Short
Call Butterfly
Description
The
Short Call Butterfly is another volatility strategy and is the opposite of a
Long Call Butterfly, which is a rangebound strategy. The reason that short butterflies
are not particularly popular is because even though they produce a net credit,
they offer very small returns compared to straddles and strangles with only
slightly less
risk.
The
Short Call Butterfly involves a low strike short call, two ATM long calls, and
an out-of-the-money short call. The resulting position is profitable in the
event of a big move by the stock. The problem is that the reward is seriously
capped and is typically dwarfed by the potential risk if the stock fails to
move.
