neutral

Buy a call and a put at the same at-the-money strike. Profits if the stock moves far enough in either direction to cover both premiums; loses fastest when the stock goes nowhere.

Underlying (optional)
Market inputs

Common questions

What are the breakevens on a straddle?
Strike ± total premium paid. The stock must move beyond either bound by expiry for the position to profit.
What is the max loss?
The combined premium of the call and put, if the stock pins the strike at expiry.
When do traders use straddles?
Around binary events (earnings, rulings) where a large move is expected but the direction isn't. High implied volatility makes them expensive — the move must beat what's already priced in.

Educational model, not trade advice. Options involve substantial risk and are not suitable for every investor — read the OCC’s Characteristics and Risks of Standardized Options. Model values use Black-Scholes with your inputs (constant volatility, European exercise, no dividends) and will differ from live market prices.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
