What is a long straddle?
A long straddle involves buying an at-the-money call and an at-the-money put at the same strike and expiry. You pay a debit upfront. The trade profits if the underlying makes a large move in either direction — you don't need to predict which way.
If the stock surges, the call gains value. If it crashes, the put gains value. The only way to lose the full premium is if the stock closes exactly at the strike at expiry.
When to use it
Straddles are popular ahead of binary events where a large move is expected but direction is uncertain — earnings announcements, FDA decisions, legal rulings, or central bank decisions.
Crucially, implied volatility should be relatively low when you buy the straddle. If IV is already elevated (the market has already 'priced in' a big move), you'll pay up for the options and need an even larger move to profit. The classic mistake is buying a straddle into high IV.
Construction
1. Buy 1 ATM call at your chosen strike and expiry
2. Buy 1 ATM put at the same strike and expiry
The strike is typically the at-the-money strike (closest to the current price). The total debit paid is your maximum loss.
Profit, loss, and breakevens
Max profit: unlimited to the upside (the call has unlimited upside). To the downside, max profit is strike price minus zero (stock goes to zero) minus debit paid.
Max loss: total premium paid. This occurs if the stock closes exactly at the strike at expiry — both options expire worthless.
Upper breakeven: strike price + total premium paid
Lower breakeven: strike price − total premium paid
Key risks
IV crush: after a binary event (e.g. earnings), implied volatility typically collapses sharply. Even if the stock moves, the drop in IV can erode the value of both options, leading to a loss. This is the most common straddle pitfall.
Time decay (theta) constantly works against you as a buyer of options. The position loses value every day the underlying stays near the strike.
The required move to break even is often larger than it appears — the stock must move enough to overcome the total premium paid on both legs.
