Short Straddle Payoff & Breakeven

🔑 Position summary — Short straddle

⚠️ Straddles have TWO breakevens — they are one of the only options strategies with multiple breakevens. To find both quickly:

1. Add up the combined premiums.
2. Add the combined premiums to the strike price (upside breakeven).
3. Subtract the combined premiums from the strike price (downside breakeven).

⚠️ Max-loss asymmetry: long vs. short straddle

Concept

• Short straddles are essentially the opposite of long straddles. Long straddles can profit when the market is volatile; conversely, short straddles can profit when the market is flat (neutral).

Definitions

Example position:

Short 1 ABC Jan 60 call Short 1 ABC Jan 60 put

• By selling both options, the investor is betting on market neutrality (little to no price movement).
• If the market price stays flat, both options may expire worthless. That happens when ABC’s market price is exactly the shared strike price at expiration, which is the best-case scenario for a short straddle.
• ⚠️ If the market price rises, the call will be assigned (exercised). This is the most dangerous direction — the short call obligates the investor to sell shares at the strike price. If the investor doesn’t already own the shares, they must buy them at the higher market price and then sell at the lower strike price. The higher the market price rises, the larger the loss.
• ⚠️ If the market price falls, the put will be assigned (exercised). This also creates significant risk — the short put obligates the investor to buy shares at the strike price even though the market price is lower. The further the market price falls, the more the investor overpays, and the larger the loss.
• A short straddle is risky because it involves two naked (uncovered) options. However, the investor receives two premiums up front. Losses must exceed the combined premiums before the investor has an overall loss. The investor is most likely to profit when the stock’s market price doesn’t move dramatically.

Worked examples — Short 1 ABC Jan 60 call at $4 + Short 1 ABC Jan 60 put at $5 (ABC at $60)

Market rises to $120

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market rises to $120?

Answer = $5,100 loss

Action	Result
Sell call	+$400
Sell put	+$500
Buy shares	-$12,000
Call assigned - sell shares	+$6,000
Total	-$5,100

At $120, the call is “in the money” (has intrinsic value) and the put is “out of the money” (no intrinsic value). The put expires worthless, but the call is assigned (exercised), requiring the investor to fulfill the obligation to sell.

The investor buys the stock in the market at $120 and then sells at $60, creating a $60 loss per share, or $6,000 total ($60 x 100 shares). The $900 combined premium received up front reduces the loss to $5,100.

• The investor wanted a flat market and got the opposite. Even though only one option went in the money, the short call produced a large loss. The premiums offset the loss slightly, but the overall result is still substantial.
• 🔑 ⚠️ Short straddle maximum loss = unlimited. The further the market rises, the larger the loss because of the short naked call.

Market rises to $69 (upside breakeven)

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price rises to $69?

Answer = $0 (breakeven)

Action	Result
Sell call	+$400
Sell put	+$500
Buy shares	-$6,900
Call assigned - sell shares	+$6,000
Total	$0

At $69, the call is “in the money” (has intrinsic value) and the put is “out of the money” (no intrinsic value). The put expires worthless, but the call is assigned (exercised).

The investor buys the stock at $69 and sells at $60, creating a $9 loss per share, or $900 total ($9 x 100 shares). The $900 combined premium received up front offsets the loss, resulting in breakeven.

• 🔑 On the upside, the straddle breaks even when the loss on the short call equals the combined premiums. Upside breakeven = Strike price ($60) + combined premium ($9) = $69.

Market rises to $64

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price rises to $64?

Answer = $500 gain

Action	Result
Sell call	+$400
Sell put	+$500
Buy shares	-$6,400
Call assigned - sell shares	+$6,000
Total	+$500

At $64, the call is “in the money” (has intrinsic value) and the put is “out of the money” (no intrinsic value). The put expires worthless, but the call is assigned (exercised).

The investor buys the stock at $64 and sells at $60, creating a $4 loss per share, or $400 total ($4 x 100 shares). The $900 combined premium received up front more than offsets that loss, leaving a $500 gain.

• 📌 A short straddle works best when the stock stays close to the shared strike price. Small moves can still be profitable because the premiums provide a cushion.

Market stays flat at $60 (maximum gain)

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price stays at $60?

Answer = $900 gain

Action	Result
Sell call	+$400
Sell put	+$500
Total	+$900

At $60, both options are “at the money” and expire worthless (contracts must have intrinsic value to be exercised). The investor keeps the entire $900 in combined premiums.

• This is the best-case scenario and produces the maximum gain.
• 🔑 Short straddle maximum gain = combined premiums. (Page wording: “The maximum gain for a short put can be found by using this formula: Short straddle maximum gain = combined premiums.”)

Market falls to $59

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price falls to $59?

Answer = $800 gain

Action	Result
Sell call	+$400
Sell put	+$500
Put assigned - buy shares	-$6,000
Share value	+$5,900
Total	+$800

At $59, the put is “in the money” (has intrinsic value) and the call is “out of the money” (no intrinsic value). The call expires worthless, but the put is assigned (exercised).

The investor buys shares for $60 that are worth $59, creating a $1 loss per share, or $100 total ($1 x 100 shares). The $900 combined premium received up front offsets the loss, resulting in an $800 gain.

• Again, the closer the stock stays to the shared strike price, the more likely the investor profits.

Market falls to $51 (downside breakeven)

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price falls to $51?

Answer = $0 (breakeven)

Action	Result
Sell call	+$400
Sell put	+$500
Put assigned - buy shares	-$6,000
Share value	+$5,100
Total	$0

At $51, the put is “in the money” (has intrinsic value) and the call is “out of the money” (no intrinsic value). The call expires worthless, but the put is assigned (exercised).

The investor buys shares for $60 that are worth $51, creating a $9 loss per share, or $900 total ($9 x 100 shares). The $900 combined premium received up front offsets the loss, resulting in breakeven.

• 🔑 On the downside, the straddle breaks even when the loss on the short put equals the combined premiums. Downside breakeven = Strike price ($60) − combined premium ($9) = $51.
• In summary, the two breakevens for this example are $51 and $69.

Market falls to $25

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. What is the gain or loss if ABC’s market price falls to $25?

Answer = $2,600 loss

Action	Result
Sell call	+$400
Sell put	+$500
Put assigned - buy shares	-$6,000
Share value	+$2,500
Total	-$2,600

At $25, the put is “in the money” (has intrinsic value) and the call is “out of the money” (no intrinsic value). The call expires worthless, but the put is assigned (exercised).

The investor buys shares for $60 that are worth $25, creating a $35 loss per share, or $3,500 total ($35 x 100 shares). The $900 combined premium received up front reduces the loss to $2,600.

• The investor wanted a flat market and got a large downward move. Even though only one option went in the money, the short put produced a large loss. The premiums offset the loss slightly, but the overall result is still substantial.

Payoff chart summary

Position again:

Short 1 ABC Jan 60 call @ $4 Short 1 ABC Jan 60 put @ $5

What the page says the chart shows:

• The horizontal axis represents the market price of ABC stock; the vertical axis represents overall gain or loss.
• The investor reaches the maximum gain of $900 when the market price is $60. At that point, both options expire worthless, and the combined premiums are the profit.
• If the market price rises above or falls below $60, the call or the put goes “in the money” and gains intrinsic value.
• 🔑 Remember: option writers (sellers) lose when their contracts gain intrinsic value. Intrinsic value benefits the holder (buyer, long side) and hurts the writer (seller, short side).
• If the market price rises to $69, the short call gains $9 of intrinsic value, which offsets both premiums. Any price above $69 produces a loss, and the upside loss potential is unlimited.
• If the market price falls to $51, the short put gains $9 of intrinsic value, which offsets both premiums. Any price below $51 produces a loss, and the downside loss continues until the stock reaches $0.
• Any market price below $51 results in a loss as the investor is eligible for up to $5,100 of liability (a $5,100 loss would occur if the market price falls to $0).

Closing out at intrinsic value

• Closing out contracts means trading the contracts instead of waiting for assignment or expiration.
• 🔑 Both options were sold to open (opening sales), so both must be bought to close (closing purchases).

Market falls to $40, contracts closed at intrinsic value

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. ABC’s market price falls to $40 and the investor closes the contracts at intrinsic value. What is the gain or loss?

Answer = $1,100 loss

Action	Result
Sell call	+$400
Sell put	+$500
Close call	$0
Close put	-$2,000
Total	-$1,100

At $40, the put is “in the money” (has intrinsic value) and the call is “out of the money” (no intrinsic value).

• The call has $0 of intrinsic value, so the investor closes the call by buying it for $0 (closing purchase).
• The put has $20 of intrinsic value, so the investor closes the put by buying it for $20 (closing purchase).

The investor received $9 in total premium up front but pays $20 to close the put. That difference is an $11 loss per share, or $1,100 total ($11 x 100 shares).

After selling $900 of options and buying to close for $2,000, the investor has a $1,100 loss.

Market rises to $67, contracts closed at intrinsic value

An investor goes short 1 ABC Jan 60 call at $4 and short 1 ABC Jan 60 put at $5 when ABC’s market price is $60. ABC’s market price rises to $67 and the investor closes the contracts at intrinsic value. What is the gain or loss?

Answer = $200 gain

Action	Result
Sell call	+$400
Sell put	+$500
Close call	-$700
Close put	$0
Total	+$200

At $67, the call is “in the money” (has intrinsic value) and the put is “out of the money” (no intrinsic value).

• The put has $0 of intrinsic value, so the investor closes the put by buying it for $0 (closing purchase).
• The call has $7 of intrinsic value, so the investor closes the call by buying it for $7 (closing purchase).

The investor received $9 in total premium up front and pays $7 to close the call. That difference is a $2 gain per share, or $200 total ($2 x 100 shares).

After selling $900 of options and buying to close for $700, the investor has a $200 gain.

Suitability

• 📌 For suitability, short straddles should only be recommended to aggressive options traders with a substantial net worth when a flat market is expected.
• ⚠️ If there is unexpected volatility, the investor is subject to unlimited risk. The fewer assets or money an investor has, the less likely they should be selling straddles.

Key points

Short straddles

• Short call & short put
  • Must be the same strike & expiration
• Market sentiment: flat/neutral

Short straddle formulas

• Maximum gain = combined premiums
• Maximum loss = unlimited
• Breakevens = strike +/- combined premiums
