What Is a Ratio Spread?
A ratio spread is an options strategy that involves buying and selling options of the same type (calls or puts) with the same expiration date but at different strike prices, where the number of contracts sold differs from the number bought. The most common configuration is a 1:2 ratio — buying one option at one strike and selling two options at a different strike — but traders can use any ratio such as 1:3, 2:3, or 2:5 depending on their market outlook and risk tolerance.
Ratio spreads are popular among experienced options traders because they can be established for a net credit (or very small debit), provide limited risk in one direction, and offer substantial profit potential if the underlying asset moves to the short strike at expiration. However, they carry unlimited risk on the side with excess short contracts, making proper risk analysis essential before entering the trade.

Common Ratio Spread Strategies
- Call Ratio Spread (1:2): Buy 1 ITM or ATM call, sell 2 OTM calls. Profits if the stock rises moderately to the short strike. Risk is unlimited above the upper breakeven.
- Put Ratio Spread (1:2): Buy 1 ITM or ATM put, sell 2 OTM puts. Profits if the stock falls moderately to the short strike. Risk increases if the stock drops significantly below the lower breakeven.
- Call Ratio Backspread (2:1): Buy 2 OTM calls, sell 1 ITM call. Profits from a large upward move. Limited risk if the stock stays flat or declines moderately.
- Put Ratio Backspread (2:1): Buy 2 OTM puts, sell 1 ITM put. Profits from a large downward move. Limited risk if the stock stays flat or rises moderately.
