- A purchased call option with a strike price right at the underlying stock's price.
- A purchased put option with the same strike price and expiration date as the long call option.
The options trade straddles the current stock price, hence the strategy's name. For example, if a stock trades at $100 a share, an investor would buy a $100 call and purchase a $100 put to set up a long straddle. They would pay a net debit (the cost of buying the call and put option) to set up this trade. That debit represents their maximum risk.
The trade would make money as long as the underlying stock or market index finishes above or below the strike price plus the net debit they incurred to set up the trade. For example, if they paid $2 per share for the call (or $200 per contract since each options contract is typically 100 shares) and $2 per share for the put, their combined net debit would be $4 per share ($400 total). Thus, their breakeven on this trade would be $104 on the upside and $96 on the downside. The trade would make money as long as the underlying price closes above or below those breakeven levels. Meanwhile, the options trader would lose money on the trade if it closed anywhere between their breakeven levels, with a maximum loss occurring if the stock closed precisely at the $100 strike price.
