What is the CAL mnemonic for Series 7 options spreads?

CAL stands for Call spreads → Add to Lower strike. To find the breakeven of any call spread (debit or credit), take the lower strike price and add the net premium (net debit or net credit). Example: Long 50 Call @ 4, Short 60 Call @ 2. Net Debit = 2. Breakeven = 50 + 2 = 52.

What is the PUSH mnemonic for Series 7 put spreads?

PUSH stands for Put spreads → Subtract from Higher strike. To find the breakeven of any put spread (debit or credit), take the higher strike price and subtract the net premium. Example: Long 60 Put @ 5, Short 50 Put @ 2. Net Debit = 3. Breakeven = 60 - 3 = 57.

What is the SILO mnemonic for straddles on the Series 7?

SILO stands for Short Inside / Long Outside. A straddle has two breakeven points: Strike + Total Premium (upper) and Strike - Total Premium (lower). For a Short Straddle, profit is between these points (inside). For a Long Straddle, profit is outside these points.

How do you calculate max gain and max loss on a debit spread for the Series 7?

For a debit spread: Max Loss = Net Debit Paid. Max Gain = Difference in Strikes minus Net Debit. The investor pays net premium upfront (debit), so the most they can lose is what they paid. The most they can gain is the spread width minus what they paid.

How do you calculate max gain and max loss on a credit spread for the Series 7?

For a credit spread: Max Gain = Net Credit Received. Max Loss = Difference in Strikes minus Net Credit. The investor receives net premium upfront (credit), so the most they can gain is what they received. The most they can lose is the spread width minus what they received.

What is the breakeven for a covered call on the Series 7?

Covered Call Breakeven = Stock Purchase Price minus Premium Received. Max Gain = Strike Price minus Stock Cost plus Premium Received. Max Loss = Stock Cost minus Premium Received (stock drops to zero). A covered call is a neutral-to-slightly-bullish strategy that generates income on a stock position.

What is the breakeven for a protective put on the Series 7?

Protective Put Breakeven = Stock Purchase Price plus Premium Paid. Max Gain = Unlimited (stock can rise indefinitely). Max Loss = Premium Paid plus (Stock Cost minus Strike Price). A protective put is insurance — it limits downside risk on a long stock position.

What is the maximum loss on a long straddle vs a short straddle?

Long Straddle max loss = Total Premiums Paid (both options expire worthless if the stock stays at the strike). Short Straddle max loss = Unlimited (you are short a naked call, so if the stock rises indefinitely, your loss is uncapped). Long straddles profit from volatility; short straddles profit from stability.

What are the breakeven points for a straddle on the Series 7?

A straddle has two breakeven points: Upper Breakeven = Strike Price + Total Premium. Lower Breakeven = Strike Price - Total Premium. Use the SILO mnemonic: Short straddle profits Inside the breakevens, Long straddle profits Outside the breakevens.

What is the maximum loss on a short (naked) call option?

The maximum loss on a short (naked/uncovered) call is unlimited. The writer must buy shares at the market price to deliver, and the stock can theoretically rise without limit. This is the riskiest single options position. Max gain is limited to the premium received.

How do you know if a spread is a debit or credit spread?

Compare the premiums: if you pay more than you receive, it's a debit spread (you paid net). If you receive more than you pay, it's a credit spread (you received net). Debit spreads have limited risk equal to the debit paid. Credit spreads have limited risk equal to the spread width minus the credit received.

Math Check: The CAL Rule

Buy 1 XYZ 50 Call @ 4. Sell 1 XYZ 60 Call @ 2. What is your Breakeven?

Breakeven is 52.
1. Net Debit = 4 (paid) − 2 (received) = $2.
2. Use CAL (Call Spread → Add to Lower).
3. Lower Strike (50) + Net Debit (2) = 52.

💡 For spreads: Debit = you pay = max loss is the debit. Credit = you receive = max gain is the credit. The "other" number is always Diff. in Strikes minus the net premium.

⚠️

Common Exam Trap

Both straddles have the same breakeven formulas. The difference is where the profit zone falls: Short = inside (narrow, stable), Long = outside (wide, volatile). Short straddle max loss is unlimited because it includes a naked short call.

Series 7 Scenario

Max Gain Calculation: Debit Call Spread

You enter a Debit Call Spread.
Long 1 ABC 50 Call @ 6. Short 1 ABC 60 Call @ 2.
What is your Maximum Gain?

Correct!

1. Net Debit: 6 − 2 = 4.
2. Difference in Strikes: 60 − 50 = 10.
3. Max Gain (Debit Spread) = Diff. − Net Debit = 10 − 4 = 6 ($600).

We have 5,000+ options questions in our Series 7 bank.

Not quite

$400 is your Max Loss (the debit paid). $1,000 is the difference in strikes (not adjusted for cost). Max Gain = Diff. in Strikes − Net Debit = 10 − 4 = $600.
