| Short Call Butterfly Profile Chart | ||
|
Short Call Butterfly is a combination of Bear Call Spread and Bull Call Spread. Its risk profile is the exact opposite of Long Call Butterfly and least popular. Also, the risk reward ratio is not attractive even though it’s a low cost strategy.
Traders are more inclined to use Straddle or Strangle because even though those strategies are slightly more expensive, the rewards are not seriously capped like in Short Call Butterfly.
