What Is an Options Straddle?
A straddle is a two-leg options strategy that involves buying (or selling) both a call and a put on the same stock at the same strike price and the same expiration date. Because it holds both a call and a put at the identical strike, a straddle profits from large price movement in either direction — up or down — without requiring a directional bet.
The straddle comes in two forms with opposite risk profiles: the long straddle (buy both legs) and the short straddle (sell both legs).
Long Straddle vs. Short Straddle
Long Straddle
Buy an ATM call + Buy an ATM put at the same strike and expiration.
- Profits from a large move in either direction
- Maximum loss: total premium paid
- Maximum gain: unlimited (call side) or strike price (put side)
- Best used before high-volatility events
Short Straddle
Sell an ATM call + Sell an ATM put at the same strike and expiration.
- Profits from the stock staying near the strike (little movement)
- Maximum gain: total premium collected
- Maximum loss: unlimited (call side) — high risk without hedges
- Best used in low-volatility, range-bound conditions
Straddle Formulas — Breakeven, Profit, and Loss
Long Straddle
- Buy $100 call for $4.00
- Buy $100 put for $3.50
- Total premium paid: $7.50
- Maximum loss: $7.50 (if stock closes exactly at $100 at expiration)
- Upper breakeven: $107.50 — stock must rise above this to profit
- Lower breakeven: $92.50 — stock must fall below this to profit
- Maximum gain: unlimited to the upside; $92.50 to the downside (stock to zero)
Straddles and Earnings — The Most Common Use Case
The single most common reason retail traders buy straddles is to position ahead of an earnings announcement. The thesis is straightforward: earnings can cause large moves in either direction, and a straddle profits from a large move regardless of direction. You do not need to know whether the company will beat or miss — only that the move will be large enough to cover the premium paid.
The volatility crush risk: Implied volatility inflates significantly heading into earnings, making straddle premiums expensive. Immediately after the announcement, IV collapses — sometimes by 40–60%. Even if the stock moves significantly, the IV crush can erode enough option value that the straddle loses money. This is why many experienced traders avoid buying straddles unless the expected move is substantially larger than the premium paid. OptionsVault's earnings calendar and IV explainer help you assess this risk before entering.
How to evaluate a straddle before earnings
- Calculate the implied move: Add the call and put premiums at the ATM strike. This sum approximates what the options market is pricing in as the expected move. If the straddle costs $7.50 on a $100 stock, the market implies a ±7.5% move.
- Compare to historical earnings moves: If this stock has historically moved ±10% on earnings and the straddle costs 7.5%, the trade looks attractive. If it historically moves ±5%, you need a larger-than-average move just to break even.
- Check current IV vs. historical IV: If IV is at a multi-year high heading into earnings, the straddle is expensive. High IV already prices in a large move — you may be paying a premium the stock cannot realistically deliver.
Straddle vs. Strangle
A strangle is similar to a straddle but uses different strike prices for the call and put — typically both out of the money. This makes the strangle cheaper to enter than a straddle (you pay less premium) but requires a larger move to reach breakeven. Straddles use ATM strikes for both legs; strangles use OTM strikes. The straddle starts losing immediately if the stock stays flat; the strangle has more cushion before decay hurts, but needs a bigger move to profit.
Pricing a Straddle with the OptionsVault Calculator
To price a straddle, open OptionsVault and price both legs separately — the ATM call and the ATM put at your chosen strike and expiration. Add the two premiums together to get your total cost and calculate your breakeven levels using the formulas above. You can also use the live Greeks on each leg to understand your net position: the call's Delta and the put's Delta will be roughly equal and opposite near ATM, giving you a near-zero net Delta — meaning the position is not directional, just a volatility bet.
