Spreads and Combinations

Spreads involve simultaneously buying and selling options of the same type (both calls or both puts) on the same underlying security. These strategies limit both risk and reward.

Spread Basics

Debit Spread vs. Credit Spread

TypeNet PremiumMarket ExpectationMax Gain
Debit SpreadPay premiumExpect significant moveDifference in strikes minus net premium
Credit SpreadReceive premiumExpect limited moveNet premium received

Memory Tip: "Buy low, sell high" applies to strikes too. In a debit spread, you're buying the more expensive option.

Bull Call Spread (Debit Spread)

Buy a call at a lower strike, sell a call at a higher strike. Used when moderately bullish.

Example

  • Buy 1 XYZ 50 Call @ $5
  • Sell 1 XYZ 55 Call @ $2
  • Net Debit = $3
CalculationFormulaResult
Maximum Gain(Higher Strike - Lower Strike) - Net Premium($55 - $50) - $3 = $200
Maximum LossNet Premium Paid$3 × 100 = $300
BreakevenLower Strike + Net Premium$50 + $3 = $53

Bear Put Spread (Debit Spread)

Buy a put at a higher strike, sell a put at a lower strike. Used when moderately bearish.

Example

  • Buy 1 XYZ 55 Put @ $5
  • Sell 1 XYZ 50 Put @ $2
  • Net Debit = $3
CalculationFormulaResult
Maximum Gain(Higher Strike - Lower Strike) - Net Premium($55 - $50) - $3 = $200
Maximum LossNet Premium Paid$3 × 100 = $300
BreakevenHigher Strike - Net Premium$55 - $3 = $52

Credit Spreads

Bull Put Spread (Credit Spread)

Sell a put at a higher strike, buy a put at a lower strike. Used when moderately bullish.

  • Receive net premium
  • Maximum gain = Premium received
  • Maximum loss = Difference in strikes - Premium received

Bear Call Spread (Credit Spread)

Sell a call at a lower strike, buy a call at a higher strike. Used when moderately bearish.

  • Receive net premium
  • Maximum gain = Premium received
  • Maximum loss = Difference in strikes - Premium received

Straddles

A straddle involves buying or selling both a call and a put with the same strike price and expiration.

Long Straddle

  • Buy 1 XYZ 50 Call @ $3
  • Buy 1 XYZ 50 Put @ $2
  • Total Premium = $5
AspectDetails
Market ViewExpect HIGH volatility (big move either direction)
Maximum GainUnlimited (if stock rises) or Strike - Premium (if stock falls)
Maximum LossTotal premium paid ($500)
Breakeven Points$50 + $5 = $55 (upside) and $50 - $5 = $45 (downside)

Short Straddle

  • Sell 1 XYZ 50 Call @ $3
  • Sell 1 XYZ 50 Put @ $2
  • Total Premium = $5
AspectDetails
Market ViewExpect LOW volatility (stock stays near strike)
Maximum GainTotal premium received ($500)
Maximum LossUnlimited
Breakeven Points$50 + $5 = $55 and $50 - $5 = $45

Exam Alert: Long straddles profit from volatility. Short straddles profit from stability. The exam often tests which strategy fits which market outlook.

Strangles

A strangle is similar to a straddle but uses different strike prices (usually both out-of-the-money).

Long Strangle

  • Buy 1 XYZ 55 Call @ $2
  • Buy 1 XYZ 45 Put @ $1
  • Total Premium = $3
AspectDetails
Market ViewExpect HIGH volatility
Maximum LossTotal premium paid ($300)
Lower CostCheaper than straddle because both options are OTM
Breakeven Points$55 + $3 = $58 and $45 - $3 = $42
