Straddles
Spreads involve two options of the same class (both calls or both puts). Now we shift to strategies that combine different classes: a call AND a put on the same stock. When the call and put share the same strike price and expiration, that combination is called a straddle.
What Is a Straddle?
- A straddle is the simultaneous purchase (or sale) of a call and a put on the same underlying security with the same strike price and the same expiration month
- Unlike a spread, a straddle uses options of different classes (one call + one put)
- Straddles are volatility plays. The investor is betting on how much the stock will move, not which direction
Exam Tip: Gotchas
- A straddle is NOT a spread. Spreads use the same class (both calls or both puts). Straddles combine different classes (one call + one put). If the exam describes buying a call and a put with the same strike and expiration, that is a straddle, not a spread.
Long Straddle (Buying a Straddle)
- Structure: Buy a call + buy a put on the same stock, same strike, same expiration
- Market outlook: Expects high volatility; anticipates a large price move in either direction but is uncertain which way
- Cost: The investor pays two premiums (call + put), making this an expensive strategy
| Component | Formula |
|---|---|
| Max gain (upside) | Unlimited (stock can rise without limit) |
| Max gain (downside) | Strike price minus total premiums paid |
| Max loss | Total premiums paid (call + put) |
| Upside breakeven | Strike + total premiums |
| Downside breakeven | Strike minus total premiums |
Think of it this way: You are paying for two lottery tickets on the same stock. One pays off if the stock soars, the other pays off if it tanks. You lose only if the stock sits still, because both tickets expire worthless.
Example: Buy 1 XYZ Oct 50 call at 4 / Buy 1 XYZ Oct 50 put at 3
- Total premiums = $4 + $3 = $7
- Max loss = $7 (occurs when the stock is at exactly $50 at expiration, so both options are at the money)
- Upside breakeven = $50 + $7 = $57
- Downside breakeven = $50 - $7 = $43
- The stock must move more than $7 in either direction to profit
When to use: Before an earnings announcement, FDA ruling, court decision, or any event expected to cause a big move when you are not sure which direction
Exam Tip: Gotchas
- Max loss on a long straddle occurs when the stock closes at exactly the strike price. Both options expire at the money and the investor loses both premiums. Any movement away from the strike reduces the loss.
- Time decay works against the long straddle buyer. Every day that passes without a big move erodes the value of both options.
Short Straddle (Selling/Writing a Straddle)
- Structure: Sell a call + sell a put on the same stock, same strike, same expiration
- Market outlook: Expects low volatility; anticipates the stock price will remain near the strike price (stable market)
- Income: The investor collects two premiums upfront
| Component | Formula |
|---|---|
| Max gain | Total premiums received |
| Max loss (upside) | Unlimited (stock can rise without limit) |
| Max loss (downside) | Strike price minus total premiums received |
| Upside breakeven | Strike + total premiums |
| Downside breakeven | Strike minus total premiums |
When max gain occurs: The stock is at exactly the strike price at expiration. Both options expire worthless and the writer keeps both premiums.
When max loss occurs: The stock makes a large move in either direction, and the loss on the in-the-money option exceeds the total premiums collected.

- Short straddles have unlimited risk on the upside. The short call has no ceiling on losses if the stock keeps rising. This makes the short straddle one of the riskiest options strategies.
- The ideal outcome for the short straddle writer is zero movement. The best-case scenario is the stock closing at exactly the strike price, not just "near" it.
Long vs. Short Straddle Comparison
| Feature | Long Straddle | Short Straddle |
|---|---|---|
| Market view | High volatility expected | Low volatility expected |
| Cash flow at opening | Pay premiums (debit) | Collect premiums (credit) |
| Max gain | Unlimited (upside) | Total premiums received |
| Max loss | Total premiums paid | Unlimited (upside) |
| Breakeven points | Two (same for both) | Two (same for both) |
| Time decay | Works against | Works in favor |
| Risk level | Limited (premium paid) | Unlimited |
Exam Tip: Gotchas
- The breakeven points are identical for the long and short straddle with the same terms. The difference is which side profits above or below those points. The long straddle profits outside the breakevens; the short straddle profits between them.
- "Wants volatility" = long straddle. "Wants stability" = short straddle. If the exam says an investor expects a big move but is unsure of direction, the answer is a long straddle. If the investor expects the stock to stay flat, the answer is a short straddle.
