exercised; a credit writer wants both to expire worthless.
- For every vertical spread: Max gain + Max loss = spread width (difference in strikes). If they do not sum to the strike difference, recheck.
- Bull call and bear call with the same strikes share one breakeven (lower strike + net premium). Bear put and bull put share one too (higher strike minus net premium).
- A straddle is NOT a spread. Spreads use one class; a straddle pairs a call AND a put, same strike and expiration.
- "Wants volatility" = long straddle; "wants stability" = short straddle. Long profits outside the breakevens; short profits between them.
- Uncovered (naked) call writing is the single highest-risk strategy: loss is unlimited. An uncovered put has LIMITED risk (stock can only fall to zero).
- Cash-flow tracking (T-chart) works for any position: total cash in minus total cash out. Buying stock (exercise or assignment) is cash out; selling stock is cash in.
- Index options settle in cash, European-style (OEX is the American-style exception). Multiplier is $100.
Numbers to Lock In
| Item | Value |
|---|---|
| Debit spread max loss | Net premium paid |
| Debit spread max gain | Spread width minus net debit |
| Credit spread max gain | Net premium received |
| Credit spread max loss | Spread width minus net credit |
| Call spread breakeven | Lower strike + net premium |
| Put spread breakeven | Higher strike minus net premium |
| Long straddle max loss | Total premiums paid (at exactly the strike) |
| Straddle breakevens | Strike + total premiums / Strike minus total premiums |
| Uncovered call breakeven and risk | Strike + premium; loss unlimited |
| Uncovered put max loss and breakeven | Strike minus premium |

Spreads and Straddles at a Glance
| Strategy | Type | Outlook | Max Gain | Max Loss | Breakeven |
|---|---|---|---|---|---|
| Bull call spread | Debit | Bullish | (High - Low) - debit | Net debit | Low strike + debit |
| Bear call spread | Credit | Bearish | Net credit | (High - Low) - credit | Low strike + credit |
| Bear put spread | Debit | Bearish | (High - Low) - debit | Net debit | High strike - debit |
| Bull put spread | Credit | Bullish | Net credit | (High - Low) - credit | High strike - credit |
| Long straddle | Debit | Big move | Unlimited (upside) | Total premiums | Strike +/- total premiums |
| Short straddle | Credit | Flat | Total premiums | Unlimited (upside) | Strike +/- total premiums |
Memory Aid: CAL/PUSH for Spread Breakevens
- CAL = Call Add Lower: for any call spread, add the net premium to the lower strike.
- PUSH = Put sUbtract Higher: for any put spread, subtract the net premium from the higher strike.
- Works for debit or credit; just plug in the absolute value of the net premium.
Top Gotchas
- A bear put spread is still a debit even though "sell" appears in its structure: the bought higher-strike put costs more than the sold lower-strike put.
- Max loss on a long straddle occurs at exactly the strike (both options at the money); any move away from the strike reduces the loss.
- Short straddles and short combinations have unlimited upside risk from the naked call; a combination (strangle) just widens the profit zone, it does not reduce risk.
- A ratio call write has unlimited upside risk like an uncovered call: only the first call is covered, every extra call written is naked. Two breakeven points, like a straddle.
- A yield-based call is NOT a bond call: it profits when rates RISE (bond prices fall). To hedge a bond portfolio against rising rates, buy yield-based calls, not puts. A TYX 35 call references a 3.5% yield (decimal after the first digit).
- A spread's max value at expiration equals the spread width, not an unlimited amount; that is what makes it defined-risk.
One-Breath Recap
Spreads pair two same-class options and cap both ends, so debit spreads chase movement while credit spreads collect premium and want stillness, and every vertical's max gain plus max loss equals the spread width. Straddles pair a call and a put to bet on volatility, long profiting outside the breakevens and short between them, while naked call writing runs unlimited risk. Lock in max gain, max loss, and breakeven and the T-chart handles anything the exam throws at you.
