Short Put Butterfly (Buy 2 ATM Put, Sell 1 ITM Put, Sell 1 OTM Put)



Short Put Butterfly (Buy 2 ATM Put, Sell 1 ITM Put, Sell 1 OTM Put)

A Short Put Butterfly is a strategy for volatile markets. It is the opposite of Long Put Butterfly, which is a range bound strategy. The Short Put Butterfly can be constructed by Selling one lower striking in-the-money Put, buying two at-the-money Put and selling another higher strike out-of-the-money Put, giving the investor a net credit (therefore it is an income strategy). There should be equal distance between each strike. The resulting position will be profitable in case there is a big move in the stock / index.

Market Scenario: neutral on market direction and bullish on volatility.

Risk: Limited (net difference between the adjacent strikes (Rs. 100 in this example) - premium

Reward: Limited to the net premium received

BEP:   Upper BEP = Strike Price of Highest Strike Short Put - Net Premium Received
            Lower BEP = Strike Price of Lowest Strike Long Put + Net Premium Received
