A Short Call Butterfly is a strategy for volatile markets. It is the opposite of Long Call Butterfly, which is a range bound strategy. The Short Call Butterfly can be constructed by Selling one lower striking in-the-money Call, buying two at-the-money Calls and selling another higher strike out-of-the-money Call, 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. The maximum risk occurs if the stock/index is at the middle strike at expiration. However, this strategy offers very small returns when compared to straddles, strangles with only slightly less risk.
When to use: You are neutral on market direction and bullish on volatility. Neutral means that you expect the market to move in either direction—i.e. bullish and bearish.
Risk: Limited to the net difference between the adjacent strikes (Rs. 100 in this example) less the premium received for the position.
Reward: Limited to the net premium received for the option spread.
